Loud humming vibration

Check the hose that goes to the pcv valve, If it gets soft it will vibrate and hum.

Hey Joanne, I appreciate your inquiry!

Based off my understanding the freezer side of your Frigidaire refrigerator is making a loud humming noise. The humming sound could be coming from your compressor. If the sound is a new development it may be a possible issue with the fan pushing further against the wall. You may need to seek help from a professional technician for proper diagnosis and repair. This will help you from purchasing any unnecessary parts. Hope this information is helpful to you. -Matt

Check the fan underneath. If it has stopped, it hums quite loudly. It might just be jammed, but may need replacing. Is everything else ok, i.e.temperature etc.?

sounds like its bearings in a fan motor probably your evaporator fan motor it is located behind the plastic shell in your refrig. you have to take out the lining and then you will see the fan, evapartor and etc.

YOU PROBABLY NEED A MAIN TOTAL ASSY

A few more questions-
Does the sub hum without anything plugged into it except for power? If it makes a real loud hum almost a squeal then I think the rca cable between the receiver and the sub is dead shorted and needs to be replaced. If it's more of a low level hum, then it's a ground hum caused by many things, ie........the receiver and the sub being on different power circuits in the house.......sometimes diconnecting the cable tv feed as it enters the room while the sub is connected and humming to see if it stops........the easy fix sometimes is using a 3 to 2 prong ac adapter but lifting the ground on such a powerful amp could be a fire hazard.

if you have ice buildup then the fridge may be low on freon.
or there is dust clogging around the pump or fan is not running.
remove the bottom or back and look around the compressor.
see that the fan is running.

Got the same problem with my second TX-S3082WH Slimfit...the first had the same problem...it was deemed unrepairable and I was advised to return it to Circuit City...now a year and five months later Samsung support has been less than helpful as I am 5 months out of warranty...don't know what I'm going to do...any advice would be appreciated

The color wheel is the most common problem in DLPs that cause noise. To determine the cause: Turn the set off. If the noise goes away after about five seconds, then, the problem is the color wheel. If the noise goes away one to two minutes after shut off, then, the problem is a fan.
