Product review (5 stars): Let say it wasn't fun babysitting the fridge
Upon returning from an overseas trip, I knew something was wrong with my Maytag Plus (Model MSD2456GE*) refrigerator.  The compressor was making a strange sound and the frame between the doors was quite hot to the touch.  I pulled the fridge out, removed the cardboard panel and noticed that the condenser/cooling fan didn't operate while the compressor was running.  I had to manually start the fan by giving the fan blades a quick turn.  While waiting for the replacement part to arrive, I kept a large box fan running and pointed at the condenser/compressor.  Let say it wasn't fun babysitting the fridge.
The replacement part (Whirlpool 61005323) is an exact replacement for the Panasonic UDQR003M2 fan motor.  It has been approximately 3 weeks since I replaced the part.  The fridge has been operating normally since.
