Hello, If the heater isn’t working, then you would be experiencing an ice build up in the freezer, resulting in poor temperatures because of the reduction in air flow.
hello, I’ve just seen your post further down the board. if what you’re experiencing is ice on the base of the freezer, then it’s more than likely that the evaporator drain hole is blocked up.
the heater should be fine.
i’m not familiar with your model number, but the evaporator cover should come off fairly easily and then you should be able to unblock the drain hole.
Thanks for the reply.
The evaporator cover has just two screws at the front by the door and has 2 rounded spigots on either side toward the back. When I undid the two screws at the front and let it drop slightly the evaporator coil dropped as well. It looked like it would swing down but I didn’t want to do it without knowing whether there was some sort of flex on the fridge pipes. I have worked in the past for several years on commercial A/C so I wasn’t looking to create a gas leak.
