When your AC unit fan stops spinning, you should clean the dust that has accumulated on the fan. There are a couple of reasons that an AC unit fan may stop spinning. I have prepared a list of possible reasons this might happen alongside the fixes.
Reasons Why AC Unit Fan Stops Spinning And Fixes
- There is faulty wiring. The wires that power the AC unit fan may have been compromised by rodents or just worn away. You should take your AC unit to your dealer to install new wires.
- The fan is loosely held. The fan may have loosened its grip over time. To fix this, take the appliance to a dealer to tighten the screws of the fan.
- Accumulation of dust. When dust accumulates over time it forms scum that makes it hard for AC unit fans to spin. You should clean your fan with soap and water to get rid of the scum.
- The mortar of the fan may be spoilt. The only solution, in this case, is to get a replacement for your AC unit fan.
