My freezer seems to be going into extended defrost. Ice melts then refreezes.
Just replaced evaporator & thermistor and control board. Worked great for 24 hours, then started defrosting again? What next?

Does everything shut down during defrost? No fans running or no compressor?

I don't believe that the fan or compressor run during defrost. Will have to verify when it defrosts again. Last night, hubby said the freezer was *very* warm.

Freezer went into defrost again. No fan or compressor running. Back panel of until where coils are was warm to the touch. Everything is wet and drippy. Held door open a while, the evaporator fan started going...warm air. Then compressor? kicked in, cool air began and back cover panel was cool.

You probably have a shorted defrost thermostat clipped to the evaporator coils, rather rare. It's a special one, just look it up on this site and order it.

Replaced defrost thermostat, and problem solved...almost. Defrost issue is better. I haven't caught the unit in defrost to actually see bow warm the freezer gets inside, but from appearances, the amount of frozen drips inside the unit is reduced. However, my in-the-door ice dispenser is unusable. The motor defrosts then refreezes, making the unit unable to move. If I defrost it with a hair dryer, cycle will repeat itself. Also, the ice in the tray freezes together into a solid ice monster. Am I at this point having to face the reality of retiring this beast, and buying a new one?

Freezer is currently in defrost. Most items are still frozen/partially frozen, but walls are dripping :(
