H K for Model Number LFFH21F7HWB Door Ajar alarm sounds. Door is shut and well sealed. Alarm is reset. Sometimes will stay off and other times the door alarm will start again in a few minutes. Temp at 0, Freezer working normally. I've unplugged for a few minutes to do a reset. Have same issue intermittently with another unit LFFH17F7HWD Any suggestions? Is a control board difficult to replace?
Answer HK, First thing is check or replace the door switch 297243800 and check for loose connections, check the wiring harness at the freezer door hinge and make sure the door closes and seals along the bottom of the door and activates the switch. If the problem persists replace the control board 297235200. The control board is relatively easy " To remove the Precision Set control assembly: 1. Disconnect power to freezer. 2. Using a small flat bladed screwdriver or equivalent tool, carefully pry under the bezel until the retaining latches release from the door assembly. Pull control assembly straight out to avoid damaging the electrical connection wire prongs. To install the Precision Set control assembly: 1. Push control in gently with the palm of your hand. You may need to slightly adjust the bezel position up or down to align connector pins. 2. Gently push control flush to door with palm of hand." Read More...
