my evaperator fan was not working so I replaced it. only to find out that the defrost timer was bad. so I replaced it and it lasted 2 days and now its bad can you tell me what could be knocking them out ? I have been told the defrost thermastat is letting the heater run to long. Is this the only thing that can knock it out if thats even it?

I don't think the timer has anything to do with it. The side by side amana ref defrost thermostat is wired in series with the evaporator motor. Thats most likely the problem. The timer had nothing to do with it. If you look at you defrost thermostat it will most likely be bulged out, replace it and I thing it will work.
