Frigidaire Gallery FGHC2331PFAAb CONSTANT annoying shrill sound

Hi @willa78

It could also be the evaporator fan (supplier link only to show where it is located)

With most refrigerators, the evap fan runs when the compressor is running and it will stop when the door is opened (either door) and start again when the door is closed. It will also stop when the compressor stops.

The condenser fan can run at any time whether the doors are open or not or even if the compressor has just stopped, as is it temperature controlled

If the noise stops when a door is opened or when the compressor is stopped due to set temp reached or if a defrost cycle is occurring then the evap fan may be the cause.

If it is the fan search online for 241509402 to find suppliers that suit you best.

If the fan is covered in ice when you check it, then there's a defrost problem.

Access to the fan is through the door at the front of the refrigerator. You have to remove a panel on the inside wall at the back of the compartment.

Be safety aware and disconnect the power when inspecting the fan
