@@bensappliancesandjunk so what do you use to get the capacitors off the board ? What desoldering techniques do you use ? I’m not so much into appliance repair, but have worked on electronic component level repair on and off for years and still have my Pace rework station. Keeping it running isn’t cheap, but it makes life so much easier for swapping out parts, both through hold and SMD. It was a big big outlay for me 30 years ago, but it paid off pretty quickly, as boards I used to work on were thousand dollars plus in todays money How much support is there for getting these appliance boards repaired, and are there third party controller boards that you can drop in as a replacements ? Would there be a market for those sorts of things ?

@@MidlifeRenaissanceMan For cheap solutions, we use a $40 de-soldering pump. Techs that do board repair more frequently than us tend to use Hakko FR-301's. 80% of repairs are caps or relays. When it goes beyond those into resistors, triacs or logic boards (especially), techs shy away from them because you get a lot of parts bloat at that point, whereas about 17 types of caps and maybe 20 different relays will fix 80% of appliance failures with first call completes.

Yes I like the ESR meter, be cautious to those trying to repair a board as those newbies. Larger 200 volt, 400 V capacitors have the ability to send you flying into the next room or kill you. Handle circuit boards with care and discharge the cap by shorting it especially if it is a high voltage cap.

Holy crap. Is that huge pile of circuit boards in your video yours? Do you plan on trying to fix them or do you just keep them for parts? I would buy them all if you were somewhat close and shipping wasn’t so expensive. Also, the guy who designed the circuit in the ESR meter is named Dave Miga. He’s the owner/operator of electronic design specialists. He invented the “cap analyzer 88a”….. and then his circuit was widely copied. If you get a chance to snag one of those on eBay, or if you purchase the parts kit and build it yourself… I highly suggest it. Another device that he invented and is worth its weight in gold… it’s a device called the “leak seeker“… . Even in my metrology lab sitting on the bench next to High end test equipment that is all NIST traceable/calibrated equipment… I still use both of them almost every day. And find them just as useful then all my fancy metrology equipment. And when troubleshooting they are my go to!

I am thankful for guys like you. I like to fix things myself and your videos help alot.

It would be a good idea to upgrade the caps while you are in there as well w/the poly style caps, they are more expensive but will way outlast a standard electrolytic.

Love your video! I was all excited to try and repair the control bd on my GE Harmony washer using this method. Unfortunately I get the module out and find it is emersed in some sort of clear rubber. 😥 The control module is WH12X10282 and even a used one goes for min $150, and this is for an old used part that may not even work! I found this video about removing these coatings, and even with all sorts of fancy specialty tools (that I do not have), it looks like a nightmare. If you are curious just search YT for "PACE Rework and Repair "Conformal Coating Removal". I don't think it is worth putting that kind of money into a machine this old. Sadly, unless someone has an idea, I think I have to buy a new washer.

My Whirlpool Top Load washer keeps failing for the pressure switch that is built into the control board. It just stops but all functions seem to work. If I restart it on rinse or spin it will always finish the job. But from start to finish it almost never finishes in 1 go. Any recommendations on where to start looking on the board? Since it's not really a power issue and everything seems to be working. Ill start by looking for the obvious and then that specific area of course.

This was VERY informative! Thank you!

You may have to dig the probes into the solder joint. These boards, at least the one in this video and mine, have a waterproof coating on them. That's what that shiny coating is that you're seeing on the board in this video.

Hi, the answer is "Kind of" Higher-end multimeters can do capacitance/ESR tests. However, they generally CANNOT do it on-board. You'd have to de-solder the capacitor, then test with the multimeter. Even some/most ESR meters can't do on-board testing, either. As far as I know, that technology/ability was basically invented and pioneered by BK Precision and the GME knock-offs, or so I've been told. So sadly, you do need the special meter to hardcore capacitor tests quickly and easily.

Another note, which isnt in this video but in the Frigidaire Stove video: Relays are similar, but can also be different. Relays switch power on/off, so if something isnt getting ANY voltage, its usually a bad relay. Thats far more typical on high-voltage appliances like stoves and dryers not working right. There can be physical evidences too on relays and caps, so we look for that first. Boards follow an 80/20 rule: 80% of your problems have 20% of the solutions, so keep it simple. Another BIG BIG thing is joining a good group that documents these fixes... There are very common failures with electronic boards,and if you know what they are, you canspot them and fix it fast.

What would cause the control board to randomly select modes on its own without actually touching any buttons. ? I took the control panel out it and it is not wet. It's like some days the buttons work. Also some days it turns on and starts selecting modes by itself.

Cheap capacitors fail in everything with a circuit board. A great place to get caps is Mouser Electronics or Digi-key. Use Nichicon or Panasonic caps, they are the top brands. I would stay away from cheap capacitor kits as those are most likely floor sweepings.

is it a defective capacitor or did something cause the capacitor to go bad????....if you put in a new capacitor, will it blow again????

I do not have any PERSONAL experience with it. But in the board repair tech groups I am in, quite a few use it because its almost $100 less (now) than the BK881 and all I've heard is great feedback about it. My experience is that the GME is the "Minimum" you want for board repair and you should avoid the Chinese cheap-o's out there. The GME is made by a Taiwanese manufacturer, and I believe the build quality is good from what I've seen on the internet from fellow techs.

Because standard Dmm's only measure DC resistance, which in any capacitor will be over limit. The esr meter measures by sending an ac 100Mhz signal through the cap, effectively measuring the equivalent series resistance. Basically the reason is because Esr and DC resistance are not the same thing

@bensappliancesandjunk

It was on accident. That mode tests DC-related resistance @ 0hz, while the ESR tests AC resistance. There are a few components on the board that DCR would be valuable to use on, such as non-inductive resistors (not caps). I accidently used the DCR (which is automatically employed when needed). I edited that out but it sounded like a tornado siren. That threw me WAY off guard. More or less, its a bonus test mode, but we've never used it to fix anything, and the DCR will just use ESR until there's a non-inductive coil.
