Freezer not freezing. Fan not running, compressor is warm to the touch. Any ideas on what to look at first?

Not having the model number makes it difficult, assuming the fan that's not running is a condenser fan by the compressor then check for power going to this motor to see if it's bad... If it's the fan inside the freezer then it's possible this motor is bad or will not power up unless the evaporator is cold.. Which would bring you back to the compressor, is it running, is their a clicking sound indicating the compressor is attempting to start? Clicking sound may indicate defective relay or compressor... Obtain a replacement relay (AP3149131) to see if the compressor will start up... Another option is a relay combo (AP3540659) that includes the overload and a capacitor... That option is assuming your compressor is a 1/4 or 1/3 HP one... Hope this helps, kooler

You have a bad defrost timer. Your old timer is probably a 21 minute defrost and 8 hour compressor run time. I would replace it with a GE timer p# 9x330 a much more reliable timer.Or you can go with a universal timer (electronic) P # EDT10
Per my catalog they all look the same and should mount in there, the electrical connections should be at the same places as the old one, but I usually verify with an ohms check.
