Frigidare White Westinghouse Refrigerator

Try looking for any pipes that are rattling against the cabinet , if not, I'm afraid compressor problem.

Could just be a worn belt or faulty or loose tensioner. Does it only make noise when AC compressor kicks in? If it's not a metallic sound, and sound more like a screech/squeel, then I'd look close at belt condition, and tension.

Keep a close eye on your temp in the refrigerator and freezer. this noise sounds like your start device on your compressor and if it is, your refrigerator is has already stoped working.

It could also be the ice maker water inlet valve, calling for water, (( there could be a couple of reasons this can happen.

I would first sugest to turn off the ice maker and pull the machine out so you can get to the rear bottom of the machine and listen for the buzz noise. if it is still making the noise and is by the compressor ((( the big black thing ))) then you have a 50 - 50 chance that you will only need a start device. It is worth the shot. But it could also be a bad compressor.

The screeching noise is probably the belt slipping under load.
I would start by replacing the belt, and if it happens again, then it is probably a tight bearing or similar on the pump, that is causing the problem.

Generally, in my experience, the loud screeching is caused by one of the fan motors or fan blades. There is a fan inside the cabinet (possiblle two, one on the freezer and one on the refrigerator side). Also, there is a fan underneath the unit near the compressor (probably in the back).

If the screeching is coming from underneath then pull the unit out from the wall and remove the cardboard cover at the bottom back. Now turn the unit on and check for where the screeching is coming from.

If it is the fan blade (hitting something) or the motor, you can remove these and replace them easily. UNPLUG THE REFRIGERATOR BEFORE TOUCHING ANYTHING UNDERNEATH THE BACK OF THE REFRIGERATOR.)

Good Luck!

If this sound is when the compressor is cutting on or off it's the internal parts of the compressor. It can work like this till it brakes. There is no way to fix it without replacing the compressor. If you can put up with the noise just wait. Or it could be the fan behind the back cover inside the freezer hitting somthing like ice build up. Try to pinpoint the area the noise comes from.

compressor start device going bad.

It sounds like the fan motor needs lubricating. Do you need help with this?

The compressor is that black casing you see at the bottom of your refrigerator - inside this sealed case is the motor assembly which stits on 3 or 4 springs that act like a cushion - you have a little gap at the bottom where the lubricating oil is present. Your springs have likely worn out and when the compressor shuts off the assembly is banging against the rigid casing make that loud "klonk" or bang noise. It IS normal for compressor to make some faint "tick-tick-tick...tick.....tick" when shutting off, but loud banging, bell sounds, etc, means the assembly is banging on the case from the inside - you can indeed live with the noise, your compressor will function normally, probably for months, or even years - it can also keep wearing out and one day the noise might get very loud (like a very high humming noise) - There is NOTHING that can be fixed, you either pay $400+ to change the compressor or buy a new refrigerator - If you DO replace a compressor usually the replacement will be noisier - Keep a thermostat inside your refrigerator at all time to make sure your compressor is still keeping your refrigerator and freezer cool.

check bearings or shock absorber.
