Air Conditioner Fan Not Spinning

The ac s capacitors are small cylinder components that send energy signals to power the fan motor and the rest of the ac unit.

Air conditioner fan not spinning.

If it starts spinning then the issue is the capacitor. Take a stick or screwdriver and spin the fan blade. Most of the air conditioning systems that use belts are outdated units. Most fan motors work overtime especially during the summer months.

One of the simplest explanations for an ac fan not spinning is a dead fan motor. Don t put your fingers in or near the grate if the fan takes off and then keeps going on its own you more than likely have a bad start capacitor. Slide a long thin wooden stick through the fan grate and gently push one of the blades to try to get the fan spinning. It is not unusual for the bearing that the fan blade unit turns on to become so clogged with debris that it cannot turn.

This part has two blades. The fan in your air conditioner s condenser unit the big box outside blows air across the condenser s coils enabling it to turn warm refrigerant gas into a cool liquid which it then uses to create cool air for your home. Gently push on one of the fan blades. If the motor is still spinning albeit slowly it is not moving enough air for your hvac unit to function normally.

On one side the fan blade works by drawing in outside air over the condensing coil. With the power off to your condensing unit here is a simple test you can do. To test it use a screwdriver or branch to poke through the condenser unit s vents. If you have a bad capacitor it may take a while for the fan blades to start spinning once you turn on the unit.

This heavy use results in a significant amount of wear and tear and eventually the motor will give out. Dual shaft fan motor check the dual shaft fan motor or the circulation fan motor for any problems or defects. One of the most common reasons fans stop spinning is because of a dead capacitor. If you can see dirt and debris in the small gap where the fan blade unit connects to the bearing and motor clean it using your fingers and the side edge.

Fan blades gather a tremendous amount of dust and debris that then settles behind them away from the force of the air. If the fan on your ac unit has stopped working the system will be unable to cool your home until it is fixed. This process is done so the unit can successfully dissipate the heat. Don t risk damaging your compressor.
