"knocking" from the freezer GE Profile PFS22SBSBSS fridge
Our refrigerator had started making "knocking" sounds around October/November. It mostly happened in the evening around the same time so we thought perhaps it was a cyclical thing. Lately it's been occurring more frequently and much louder than before. The sound usually lasts for less than a minute. It literally sounds like someone is banging on a pipe inside the freezer section. Any thoughts? We've had this fridge since May 2007 so it's not very old. We've had repair men come to look at it but we're not really satisfied with their answers.

The compressor could be a little lose from shipment from factory, to warehouse, to your home. If the bushings are lose, when the compressor kicks on, it can cause a jarring or vibration in the system lines. Disconnect the power from the wall before you attempt to touch the compressor and see if there is any play in the mounting bushings for the compressor.

It really depends where the sound is coming from. You will get a knocking sound when the fridge makes ice, and a knocking should when the compresser starts land stops, or your fan in the freezer may be hitting some ice build up in theevaperator
If it seems to be coming from underneath the unit it could be the compressor.

That's usually mounts inside thecompressor. Usually when the compressor cuts off. It could still last awhile so if you can put up with thenoisejust wait for it to quit
before replacing thecompressoror getting a new
fridge. Any other noise would be from a fan. One in the freezer behind the back panel and one under the unit where the compressor is.
clean the coil behind the fridge or under the fridge (where ever they are) and make sure both fans are running, the one in the freezer and the one underneath freezer needs to be 0 degree F to start ice maker
Open the freezer door and see if the sound is there or if its near the floor. This needs to be corrected soon to prevent damage to your refrigerator. Your explanation makes be think the fan inside the freezer is loose or has ice buildup around the blades or the fan blade has become unbalanced in some way...Let me know and please rate me, Thanks, Sea Breeze
Unplug and closely examine the area for a loose fan blade or anything that may be causing the noise. Better now than to get damage that could be prevented. Let me know what you find, Thanks, Sea Breeze
Hi. Its either a bad motherboard or control board. I would check the control board for any obvious signs of damage to the board first. I've seen the control board go blank on the GE side by side and it turned out to be the motherboard. The motherboard is located behind a cover on the back of your refrigerator cabinet. You should have a new motherboard on hand at all times because they fail alot. Be sure to put a surge protector on your refrigerator. Good Luck, Mack
