    Motor Run Capacitor in AC unit

    The hot summer days from the heat wave around a month ago here in southern california took its toll on my Air Conditioning unit. I tried to turn it on a few days ago as usual..., but the unit would not start up. A quick call to a friend who services AC units got me back up and running again. There was a bad motor run cap that was obviously bulging



    Replacement cap was bought locally for around $15, MUCH cheaper than calling some random AC repairman from the yellow pages. Just though I would share this experience with you guys.

      My brother had the same problem with a large window unit he uses to cool his ranch house.
      Ludicrous gibs!

          in a good season i can fill a 5 gallon pickle bucket with motor caps failed like that just from window units i rebuild to sell.sometimes they blow up or spit out the terminals.

                  Are that AL elektrolytic caps? metall paer should not bulge that way, but may be a litle expensive at that capacity.

                      iirc they are paper/oil dielectric.

                          Might tell that to the man at the locan junkyard.
                          My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

                              Motor run capacitor physical size vs voltage rating & measurements?
                              by Per Hansson
                              (TL;DR skip the first paragraph)
                              I encountered my first dead motor run capacitor at a customer this week.
                              For some fields I guess it is a very common occurrence but the usual way for industrial machines here is to use 3-phase motors.
                              (Unless a servo motor makes more sense that is).
                              But for some reason this 3-phase machine uses a 1-phase motor for its liquid coolant pump.
                              The pump would run but sometimes trip the 10A breaker.
                              I monitored it starting and stopping for over an hour until it finally stopped in a specific spot between its windings:
                              Then it could...

                              Air-conditioning unit power supply failing to power up
                              by Gjackson
                              Hi all, I managed to narrow down which PCB was causing my Haier AC to throw out an E7 error code (E7 indicates that the indoor unit and outdoor unit cannot communicate). I found that the outdoor unit power board which gives 5v and 15v to the outdoor unit module board fails to fully power up.. The power Led starts to fade in incredibly slowly and the 5v and 15v power buses jump around like crazy and never reach their required voltage. I unplugged the module board from the power board and the power board powered up fine! It had a steady 5v and 15v out and the power LED came on instantly and Bright....

                              Hi people, I hope this is the correct spot to post this, I'm new to the forum.

                              I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

                              I hope these photos make it clear which component I am referring to:
                              (yes, the soldering is a bit botched from removing the blown one, I know)

                              I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

                              If I replace with inferior capacitor, Is it No harm to other IC components at all?
                              by chth96
                              I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
                              Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
                              It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
                              So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
                              I know that these capacitor will not last as long as nichicon capacitor...

                              How can I test non-polarized capacitor?
                              by chth96
                              I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
                              I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

                              And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
                              I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...
