Re: Defrost timer?
OK so you may have three things going on here. One, the condenser maybe going out or the unit needs recharging if you can hear the freezer in the first place. As such simple maintenance can prolong the units useful life. However this can be expensive. As much as half the cost of a NEW unit. Second, that the unit is simply reached its designated temperature and does not need to run the condenser to maintain its temperature to maintain that level. If so, it may turn back on when the internal temperature reaches a certain level. By resetting the defrost timer you may be getting the unit condenser to come back on and letting the frost build up. Third and the most unlikely, is there is a ground fault in the unit as sometimes the defrost timer can act as a fuse relay. Have only seen this in units pre-1970's.
