I have a MZD2766GEW refrig. I noticed the center mullion was very hot so I cleaned the condensor coils and noticed the condensor fan is not running when the compressor is on. It's getting about 120 volts and if i give it a nudge it will run until the compressor turns off. I pulled the fan motor and am getting resistance in the 30 Meg Ohm range between the two leeds. I've got a fan running on the condensor and compressor while I'm trying to solve this issue and the fridge works fine this way. I just want to make sure the fan motor is my problem before I buy a replacement. Thanks!

Also called mullion heater or yoder loop(the center panel)There is some designed heat to keep this area from sweating.....Too much(hot) may mean the compressor cooling fan that also moves air across the coils (condensor coils) is stopped Romove back panel to check, also check the coils that are on the very bottom for good air flow, fan moving air can cause a accumation in the front of coils of pet hair over time.... Hope this helps......
The condensor fan cools the condensor coils. If it is running this will cause a no cool situation. Also, if the condensor coils are plugged with dirt that insulates the coils and causes a no cool situation. These things will make it so the freezer isn't cold enough to freeze water so the icemaker will not produce ice. As far as the door edges getting hot. A condensor line runs thru the cabinet between the doors and this is called the mullion. If it is too hot this is a good indication of a bad condensor motor or dirty coils. Clean the coils and check the status of the fan motor and let me know what you find and we will see if we need to go further.
As the weather is getting warmer for many people their freezer and/or
refrigerator do not work right because of a dirty condenser coil...there are
also many other things that can go wrong. If you are hearing a clicking or
buzzing then check out the last two tips.
If your refrigerator is running but warm, then…
Check out this tip that I wrote about that... it is a great place to start
trouble shooting your unit...and something that you can do rather then calling
a repair person to do a simple thing for you...
Pull the refrig out , and remove the back panel . Is the compressor running ? Is it hot ? Is the fan cooling the compressor , running ? If the compressor is not running , the piece on the side , with 2 or 3 wires going to it , is bad . If the fan is not running , replace the fan motor . The part number for the compressor piece ( overload/relay kit ) is 12002784 . It is easily replaceable . If the compressor is running , check the square black coil box ( condensor coil ) , to make sure it is clean . Is clean , check the fan in the freezer , to make sure it is working .
you have the power adjust, summer controls, whatever its called for your model, and manufacture
but its normal, this is the YODA LOOP
or the MULLIAN htr.....
it is very normal for it to be hot to the touch, this is actually the heat that is being withdrawn from your box, in the older models, unless the paint is flaking i would not be overly concerned
when the center mullion is hot then it means your units condensor fan motor is out. the fan is located by the compressor. this fan keeps the condensor coils cooled off. if the fan is not running then the unit vents through the cabinet.
light falshing is normal, the strip between being hot is not though, remove the kickplate from under refrig and vaccuum the coils, pull unit out and clean behind, while there make sure that the fan adjacent to compressor is running(when compreessor is on). clogged condensor =hot mullion stip. not a major problem
This area is called the mullion and should be a little warm so it doesn't sweat. If it is too hot then two things could be the problem. 1. The condensor is plugged (dirty) and needs to be swept out. 2. The condensor fan motor is not working. This cools the condensor coils and is mounted in the back of the fridge behind the bottom panel.
