repair people said they want to replace defrost timer 45.00, defrost heater coil, 30.00 and the defrost thermostat 20.00 plus 60.00 service call, plus 1-3 hrs labor at 60.00. I went ahead and ordered thru you all 3 parts they were going to replace and i will start with the timer first and see if that takes care of the problem. I have already defrosted the coils and turned back on and already 40 degrees in the refrigerator part. any comments would be appriciated.
