Sub-Zero 550 Fan Vibration

Our 15 year old Sub-Zero 550L has developed what sounds like a noisy fan. We have a loud vibration that comes from the upper portion of the unit. The noise stops as soon as the refrig door is opened and starts up when the door is closed. Noise greatly diminished after we vacuumed upper cooling fins, but returned the next day. Do we need a new fan, or just better cleaning? Does the whole unit need to come out to access the fan?
Thanks for any advice.

Re: Sub-Zero 550 Fan Vibration

You could try taking the fan assembly out and adjusting it or oiling it, sometimes it gets that back pressure when the door is closed because it has to work harder

Fan freezer too loud

It is more than likely that the fan motor itself is giong bad. It could also be that the blade is hitting the shorud or the blade is crackled and causing a bad vibration.

It is your evaporator fan. When the door opens power is cut to the fan motor.

Loud vibration

If it is a frost free check the fan inside. The fans can have bearing failure after a few years thus causing the vibration. Also the compressor underneath is mounted on rubber vibration dampers and if one of these rubber mounts fail then the compressor will start vibrating against the refrigerator frame causing a loud vibration. If none of these apply gently press on the side and front panel of the refrigerator to try and locate the source of the vibration as any where metal is vibrating against metal the side and front panel act as a sounding board amplifying the sound. If you cant locate the vibration then you may have a more serious problem and may need to call a technician.

Refrigerator Compressor has loud vibration

Clean the coils. what you are hearing is the valves as the pressure equqlizes. Also make sure that the fan by compressor is on while compressor is running.

Freezer evap fan vibration and noise

I suggest you unplug the frige and clean the blades of the fan of any dirt. If the fan is mounted with bolts through rubber gromets or washers take a caulk gun with 100% silicone and shoot silicone into these gromets or washers filling any voids between the bolts and rubber. Allow enough time to dry and see if this helps. please rate me

more likely a bad compressor, which is more sensitive to temperature extremes...may be cheaper to replace the frig.
