IceMaker Stopped Brand: General Electric Model Number: tfx22zr Age: More than 10 years Hi Folks,
I have an icemaker that stopped working. I'm looking for ways to troubleshoot it.
The Story:
Last week the dispenser started only giving crushed ice. So I started to track down the problem. I initially thought it might be the selector switch on the front. So I took out the board and checked the switch. The switch seemed to be fine, contacts were opening and closing. So I went on to the freezer. I had to take the icemaker out to get to the back of the unit. It turned out the solenoid that operates the little gate at the crusher had come apart. I put it back together, reinstalled the IM and plugged the fridge back in. I got some ice out of it and the gate was working again. I noticed a funny smell in the freezer, but though it might just be from the thawing that had occurred while I was working on it. I noticed that the IM was cycling. A few minutes later I came checked it again and the IM was still cycling. The heater was on on the IM and was pretty hot. That was were the smell was coming from I think. I just figured it may have kicked into a defrost cycle or something from having the power off.
Now the unit is dead and does nothing.
I don't know why the heater stuck on.
Can someone tell what I should read at the IM plug. I wanted to see if it is getting power at the socket.
There is a small white device attached beside the the heating element, may be a thermistor and may have opened from the heater sticking.
Can someone give me pointers as how to troubleshoot this. I am very mechanically, electrically inclined. An engineer by trade.
Thanks Guys,
