Symptoms
- No fan noise near the back or bottom of the unit when running
- Unit feels hotter than usual on the outside
- Cooling performance has dropped
- Compressor may shut off on overheat protection
Likely causes
- CommonDust or debris jamming the fan bladeBuilt-up lint and dust can physically stop the blade from turning freely.
- CommonWorn fan motor bearingMotors wear out over years of continuous use and eventually stop turning.
- PossibleFan wiring connector loose or damagedA disconnected or corroded connector cuts power to the fan even if the motor is fine.
- Less commonFaulty relay or control board controlling fan powerSome designs route fan power through a control board component that can fail.
What to do
- Unplug the unit and locate the condenser fan, usually near the compressor at the back or bottom.
- Clean out dust and debris around the fan blade and housing with a vacuum or soft brush.
- Spin the blade by hand to see if it moves freely or feels stuck.
- Check the wiring connector to the fan for looseness or corrosion.
- If the blade spins freely and wiring looks fine but it still won't run when plugged in, the motor likely needs replacement.
- Address this promptly, since a non-running condenser fan can shorten compressor life.
Tools and parts
