Kenton K Chanhassen , MN May 31, 2020 Appliance: Frigidaire Freezer FKFH21F7HWB Upright frost free freezer would not keep food frozen (Frigidaire name plate but made by (Electrolux) testing determined the refrigeration system worked but it would not defrost. Fixed it by replacing the electronic control board. Only 30 min. to fix. (See further down for effort to diagnose the problem.) Most of this "fixing time" was spent removing the control panel to access the control board that is attached to it. My freezer has the control panel located in the top center of the door. The only way to remove the control panel is to pry the panel out of the door using a thin-bladed putty knife.The instructions provided were very good in explaining the process; however, they didn't indicate that you must exert enough force to break the tabs on the panel that hold it in the door. But don't worry, there is enough friction, etc. to hold the panel in place after the repair. The vast majority of my time and effort was spent diagnosing the problem - I'm not a refrigeration appliance expert. I had been told many years ago that a frost-free freezer or refrigerator can stop keeping food cold if it doesn't run the defrost cycle regularly. Hoping this might be the problem (a relative cheaper fix), I removed all the food, unplugged the freezer and opened the door. After a day there was some water on the floor, thus indicating that there had been frost build up. I then restarted the freezer and after several hours it got down to 0* F, thus indicating that the refrigeration system worked - yeah! I tested the defrost heater and defrost cutoff thermostat which both tested good. Thus, according to the wiring diagram on the back of the freezer, the only remaining culprit was the control board. Freezer and wife are now happy. Read More... 133 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes Tools: Screwdrivers
Charles Y Branford , FL December 16, 2023 Appliance: Model LFFH21F7HWAHWJ My freezer wasn't running properly or consistently. A little backstory will help here. We've been stocking our freezer for months with various meats, game, prepared meals, casseroles, and vegetables in preparation for bad weather and bad times we hoped would never come. It was about as fully packed as humanly possible. Then one day I heard it alarming. The display was flashing and showed a slightly higher temperature. I heard the compressor try to start and kick out much like when a run capacitor is going bad. I checked the wall outlet and power cord but didn't find a problem. Regardless of the problem, hundreds of dollars worth of food were at risk, so I ordered another freezer. While I was moving the food to the new freezer, I noticed that the interior light would not come on. Normally on most appliances I have worked on, the light is simply wired from the hot line through the door switch to the neutral line. In this case, when I looked at the wiring diagram on the back of the cabinet, I saw that all power, including the light, is controlled by the motherboard. That was the answer! The motherboard had to be the problem. When the new board arrived, the included instructions were almost perfect. I used the recommended putty knife, although it took some hammering to force it between the door and the display/motherboard housing. A word of caution here - it did leave a couple of minor scratches in the door finish. It ultimately took two putty knives and a small prybar to develop enough force to break the display loose It only took a few minutes to figure out how to pry the board out of its plastic clips without damaging anything. Another point of interest - I expected to find the board attached to a length of cable when I removed it. Instead, it just pulls straight out of a mating plug firmly attached to the door. Replacing the panel required some firm bumping all around it to correctly engage the plug and but firmly up against the door The final result is that the freezer works perfectly and I have a lot more room to properly organize and stack my food.LFFH21F7 .

Guinn J Dalton , GA April 06, 2015 Appliance: Frigidaire Freezer LFFH21F7HWA Freezer died showed no power & high temp would not run at all Found that compressor was good and attempted to troubleshoot other potential problems. Once the controller apparently cleared itself and freezer came on but, when the door was opened the inside light and the compressor would short cycle, finally it quit again. Appliance Parts Pros.com website has good information or repairs and possible problems. I ask a question and they provided me with a quick reply on potential fix for the Frigidaire upright freezer model LFFH21F7HWA . The new electronic control board part# 297366300 resolved the problem and was installed in the door in less than 5 minutes by using two stiff putty knives to disengage the unit from the door.

Greg D Lakewood Ranch , FL November 08, 2015 Appliance: Frigidaire Freezer LFFH21F7HWB Control panel malfunctioning I read the comments from others and learned that our freezer was acting similarly to others. Door open errors, interior light flickering, door control panel not responding correctly when buttons pushed, etc. Finally one night the control panel went mostly dark and the freezer temperature alarm went off. A small puddle formed on the floor indicating thawing was beginning. To buy us some time, we went to the local grocery store and bought a couple sheets of dry ice to keep everything cold. Meanwhile, my wife went shopping for a new freezer while I began researching the Internet and found information on AppliancePartsPros.com suggesting the control panel was the culprit and not the mechanical parts of the freezer. So I told my wife to hold off buying a new freezer for 24 hrs while I ordered a new control panel. I received the new panel the next day and thanks to comments from others, I knew that I had to pry off the old one with a couple of putty knives. It was not easy to pry it off, but within 5 minutes I had it off and then it was just a matter of snapping on the new one. Tada' worked like a charm. The entire freezer is now working like new. For less than $150 our freezer woes are behind us. The estimate for a new freezer, with delivery charges, and removal of the old one was over $850. So this was quite the savings.
