Check that - the relay buzzes very slightly when I do the L1-test jumper.  I'm heading out to buy a capacitor and zeners.

A good capacitor may be hard to find..

a cheap one is OK if it's the right voltage...

zeners are optional

Are your Zeners just to prevent someone shocking themselves if they don't discharge C2?

I'll post pics of my repair job, if it works (and if I can find the caps!).

mentioned in schematic Maytag ADC PDF  on I posted on page 3

may have 120v accross 50v capacitor if Q1 is off and residual magnetism keeps K1 on for any length of time

Ah, I see - possibly the culprit damaging C2 already, eh?

Have you sent this in to Maytag and asked about your solution?

possible... or the humidity...

Maytag... no, I didn't bother...

they wouldn't admit to anything wrong....

although the newer ADC boards are different design...

and there's a 3rd party model (with diagnostic LED) available on eBay..

Replaced only the C2 capacitor - and that, only with a 22 uF 35V - couldn't find one in 50V.

Put the board back in and did the L1-test short - compressor cut off, heard the heater heating up (water drips were hissing).

Things to note:

The capacitor removed was a 22 uF 63V piece.  So, if it cuts out on me again, I'll buy that one.  In fact, I'm going to order the Tantalum C2 and C3 in 63V.

How did you put in your Zeners?  Got a picture?  I bought them but didn't put them in.

ETA:  Woohoo.  Heater is most definitely on.

If you can find Tantulums, that size, at that voltage,... at  a decent price ..

(originals are axial leads)

shouldn't need much more than 35v if the zeners are installed...

(3) zeners hard-wired in series, right across the big capacitor...

So you just soldered the ends of the zeners together and then onto the C2 leads?

I just put the Zeners on (and an ugly solder job it was - I wrapped electrical tape around them just in case).

Works good!

Gentlemen, polarity is key.

And though I still can't find why I might have put the zeners backwards (stripe on Zener is cathode, matched to positive of C2), I think I did because R17-19 were really damn hot and now defrost won't work again.

I'm going to get another C2 and try that, but the Zeners are off for now.


Ah well, I've saved a couple of hundred even if I have to buy a board online.

I couldn't see the zeners because of the tape ...

It is a crazy board design.

The 5v ground (and the board common), is connected to 120v L1 HOT side of the line.

C2- is one way and  C3- is the other way...

(caps are marked with - , not +)

They could have mounted them the same way and changed the circuit on the copper side of the board.


If the zeners were reversed (all of them) it shouldn't have ruined C2...
nor anything else I could see...not even the zeners.

I didn't think so either, but they were sure dumping current, when I pulled the board (maybe 3 minutes) the R17-19 were pretty hot.

I'll check defrost tomorrow.
