KRSC503ESS00 kitchenaid refrigerator freezer is not maintaining temperature. It melts everything in it then refreezes. Technician came out and opened inside panel. Said coils looked fine and offered to replace temperature censor explaining that this is most common problem. He didn’t really diagnosed the problem but just guessed. Kitchenaid paid for that and it didn’t really solve the problem, but it seems like it was running better for a few months. Could that be defective or not lasting long temperature sensors? We are not even using ice maker cus it melts everything and all the water is coming out and refreezes inside. I don’t want to pay 109$ for technician to come open the freezer door and guess again. It’s a two year old fridge and I started to notice this problem in less then one year
Hi @irinka , What are the actual temperatures in the freezer and the refrigerator? Use an appropriate thermometer to check what the temperatures are when the compressor motor has been running for a while. The normal freezer operating temperature is 0 F (-18 C) and the refrigerator temperature is ~36-39 F (3-5 C) Is the compressor motor running when the water has melted? You say it melts and then refreezes. This could be a faulty freezer temp sensor (part #4 freezer liner parts) or a faulty control board (part #20 cabinet parts) or perhaps the wiring in between. When the problem happens check if the compressor is running or not and if it is not running how long it stays off before restarting. The refrigerator goes into an auto defrost cycle once every 8-12 hours (depends on the manufacturer) to melt the ice build up on the evaporator unit in the freezer compartment. The meltwater is allowed to drain away to the evaporator pan, outside under the freezer compartment and to evaporate. During the auto defrost cycle time period the compressor motor and the evaporator fan are stopped and the defrost heater is turned on to help melt any ice buildup. The auto defrost cycle should only last about 15-20 minutes, which is not long enough for any properly frozen food to even begin to thaw let alone melt. The temp in the freezer compartment is allowed to rise to ~32 F (0 C) to aid in the melting process. When it reaches ~32F (0 C) the sensor relays the information to the control board to stop the auto defrost cycle and to turn off the heater and restart the compressor to cool the freezer and fridge back down to the set temps. Obviously it takes a bit of time to get back down to the set temperatures
