Forum Rules *ALL NEW MEMBERS, PLEASE READ!! UPDATED!!*

First and foremost, Welcome to the Badcaps Capacitor Search Engine & Forums!

New members that have activated their accounts have limited access to certain features of the site until established. Members with zero posts have no access to the private messaging system. Also, members with zero posts may not edit certain profile attributes, such as signatures. New members also may not create new threads. However, new members with zero posts have full access to all technical information contained on this forum, and that also includes attachments (images and files that other members have uploaded), and new members that have activated their accounts are free to post replies to existing threads. If you wish to create a new thread, the fix is simple! All you need is ONE post to be able to have full unrestricted access, and that can be simply posting an introduction of yourself or say hello in THIS THREAD. This may seem a little strange, but it helps keep spam and abuse curved. Please note, that it may take up to one hour from your first post for the limits to be removed. If you make a post and don't immediately see the restrictions gone, be patient. The promotion system updates every hour.

Please complete your profile after making your first post, with your name, locale, and other info. It's nice to know members on a first name basis, and know where they're from. Makes for a much friendlier environment!

Posting rules for this forum will be STRICTLY enforced by myself as the owner/administrator, and my moderator crew.

Badcaps.net IS A BUSINESS!!! If you are a servicer, service center, or vendor of any kind in the computer/capacitor industry, you are NOT permitted to advertise, link, promote, or plug your business on this forum in ANY way! NO EXCEPTIONS!! This includes asking for "donations" in exchange for BIOS passwords or tech advice for anything! If I see you doing that, your post will be edited or deleted, and you warned. If it happens again, you will be banned. The only exceptions are the references to the companies quoted in the FAQ which the administration have added for the convenience of those around the world who have difficulty to source caps for their repair.

This also includes using this forum's private message system to solicit business. Members, if you receive a PM from anyone offering repair services or components, please alert me immediately! Myself or any of my moderators, will never private message a user soliciting business, for Badcaps.net, or any other servicer/vendor. If you PM me about repairing your device, I will reply and take care of you, however, I will not message you first.

Posting rules:

This forum was created to be a technical support forum primarily for the do-it-yourselfers who choose to repair their own boards. Any and all technical questions are welcome!

1) Please use the SEARCH feature!! Your question may have been answered in another thread! Please search first and see if it has!

2) When posting a technical question, be as detailed as possible in your thread. The more information we have about your specific problem, the better we can answer your question.

3) Please use COMPLETE sentences, punctuation, and grammar! Nobody is perfect, hence, a spelling error on occasion is no biggie. However, posts/threads that are unreadable will be deleted. This includes any and all forms of 'ebonics', leet, chatroom jargon, and 'text message' shorthand and slang. This forum is not a chatroom/text message, please use full words and complete sentences.

4) Keep discussion on topic!! DO NOT HIJACK THREADS! It's easy to do (I've done it myself a few times...) Lets try to keep it down to a minimal!! If you have something really off topic, that's what the lounge is for!

5) Keep things civil! There will be no tolerance for flaming, bashing, hateful remarks, racial remarks, adult material of ANY kind, and so on.

6) THE LOUNGE RULES! The lounge is a place for off topic chit-chat! If you post something that might be considered questionable or something you don't want kids to see, or something you can't view at work/school, etc, please label that thread *NWS* or NOT WORK SAFE in the thread title as a warning. The Lounge is NOT moderated, anything is welcome... Feel free to post rants, jokes, cars, hot women (remember the NWS warning in the title), or just about anything within reason. It's an open forum! Please refrain from participating in political topics if you have thin skin, they can get heated sometimes!! Remember that we have members here from all over the world, with many different views and cultures. Political debates can turn really ugly, and really fast, and if they degrade to personal attacks and useless banter/bashing, moderator action will ensue. I want this forum to be a safe haven for technical discussions from all walks of life, so lets keep off topic discussions civil and friendly.

7) Spamming and spammers will NOT be tolerated or accepted in any way, shape, or form! Spam bots are instantly and permanently banned, and their threads deleted! The mod crew is really quick to zap spammers, we typically pop them before they even get to post. This also includes regular members as well. be courteous and not post spam. This includes links to off-site information that's not relevant to the thread at hand. Do not plug other websites, forums, or businesses in your signatures.

If you see a thread which clearly a spam bot posting that we have not removed yet, DO NOT click any links in it!! Simply click the 'report bad post' button, and it'll be taken care of, usually within minutes.

8) Account removals & closures: Since no personal information is given in the creation of your Badcaps.net Forum account, requests to remove and/or delete accounts will be declined. Any requests for removal of threads & posts you created will also be declined. The reason is the missing posts can/will leave threads incomplete and fragmented. For the threads to be of help to others later on, information can't and won't be missing. However, if you inadvertently posted personal identifiable information in a post (such as an email address, real name, or phone number), please contact a staff member. In those cases, the post may be edited or removed, at the staff members discretion.

That's about it for the rules, the setup here is pretty loose. However, if you're caught violating any of the rules above, here's what will happen:

First offense: Warning by me or a moderator
Second offense: Banning for 1 day
Third offense: Banning for 3 days
Fourth offense: Banned permanently.

If you do something really dumb, or are just a troll, I will skip the warning and the temporary banning, and ban you permanently!

The rules are pretty cut and dry... However, if you have any questions about this policy, feel free to contact me.

    Post some pictures. It may be possible to see what is wrong. Also double check the obvious things like making sure the connectors are all securely connected and oriented in the right direction.

