Everytime the compressor stops there is a loud 'bang' sound.

The "loud bang" is symptomatic of your compressor trying to destroy itself.

if you have an ac running during the day but it could be ice on the evaporator unit melting off and falling into the drip tray as the unit reaches the controlled air temp setting and switches off

Your fridge's compressor motor is suspended inside the compressor housing on three or four springs. These springs are designed to hold the motor load in a vertical position. Transporting a fridge on it's side can stretch or break these springs which can cause a shudder stop condition (the fridge makes a shuddering banging noise everytime the compressor stops and sometimes when it starts).

It's a good idea to let a fridge sit for a bit anytime it is moved. Over night won't hurt but an 8-10 hours is more than enough time some say less.


the internet consensus seems to be that you should limit the amount of time the unit is not upright. And as stated above, leave it upright at least overnight before starting it. Apparently damage can arise from mixing of lubricant and coolant, so damage is more likely in an older unit with worn seals.

sounds like blown relay in compressor?

sounds to me like you have a misfire?

The actual internal motor in the compressor dome is mounted on springs. Over time these get weak and hence the loud bang noise when the motor hits the sidewall of the compressor housing. It is not too serious and will probably work for ages. Just anoying. Leave it until it really packs up.

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.

if it’s a banging sound--- I know one of the noises the system 2000 will make is a bang or rattle at the end of the run cycle, which we call "shudder stop". If this is your noise then I have to give you some bad news here. Sorry....... The only way of repairing this is by having your compressor replaced as it has to do with an internal problem in the compressor itself. There may be a silver lining, though, if you are the original purchaser and you have the receipt. Some of these systems came with a 10 year warranty on the compressor, so you might want to check this out.good luck

if its a loud banging noise when the unit kicks off then broken spring in compressor will have to replace compressor check your 2-5th year warrenty in your owners manuel

some popping noise is normal but if it is banging when it stops it needs a new compressor.what has happened is one or more motor mount is broken or weak it could run like this for months or years but it is annoying! if its warranty they have to replace it.
