Can You Tell When The Fan Motor To Your Air Conditioner Is Damaged? 4 Sure Causes

by Jamie Shaw

When the air conditioner fan is damaged, you will not feel cold air blowing out of the unit. Fan motors can fail for many reasons, like loss of lubricant, a failed run capacitor, or a damaged bearing in the fan belt. Fan motor failure is a complex problem because it might go unnoticed for a long time. The failure also puts a lot of stress on the compressor and shortens its lifespan. It is advisable to always be on the lookout for signs of fan motor and capacitor damage so that you can get an AC technician to fix it. Here are four causes of the problem.

1. Breakers in the Off Position

Tripped circuit breakers are a leading cause of fan motor and capacitor failure. When the circuit breaker fails, your entire unit will have no access to electricity. Check the electrical panel for the breaker for the air conditioner. If the breaker is in the off position, turn it to the neutral position before turning it back on. After resetting it, check and see whether the AC fan motor resumes its regular function.

2. Filters that Have Accumulated Dirt

You should also check the condition of the air filters and ensure they are clean. Dirty filters block airflow through the system, causing a chain reaction that often leads to fan motor failure. If the filters are dirty, clean or replace them and check whether the motor resumes its function.

3. Obstructions on the Blades of the Fan

Sometimes, the fan blades stop turning because they have obstructions. You can check for the obstructions after you have turned off their air conditioner. Go to the outdoor unit and try to turn the fan blades with a tool like a screwdriver. If there is an obstruction, you will feel some resistance to the free movement of the fan blades, and you will need to remove the obstruction.

4. Damaged Capacitor

The fan blade motor and capacitor always work together. Check to see whether the capacitor is damaged, and if it is, then get a new one. You can also use a tester to see whether yours is still functional. If you cannot handle the replacement process, call an AC technician to do it for you.

Dealing with fan motor problems on your air conditioner unit is a complex process that needs expert help. Call a professional once you suspect any issues with your system for residential AC repair.
