i have an electrolux fridge model wwtr1802kwe. When my compressor runs my freezer freezes to -17 or so. After it shuts off over time my freezer goes to like the fridge temp of like 35 This is with the temp set to coldest. So like a fridge and freezer at same temp. I changed the temp control thermostat. I set temp to normal after being unplugged for a few days and it started , ran and cooled normally and after a while freezer warm again. i turned knob to coldest setting and compressor started and freezer cooled ok until over time freezer now warm again . Condenser and evap fans run and coils are clean and no ice in evap coils. Could this be a starting relay controller or starting capacitor problem. The fridge is about 10 years old and i have another the same that works fine after 10 years. They are not really expensive fridges so i dont want to spend a lot to repair. any thoughts would be appreciated..
Hi @ehrmy1 , There may be a problem with the bi-metal thermostat (aka defrost thermostat), part #21 -system diagram. The bi-metal thermostat is used to end the defrost cycle so that the defrost heater is turned off and the compressor and evaporator fans are turned back on again to drive the temp back down to the set temps. The defrost cycle occurs approx once every 10 hours and lasts for about 20 minutes. What happens is that the compressor and evap fan are turned off by the defrost timer initiating the defrost cycle and the defrost heater is turned on to melt any accumulated ice from the evap unit so that it can drain away to the evap pan under the compartments. The temp in the freezer compartment is allowed to rise to aid in the melting process but usually it doesn’t get any higher than 32 F before the thermostat operates, as you don’t want the frozen food to even begin to thaw.The temp near the thermostat is higher because it is above the heater Here’s a video that shows how to test the thermostat which may help. If it is determined that the defrost thermostat is the problem there are other suppliers online that may suit you better as I only linked the above supplier to show the location of the part and also the cost. Just search for wwtr1802kwe parts to get results. If it isn’t the defrost thermostat it may be the defrost timer part #23 -shelves diagram
