Tempstar a/c condenser screeching noise

When the outdoor Tempstar a/c condenser unit turns on it makes a loud screeching noise for a few seconds, then quiets down. Sounds like the fan is hitting something right at the beginning or maybe there is something shorting or a part that needs changing. Any advise?

Could be the fan motor's bearings. Try turning the fan by hand to see if spins freely or is tight. If it's tight you can try oiling it but that may not work for long.

Tempstar Air Conditioner wont come on


Sounds like you need a new contactor in the condenser. The low voltage is grounded. Remove the low voltage (likely 2 wires) at the condenser and wire nut the wires leading inside. With an insulated screwdriver manually push in the contactor and be sure both compressor and fan run. Then replace fuse and turn power on to air handler with a call for cooling. Obviously the outdoor unit won't run because you unhooked the low voltage but if fuse doesn't trip then it's likely the contactor. Good Luck

Fridge making loud screeching sounds


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!

Mine is a FDB635RFS4 model - issue is loud screeching noise


i recently had the same problem of a loud screeching noise. my unit was installed new in 1999 and has worked well up to this point.

when i disassembled the tub water filter i found the filter was heavily clogged (it is supposed to be self cleaning), and i also found glass shards from a broken wine glass. i further disassembled the plastic housing under the filter ( held in place by three torx drive screws ) which covers the pump impeller and holds the lower spray arm. while i did not find any blockage in the pump area, and no abnormal sound when i turned the impeller by hand, i did find that one of the pump impeller vanes has a small chip which probably makes the impeller unbalanced resulting in more than normal vibration. i cleaned the water filter and reassembled the parts and the original screeching noise is now gone.
