My freezer keep frosting up behind the freezer panel and I'd have the repairman come out and fix it. Then I found the instructions that came with it. It tells how to push the control buttons to check the various circuits. It runs through a complete check-out of the systems INCLUDING the defrost cycle. In effect, I was forcing it to go through the defrost cycle, which cured the problem.
Allowed me to stop calling the repair man when it happens, which is way to frequently. Mostly when we have company and the door is opened too much.

• My Maytag MSD2556AEB was frosting up; from this thread I felt it needed the ADC#61005988
• Ohm test showed about 25ohms
• Replaced ADC and still frosts up, fridge never shuts off.

The fridge fan used to stop, but while I was waiting for the part to come in we were defrosting it often and we had to turn it on and off by hand (perhaps the blow dryer on high broke something else). It never seems to defrost nor reach a temperature that it is happy with. The fridge gets cold without a problem, we are just manually watching the temperature.

Is there something else it could be? I'm not sure what to check next. And yes I did buy my part of ebay (I know probably a mistake, but wasn't confident enough to drop $60).

On a side note I was never able to get the ice-maker to work. I had to replace the pump in the back (the prior owner let it freeze and crack), and now the water works fine. I've checked the wires and they are correct. The tubes work and nothing leaks; and if I switch the wires I can use the 'water' button to make ice, lol. I doubt it has anything to do with this.

Its likely the defrost board is bad you got from ebay.

To make sure your defrost board is the problem:
Check your defrost thermostat and defrost heater, you will need an ohm meter to test for continuity on the defrost thermostat(WHILE ITS FROSTY) first. It should read 0 ohms.

Unplug your refrigerator first!

Here's the defrost heater/thermostat assembly for your model:
Manufacturer part#61006198 is RepairClinic item#1021857


Let us know what you find.

Thank you for the quick response. I spent a lot of time troubleshooting the fridge yesterday and it appears the ebay part was bad. The Ohm test showed up at 0.1 ohms and looks good for the heater. The volts are 120 at the control board and appear to send that to the defrost heater when triggered (with the old board). If I understand it correctly the defrost thermostat is in series with the defrost timer - so that the timer tells the coil to heat up, but it will only oblige if the thermostat agrees with that call.

Anyway, the new board was giving me different volt readings, and trying to override everything and trigger the defrost heater on my own wasn't working (not sure if I can). The short end of it is I'm confident that your part would fix my fridge - worse case I would also need the defrost thermostat part; however we went and got a new fridge. Even if we were to fix this fridge, we don't trust it, it bothers us that the ice-maker doesn't work - and it isn't helping our electric bill all that much. On the plus side I did learn a lot.

Ok, yes, sounds like you did the right thing in getting the new refrigerator.

Yes, I've always been very against getting appliance parts on ebay, I remember a member a few weeks ago that got two bad dryer motors from ebay.

Hope you like your new refrigerator.

Jake