      Re: Dim Clock LCD on Jenn-Air wall oven

      I am new to this forum. I replaced the C3 capacitor in my Jenn Air wall oven board (modelww27430p). Before the replacement, the oven would work even though there was no display to show the temp, etc. The clock displayed dimly. After the repair I can't get oven to even start, nothing beeps when I press the buttons to start a function and no clock. I tested the extra 68uf 35v capacitor (purchased from DigiKey) and get the same ohm reading with both the unused capacitor and the one on the board so it would seem that the one on the board is connected. Any suggestions on what I can do next to fix this issue? I purchased all the capacitors listed in one of the first messages in this thread. I am confident of the polarity on the capacitor as the orientation is the same as it was originally.

        Check to make sure all the connectors are connected up tightly.

          I have reconnected and all seem to be tightly coupled. I even had a friend check to see if he could find something easy that I had missed on the connections. My first reaction is that the ribbon cable isn't connected but that seems tight as well. The oven light on the exterior input panel does control the oven light, not sure if that goes through ribbon cable and board.

            Maybe you have a bad solder joint somewhere on the board.

              Re: Dim Clock LCD on Jenn-Air wall oven

              The capacitor seems tight as do the other connections on the board. I'm wondering if my problem is the ribbon cable because that connects the board to the touch panel. How do I know that the cable is well seated (pushed far enough in)? Also, is there a fuse that I might have popped because I'm thinking I disconnected or connected when the power was on once. I have attempted to attach a picture of the soldier joints. The joints aren't as flat
              on the board as the originals - is that my problem? Is there a way I can get them to flow to the board better?
              Thanks, Jackie

                Ah! no wonder why it isn't working, you broke a copper trace.

                  where is the broken copper trace (trying to learn, not questioning your response). Does this mean I just anty up and buy a new board? I'd really like a working oven even if I have to pay the price. And, how do I avoid breaking a copper trace - I want to fix my daughter's oven and not mess it up like I did mine

                    Here it is. Just use a thin piece of wire (like from a component lead) to bridge the gap there, and solder it in good. That should fix your problems!

                      Re: Dim Clock LCD on Jenn-Air wall oven

                      Some more advice that is given often on this site: Find some other electronic device that is no longer working and practice soldering on it. Remove some of the components and re-solder them back in place. Your joints should look like all the others. Once you are more comfortable with your soldering skills, then you can make another attempt on the piece that you are trying to fix.

                      Try watching some youtube video videos on soldering too!

                        There is another method I like using a thin metal pick... sometime I'll have to make that video using my special "solder cam" rig I built.

                          Thanks for the advice. I have bridged over the bad copper trace. Now the top oven is working but no display or lower oven function. I'm wondering if the ribbon cable is not seated quite right. Great advice on practicing on an old board and watching you tube videos. I'm sure practice will help. I'm not ready to give up so will try what you've suggested.

                          I'm retired now and used to have the benefit of working with wonderfully talented technical people that could point me in the right direction to fix/resolve problems. This forum is wonderful, thanks so much.

                            The solder joint on the other side of the capacitor doesn't look too good either. You might want to touch it up too. Hopefully doing that will bring life back to your clock.

                              Thanks to this forum my oven now has a display, etc. This was wonderful. Now I'm wondering how I could figure out if there is a bad capacitor in my other jenn air oven. I can't adjust the temp on that oven. That oven doesn't get as hot as it should. There are steps to input and bump the temp by 5 degree increments but they don't work. Jenn Air says I need a new control board so for now I'm setting the temp 20 degrees higher than I want to circumvent that problem.

                                  I had the local appliance repair company try to "fix" the oven. He has a good reputation and has been great on other things. He called Jenn Air when he was working on the oven because it would not register the temp increase he was trying to enter. Jenn Air tech said it needs a new board. I had installed a new thermostat and element prior to that service call but it made no change in the oven temp so I think we can rule out a bad element. The oven is in my vacation rental, when I get an open day I'll open the cover and check for bulged capacitors, etc so your comment to open it up and have a look is a point well taken. Thanks!!

                                    I also have the dimming LCD problem, Jenn Air SVD48600W model. Mine continued to get worse and worse, just like everybody else's but before seeing this forum I ordered a replacement clock module. I replaced it, it worked for about a week then that one went completely dim. The place where I bought the module sent me a replacement at no cost, but before I put it in I wanted to see if anyone knows of any other reason this could be happening. I realize the module they sent could have been faulty (it looked for all the world like a used piece; even felt a bit greasy as though it had come out of a different range rather than new). All the functions still work fine, controls the stove, everything beeps as it should, but the clock is dimmed out completely. Is there an additional board that I should be investigating?
                                    Thanks

                                      Nope, there still is an issue with the board! Have you ever soldered before?

                                      @davnjax:
                                      If the caps aren't bulged its still a good idea to replace them, they can go bad without bulging!

                                        Yes I have, but as I say I already have another replacement board in hand from the company I bought the first one from; I was just hesitant to install it for fear the actual problem was on some power supply board earlier in-line and it would just pop this one as well... at this point I'd just as soon replace the whole thing and be done. The first one I got from them was suspicious to start with, it wasn't in a box and it felt a bit greasy, so I wondered if it had come out of a used range somewhere. When I mentioned that on the phone the woman said, no, we would never d that and all our parts come new in the box. I told her this one hadn't and that it failed, she said I'll send another right out, she did and this one indeed was in a box and new. So I'll give it a shot.

                                          I am sure it is possible that there is something else afoot.... But as you said yourself, the oven works fine, all controls are functional, just a dimmed out display. This matches the symptoms that my oven had and just about everyone else that posted in this thread. I don't think anyone here claims to be an whirlpool-based oven expert, so I don't think you are going to get an alternative explanation for this issue on this forum. If you are worried about this second replacement, why not gamble $ to replace the capacitor on your original clock? You really don't have anything to lose. If it works you can send the replacements back to this shady sounding company and get the $$$ that you spent on it back.
