Whirlpool 4210463RW Refrigerator Condenser Coil Cleaning Brush OEM Part

Replaced bad condenser motor

We Googled the symptoms, which brought us to your website. Based on the recommendations, we purchased a compressor starting device kit, defrost thermostat (just to be safe), and a condenser brush. We cleaned all the coils, replaced the compressor starting device and defrost thermostat using your instructions and video. IT WORKED!! We are on day four and the refrigerator and freezer are working! Thank you so much!! We thought we were going to have to purchase a new refrigerator and that would be $1500-$2500 to match our current kitchen appliances.

Replaced defrost thermostat. Apparently got lucky though. It would have been nice to know the On/OFF temperature specification for the thermostat. I ordered the thermostat after verifying the heater coil resistance was not open (measured around 25 ohms with cheapie DMM). I also forced the defrost timer into defrost and verified 110V to the heater / thermostat. I timed the defrost timer which cut-out after about 30 minutes which seemed appropriate. The thermostat would not close after soaking in ice water for about 10 minutes. After replacing the thermostat, I immediately forced the timer into a defrost cycle, and still no heat from the heater. Bummer! I removed the new thermostat and soaked it in ice water for several minutes and it still wouldn't close. I was ready to condemn it like the original, but decided to reattach it to the evaporator tubing and after about 5 minutes of allowing the evaporator tubing to cool it to below 20F, it finally closed. I then reconnected the thermostat and forced the defrost timer into defrost again and wallah, heat and defrost worked! I was very pleased with the speed of package delivery. The condenser brush worked nicely to remove most of the 10 years of built up dust on the coils. The refrigerator has woked nicely now for several days. Hopefully, it will run for several more years. I have a similar refrigerator 30 years old that continues to run and run although I've had to replace the defrost heater coil in it three times.

Brushed coils.

Through process of elimination, I was able to rule out the filter, filter head, and the water inlet valve. The water storage tanks behind the crisper and deli drawers were frozen. This led me to check the heater which I tested, found bad, and ordered a replacement from Appliancepartspros.com. Replacement of the heater was very easy; troubleshooting that it was the problem took a fair amount of time. The only negative was that the part was not shown in the parts diagram on line for this model.
