I have a Magic Chef Model No. CTN1511GEW problem is frost build up. I have tried everything I can think of and the frost build up continues. I have defrosted the freezer using a hair dryer but careful not to heat it at any section of the frost for too long. On reconnecting the electrical cord to the outlet the refrigerator works perfectly and runs for 6 hours then shuts of. I don’t know how many minutes before restarting because the compressor is very quite and I don hear it. But it stopped again after 3 hours and works normal after that but after 3 to 4 days the frost starts building up.

I don’t know if it is the defrost heater, defrost thermostat or defrost timer. I know how all these items look but I cannot find a defrost timer. I don’t know what can go wrong on a defrost heater because it is simply a rod covered with clear plastic.

Also there is a condenser in the compressor compartment just left of the compressor but nearer to the wall of the refrigerator. I have seen a printing in a repair help “Change suggested”. It did not say change if bad. Why such a suggestion if it may still be good.

Also how can I test the defrosters for efficiency?

Thanks for your help.
