James B for Model Number LFFH21F7HW All of a sudden my freezer started with the HI Temp and Door Ajar warning, Temperarture was going up. I read on the internet where this could possible be a defective switch. I bought a switch, but wrong one, for manual model,. I went ahead and replaced the switch with the round one. I closed the circuit on the switch by taping the switch closed. Unit worked great for a couple of days. My wife went to clean the front door and the gasket, while freezer was closed, and immediately the HI Temp and Door Ajar light came on and temperature started rising. Any suggestions.
Answer James, The most likely cause for the door alarm and hi temp alarm to go off would be a faulty control board. The control board part number is 297235200. Read More... Answered by AppliancePartsPros.com | Monday, September 1, 2014
