You have a clogged drain in the freezer backing up to the air return vents.
Pull freezer panel to expose drain area. I use a turkey baster to dump boiling water in the dran area which is in the back wall in the middle.
Keep pumping and removing hot water till the drain runs clear.
If you have a metal defrost heater, run a heavy gauge copper wire around the heater and down the drain. Will keep drain from freezing. |
