Dim Clock LCD on Jenn-Air wall oven

Re: Dim Clock LCD on Jenn-Air wall oven

I can't really tell from the pictures. But usually these things are made to snap together quickly on an assembly line. Is it possible that the tabs on both ends are what is holding the board down?

Re: Dim Clock LCD on Jenn-Air wall oven

Ok - I have a Kenmore gas range with a 316080102 control board. The display has been getting progressively less bright for the last year or so. Now it's really hard to even see what temperature settings and readings are. The clock display is really dim as well. Anyhow, I removed the control board and display to see what caps I would need to order and replace, but I found another problem. The board with the caps is kind of sitting in a frame atop the display board. I would need to remove the "cap" board from the frame to gain access to the solder points of the caps. Is there a tool or a bit of "tribal knowledge" that will allow easy removal of the top board from the plastic frame without breaking anything? It really seems to be fitted quite tight into the frame.

Thank for the info guys .

Re: Dim Clock LCD on Jenn-Air wall oven

Another Jen-Air, model SVD48600, fixed thanks to the insights posted in this thread. Thanks!

Annoyingly, it developed the "constantly running broiler fan" problem at exactly the same time the clock gave up the ghost. I know I've seen others reference that problem in this thread, and I suspect that they may be related somehow. I've posted the details of my experience in the thread on that subject should anyone else be interested.

Re: Dim Clock LCD on Jenn-Air wall oven

Thank you for your information. Picked up new Caps at radio Shack and replaced all except the one under the display. My soldering is not that good. Display works and wife is happy.

Thanks again.

Re: Dim Clock LCD on Jenn-Air wall oven

Yeah, mine looks just like that. Except that the resistor looks like it may have burned out. The solder spot on the board looked like it got hot. Probably after the holidays I'll experiment with some parts. Right now we're doing too much baking and holiday food prep to put the oven out of commission if I blow up the board while playing with it.

Re: Dim Clock LCD on Jenn-Air wall oven

There was another one a while back in this thread that was a reconditioned part and had a resistor in line with the capacitor. Does it look like this?

It is probably fine to just go back with a 68uf capacitor in the C3 position.

Re: Dim Clock LCD on Jenn-Air wall oven

My board, 71003424R, has a resistor in series with a 35v 220uf capacitor in the C3 position. Can these be replaced with a 68f 35v capacitor? Why is the resistor in the circuit? Thanks for your help!

Re: Dim Clock LCD on Jenn-Air wall oven

Thanks for this info and can you tell me what this UL stamped part is for? I found stuck to the top of the oven opening and it is magnetized and the connections have rusted.

That is a magnet commonly used with alarm switches....the pic shows the magnet half.

You might have another part in the vicinity that looks exactly like that in the pic, but with two wires coning out of one end.

What connections are you referring to? Get a pic of those connections so we can see what is going on.

Re: Dim Clock LCD on Jenn-Air wall oven

Can you see it in the oven's parts list or diagram?

Re: Dim Clock LCD on Jenn-Air wall oven

Are there any numbers on it? Can you show it from another angle?

Welcome to the badcaps forums!

I guess I should have put all of that information in my original post. So after one more peek inside the oven, here are the specs and part numbers to order from Digikey. All part numbers listed are for Panasonic FC series capacitors. FM series part number shown in parenthesis where the FC series cap is out of stock at the time of this post.


On the clock module:

C1 & C4 470uF 35v P10301-ND (or the FM series: P12400-ND)
C3 68uF 35v P10292-ND
C7 22uF 50v P10318-ND

On my oven I also replaced the two caps on the power supply/relay board as a precaution. They were as follows:

3300uf 16v P10260-ND [filter cap] (or the FM series: P12373-ND)
47uf 50v P10321-ND [the only other cap on the board]

Of course the power supply/relay board could vary if you have a different model oven (gas for example).

Please update this thread if this information is useful and you are able to repair your clock module.

Disregard. Fixed it dead. Going to buy new range.

The LED display is OK, but the beeper has been getting weaker for months. Recently the up arrow button (by the beeper) stopped working (and beeping), and a few days later the oven light and clock buttons (down arrow still working).

Of course I don't know if the beeper and button issues are related.

There are three 220Ufx35V and two 1000Ufx6.3V. The 220s measured OK capacitance in-circuit. The 1000s didn't, but one measured OK out of circuit (replaced it from my junk box - didn't help).

Does this sound like a capacitor issue? (I know I should just replace them all, but I will have to have them shipped.)

Re: Dim Clock LCD on Jenn-Air wall oven

Just wanted to say thanks to Bluto and this site! Just successfully replaced the bad capacitor for my dimmed out oven clock. I have never soldered anything in my life or, sorry to say, even knew what a capacitor was but dammed if I was going to buy a new board without trying. Read the post, watched the video, bought all the equipment and voila!
Aint the internet great....

Re: Dim Clock LCD on Jenn-Air wall oven

If the board is anywhere near heat, just replace all the caps. If they arent cooked yet, they will be soon. Caps are cheap.

I did this for my oven this year. Oven was only a few years old too.

Re: Dim Clock LCD on Jenn-Air wall oven

Check the capacitor on pins 2 and 3 of ST7.

Display became very dim about one week ago. It's very dim as you must have lights out or hand over display to tell it even works. Reading forums I learned that C3 capacitor is likely the cause but my model is newer different. I planned to replace the capacitor anyway but was unable to find a 57u rated 250V locally. I went to a TV repair store to see if they stocked them and they put a quick tester on them (while still on circuit board) and they said “that's not the problem”…. I had him put the same tester on C3, C6 and C7 which all tested good for what that's worth. So now I don't know if it's a waste of time to still replace them or if this is a different problem. Advice?

did they test them with the board physically hot? if not, replace them. it could show up when the board warms.

Re: Dim Clock LCD on Jenn-Air wall oven

Thanks .... just repaired my Jenn-Air SVE47600WC using the info in this forum. I had plenty of experience with soldering components so it was a breeze. My solder sucker makes removal simple. Those without experience should keep in mind not to use too much heat as it will damage the traces on the board.
