Not Cooling The Compressor and the defrost heater opperate at the same time. The timer has been checked and the timer opperates okay. (Defrost fuse had been changed due to being overheated.)

The defrost heater and compressor can't operate at the same time unless the timer is bad. It disconnects the compressor and evap. fan during defrost cycle. Not sure what you call the "fuse", are you talking about the clip on disk that's on the evap. coil? If so that is the safety "fuse" as you call it to "open" and kill power to the heating element if the element gets the interior too hot. Usually water seeps in then freezes and pops the expoxy plug up thus breaking the normally closed power loop. If you have power going to the heating element (and it's hot, etc.) AND the fan/compressor is running then it has to be the defrost timer that's bad. There's just no way the heater element can be getting power at the same time the compressor is getting power unless that timer is bad (or a major short in some wiring somewhere). If you unplug the timer what effect does it have on your system? Let us know, this one sounds interesting...
