Hello Barb;

My name is Peter. I am a retired field service refrigeration technician.

Inside your compressor are two flat plate valves. Unfortunately, these plates are broken. This causes your compressor to knock loudly. You can confirm this. Pull your refrigerator out. Without unplugging, remove the bottom cover. Observe the compressor. You will see the compressor jerk and jump.

It is expensive to replace a compressor. Depending on your model it can cost between $450.00 & $650.00. The rule of thumb is: "If the cost of repair is 1/3 of the original value purchase a new unit".

Sorry for the bad news.

Peter, Baltimore, Maryland

SOURCE: "knocking" from the freezer GE Profile PFS22SBSBSS fridge

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.

SOURCE: refrigerator knocking noise

the motor could be on the way out. Put your hand (carefully) on the motor (back of the refridgerator), if it is too hot to touch then the motor is burning out and will need to be replaced.

SOURCE: Knocking noise when compressor chuts off

this is a problem that has been going on for close to 35 years. back in the day some genius decided to redisgn the compressers made by tecumsah. they made a rotary compressor in other words the compressor inside the housing turns 360 degrees rather than being pumped from a piston that went up and down.this rotary compresser spun around very fast and when it shut off the three springs that held the compresser would sort of bend a little. as time went on this weakening of the springs would cause the compresser to hit the housing, thus creating a knock or ping or whatever else you want to call it. so customers would call up factory service ans say their refrigerator was making noise. so a service tech like me would go out hear the sound and order a new compresser. after a while the replacement compressor may or may not make noise. after a few years tecumsah said that they would no longer credit the service companies for noisy compressor problems and that the noise was the nature of the beast. so depending on variables such as who you talk to when you request service and the tech who shows up at your house you will either get a new compresser or not. i hope that explains your problem to you it's hard to write all this down rather than standing in your kitchen and telling you in 45 seconds good luck. you can take this all the way to the president of whirlpool if you get no satisfaction

SOURCE: knocking noise coming from Whirlpool Gold refrigerator

I also have a new Whirlpool Gold fridge (bottom freezer with French doors) and it was making a knocking sound. The knocking sound would start when the fridge kicks in and starts running to cool, and would last for about a minute or less and be a slow knock.
I called Whirpool customer service since it is new and on warranty. They sent out a technician and he said the knocking is from gas/air built up in the copper tubing for the freezer because the copper tubing is too cold, and when the fridge first turns on it forces the air through, making the knocking sound.
His "fix" was to adjust the copper tubing so that it is closer to the heat of the motor/compressor and heat of another copper line so that the cooler line stays warm so the air/gas doesn't build up. His fix worked slightly, but the fridge is still knocking, just not as bad and not as long - it knocks fast for about 5 to 10 seconds instead of a minute.
Going to call customer service again soon and see where to go from here.

SOURCE: GE Profile making knocking noises at different times

I have the GE profile Refrigerator with ice maker in the refrigerator compartment. Mine was knocking loudly for long periods of time, so I finally removed the icemaker by removing the side panel in the icemaker compartment held with 1 phillips head screw, disconnecting the electrical plug (unclip), pulling the tab of the icemaker down (on top) and sliding it toward the door, thus removing it. There was ice frozen in the motor compartment that was the problem. I let it thaw out and re-installed. All was OK after that..

Our new KitchenAid side by side refrigerator makes a knocking noise after you close either freezer or refrigerator door. We haven't fully installed the ice maker yet, so I know it's not...


The knocking noises heard from the Freon moving through the sealed system are perfectly normal and usually do not last long. Since the evaporator coil is mounted in the freezer section, the noise is usually louder there. Some people say it sounds like marbles knocking together.

check the compressor for operation adn check the fan in the back of unit to make sure it is running...whirlpool units are notorious for compressor relay failure normally they click in and out every few minutes... if it is a knocking noise and continuous make sure compressor is not trying to start and sitting there shaking... normally it will stop after a few minutes and then start again....

I have a 2003 Sequoia it makes a knocking sound when I first crank it up. It goes away after about a minute . What could this be.


Probably more of a tapping/ticking sound, ours does it too. The mechanic said it is fairly common on Toyota's and it is the lifters. The fill up with oil after a little bit and stop ticking. Knocking sound is a lot louder and usually comes from a spun rod bearing or something a lot worse. Have it checked out anyway I say.

Amana refridgerator mdl abl2222fes knock noise


sounds like the compressor vibration dampers are wearing out. the dampers are the rubber washers that seperate the compressor from the chassis of the fridge. when they start to deteriorate, and the compressor kicks on, it will bounce against something in the chassis, causing a knocking noise.

Knocking noise coming from Whirlpool Gold refrigerator


Mine does it too. I know what it is because I repair them for a living. That is the sound of ice expanding as the defrost heater comes on to melt the frost on the evaporator. The next ime you hear it make a note of the time. Every 8 to 10 hours it will go into defrost mode. The ice box will also quit working for 21 minutes.
