Freezer humming, freezer burn and melting items in less than a day?

Hi @sunandstars ,

Check whether the evaporator fan located inside the freezer compartment behind a panel is operating or whether it is iced over.

Here’s a link to the freezer parts diagram for your model, which shows the layout which may help.

Here’s a link to the fan part which has a video showing how to access the fan in the freezer. It may not be the exact same way for your model as it may just show the one way to remove it.

If the fan is iced over then you have a defrost problem.

This could be caused by a faulty defrost heater, a faulty defrost thermostat or a blocked drain leading from beneath the evaporator unit to the evaporator pan under the compartments near the compressor.

If the drain in blocked, the meltwater from the auto defrost cycle can’t drain away and evaporate and will refreeze when the defrost cycle has ended and this continues with every defrost cycle which occurs ~ 10 hours, so the ice will build up and eventually it will ice over the fan forcing it to stop, even though it may still try to turn, hence the humming sound perhaps.

Do the lights in the refrigerator compartment turn off when you manually operate the door switch, with the door open? If not then it may be a faulty door switch. Besides controlling the lights, the door switch also signals the control board to turn off the fan as you don’t want to blow cold air out of the refrigerator with a door open.
