This freezer gets to around 26º F during the defrost cycles. Does this indicate a problem with the bimetal sensor? The timer was replaced under warranty (out of warranty now) when it was not getting below about 30º F at all. Now it gets to 0º F but then cycles through the higher temps in the mid 20s. I am afraid that this is too warm to be safe for frozen food.
Answer Hello Stu,
You need to make sure the condenser coils, (hot coils), are not obstructed by lint or any other objects that can prevent air flow, (like paper bags, boxes, etc.). You should also check the frost pattern on the evaporator coils (cold coils). The frost on the cold coils should form at least 3/4 of the way down from the top of them. If the frost on the top is thick at the top, it is usually an evaporator fan motor issue. If there is no frost at the bottom at all or there is an ice ball where the lines come into the compartment, there is most likely a sealed system issue.
