I am having a defrost issue with my GSS25SGMCBS. I jumped the terminals at the main control board and verified that the heater does operate so I replaced the control board. The unit used to freeze up every 3-4 weeks. Since replacing the control board, the unit has operated about 3 months before freezing up again. I currently have a single 12'' heater and was told by Derrick via the online chat that the double 9'' AP4355467 upgraded element will provide me a better defrost cycle so I went ahead and placed an order last night. This morning I have been doing a little more research and it appears that the double 9'' unit will not fit in my unit. Can you confirm this? Also, what else should I check/replace to ensure I get adequate defrost? The unit operates/cools just fine in between freeze ups.
ANSWER Hello Dennis,
There are temperature sensors WR55X10025 in this design that can cause issues. Three of them to be precise. One in the fresh food compartment, which normally doesn't give a problem, one in the freezer compartment at the very bottom on the left side, and one in the evaporator compartment at the top left of the evaporator. These last two are the ones that are of concern. (All three have the same part number. If you replace them, put some grease in the butt connectors or wire nuts to prevent moisture from corroding the connections and causing a repeat of the failure).
The defrost heater WR51X10055 that I would use is the first one listed as it is not a "modified design" that has been put on the market to see if it will work.
