When there is a noise it is important to know the source of the noise. In the case of a fridge the fault is usually a poor compressor motor assmebly mounting. Over a time the bushes and the mountings can wear out and result in noise when the compressor vibrates. Also when the motor runs , in many cases it can produce a sympathetic vibration as the grills, the rear fitting or plastic can make noise. finally a fault within the compressor can be related to this specially if you can place a hearing probe to know the emission of noise.

My KitchenAid refrigerator works perfectly, but makes a loud knocking sound. Sounds like bottles rattling or being pumped. Hard to describe.

Knocking and rattling can be milk bottles chinking together inside although there days milk is no longer in bottles. Or it can be a problem with the compressor, low on refrigerant gas or oil.

Depending on age or type, it is ether fix or replace.

Condenser fan is knocking

Sounds like you need to clean off the fan blades. Over time the fan will build up so much dust it can interfere with the fan cooling the condensing coils. If the fan can't keep the coils properly cooled off the temperature in the refrigerator will rise. Make sure to unplug the refrigerator before cleaning the fan. Of course it could be that your condensing fan motor is just going bad (bearing etc.) If you are not comfortable checking the unit yourself contact an appliance service company.

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.

We purchased a new KitchenAid Side by Side Refrigerator Model # KSRG25FVBL01 that makes a loud knocking noise accompanied by rattling from the date we purchsed. We are getting runaround in getting it fixed...

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.
Refrigerant (Freon) moving through the system can cause a vibration/rattling, especially as the compressor first starts up.
  1. Vibrating from top of cabinet Remove, rearrange or pad any stored items atop the refrigerator such as houseplants, coins, pens, etc.
  2. Vibrating from back or sides of refrigerator Move refrigerator away from water line in the rear or away from walls / cabinets along the side of the cabinet. Refrigerators with a static condenser on the back require a rear clearance of 3 inches across the top of the condenser.
  3. Vibrating from the bottom of refrigerator Level refrigerator so all 4 rollers / feet rest solidly on the floor.
    Hope this works.....

Kitchenaid refrigerator / freezer knocking noise

Hmmm. Makes sure it is not the fan inside the freezer. The compressor is not capable of loud noise since it is sealed and sits on rubber mount. The knocking might be due to the fan blade hitting ice build up. You should not see any frost in a freezer. If there is frost, you can defrost completely then set the fridge to a lower setting.

We have a kitchenaid ktrc 22e and it has just started thumping intermittently. I think it sounds like the copper pipe for the ice maker on the back of the refrigerator, but haven't got it totally narrowed...

I found out it's not the refrigerator, but a woodpecker knocking on the dish on the roof right above the refrigerator. Go figure, not a refrigerator problem... ;)

Loud Knocking/Ticking Sound During Cycle

have you lowered the top basket into the lower position? if so the spray arm will knock the cutlery /plates. it sounds as though it is a spray arm problem. remove them and put it in wash to see if the noise goes. if not there may be an obstruction in the wash pump, this is a stripdown job then.
