Dennis H Many , LA December 15, 2015 Appliance: Whirlpool Refrigerator ET8MTMXKQ00 Whirlpool Refrigerator Et8mtmxkq00: My refrigerator stopped cooling i could turn the cold knob off and back on and it would cool until it cycled off. How to replace Cold Control. I used the model number to find the thermostat cold control switch on Appliance Parts Pro's web site and ordered the part. I had to remove a bracket that was on the new control unit because it was not correct. The switch was correct but the bracket and the sensor were different compared to the original control switch. The cover housing that held the switch was retained by one screw that I removed with a 1/4 nut driver. The cover was hinged at the other end allowing me to remove the old switch while the wiring and a control board stayed in place. I installed the switch after removing the bracket just as the original switch was. I attached the original knob that was removed from the old switch. I plugged the refrigerator in after the screw was put back in the cover and tightened lightly. The refrigerator came on immediately and is cooling like it should. 13 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
