Here are your parts
Replacement parts for DRS2362A models | AppliancePartsPros.comIf compressor is running pretty well all the time and it is not freezing you could have a defrost problem or low freon.
Also be sure that the fan in the freezer is running. If not this may be your only problem. Be sure that the compressor is running when you check it as it is turned off during a defrost cycle as is the compressor and it's fan.
If the fan is OK
First remove the evaporator cover in the freezer so you can see the coils.
Not do not let them de-ice.
If they are heavily iced/frosted over you have a defrost problem.
If yes.
Manually force a defrost cycle by turning the defrost timer cam till the fans and compressor turn off.
Looks like your timer is behind the kick plate.
Now check the defrost heater to see if it is on.
Be careful you do not want to burn your fingers.
If the heater is on then the timer needs replacing, re: it is probably stalling during it's rotation so is never getting into a defrost cycle.
If not on.
Unplug the unit.
Remove the wire for one side of the heating element (Item in Section ) from the wiring and measure it for continuity, usually around 20 ohms or so.
If the heater is OK
Remove one wire to the defrost thermostat (Item in Section ) and measure it, should be 0 ohms when frozen. Note that it opens just above freezing so must be frozen to check it. Also inspect it, if it is bulged at all replace it even if it measures OK.
If both the above are OK then odds are the defrost timer contacts are toast.
Best way to test this is a live test to see if you have 120 volts across the heater/defrost thermostat combo.
If the coils have only one area with frost on them, usually where the freon enters the coiuls then you probably have a low freon situation.
