Refrigerator is making a rattling chattering noise; what is the problem?

Sounds like a release bearing is going bad.

We have a different model Samsung, and I've heard a vibrating or buzzing noise twice. First, if the water filter isn't an exact fit (even Samsung's filters rattle), it will rattle. Second, if either of the ice makers gets stuck or jammed, it can make a vibrating noise. If our freezer drawer isn't making a good seal, ice will build up under the drawer or in the slides. Ours makes more of a humming noise, when this happens. Other areas to check: something stuck in the runner of your drawers or shelves (if yours pull out). There are also vents that draw air in and out of the cooling unit, and things in front of them may vibrate or rattle, too.

check the suspension and steering linkage, control arms, shocks struts and bushings

The timing chain area also takes in the alternator and water pump. To isolate the source of the noise, use the old mechanics trick.

Place a 3 foot 1/4 inch brass rod against the flap at the opening of your ear and push until it closes. Place the other end of the rod against various engine components and listen. The noisy problem will conduct the noise up the rod to your ear and you can hear quite precisely where the problem is. Much safer than laying your ear all over a running engine.

You can also loosen the fan belt and run the engine without alternator or water pump (briefly) to see how that affects the problem. Chatter on start makes me think of starter and Bendix gear problems. Sounds like a 2 person diagnostic team to me; one to start the car and one to listen and probe.

Don't know if Subaru Forrester has an engine that has valve interference at piston Top Dead Center. If it is and the timing chain breaks, you are looking at major $$ to recover.

Usually it's wear in the clutch basket allowing your clutch plates to rock back and forth causing a rattling or chattering noise from lower end.

If you have an icemaker, that would be the sound of either the mechanism emptying the cubes or the water valve shutting off. If the water valve is going bad, or the switch that shuts off the water valve is going bad, the water valve may 'chatter'. If this is the case, try shutting off the icemaker, or even the water supply to the unit to see if it stops.

If you don't have an icemaker, then the circulation fan may be rattling a bit or has something in it, like a bit of paper. Circulation fans are typically behind a panel in the freezer sectionon most models.

Some units rattle the metal cooling pipes a bit when the compressor motor starts up. This is a more metallic clanging sound.

If it's a very sharp repeated clicking noise, that may be the sound of the motor-start capacitor going bad.

Hi, Could you get me a model # so I can see exactly what machine you have please?
Does the rattling noise sound like a fast chatter with metal or is it a dull plastic sound?

Thanks
Vic

• This is a very first sign of the dying compressor, but nobody knows how much longer it's going to last. It can be "days" and it can be "months".
• First check that it is the evaporator fan (in the freezer) and not the condenser fan (by the compressor) that is making the noise.

Other tips:

• Hissing and popping is normal on frost free refrigerators, it is the defrost heater
• Check that the refrigerator is level
• Check the drain pan
• Check the condensor fan
• Check the evaporator fan
• Inspect the compressor mounts
