Why would condenser fan motor keep burning out everytime it?
It most commonly occurs when the blower fan motor becomes aged or is overworked. A lack of regular maintenance is generally to blame for blower fan burnout.
Why is my new condenser fan motor overheating?
Not having the fan blades installed in a correct position can result in a lack of airflow and cause the motor to overheat. Lack of maintenance. If the motor has not been lubricated, or the unit kept clean, this can lead to overheating problems.
How long do AC condenser fan motors last?
The average lifespan of an AC fan motor is about 12 years. An AC fan motor can last more than 12 years if it’s kept clean and cooled as needed. On the other hand, without annual maintenance checkups, your fan motor may only survive between one and three years.
What causes an AC blower motor to go out?
Like other components in your HVAC system, the blower motor can wear down over time. Some of the reasons a blower motor might fail are overheating, and excessive moisture. When dust, dirt, and debris build up, it can cause the windings and bearings to burn up more quickly.
How do I know if my capacitor or fan motor is bad?
One way to know for sure is to turn off the power to the unit and unscrew the side panel to inspect the capacitor . The capacitor looks like a large, cylindrical battery, with cables connected to it. Its top should be flat. If it looks swollen, the issue is with the capacitor.
What happens when the condenser fan motor fails?
However, a condenser (outdoor) fan-motor failure can be even worse. Since the refrigerant isn’t being condensed, it causes the pressure on the discharge side to get very high and the compressor (since it isn’t being cooled) gets extremely hot, which breaks down the internal lubricant and contaminates the system.
What causes condenser to overheat?
Three of the most common reasons why HVAC systems overheat are clogged air filters, refrigerant leaks, and dirty condenser coils. These issues force your heater or air conditioner to work harder to produce the temperature and quality of airflow you need, which results in the system overheating.
How do you test a condenser fan motor?
Quote from the video:
Quote from Youtube video: Set your tester to continuity. Test for continuity across the two terminals. If there is continuity the board is good. Remember. This will only be true if the thermostat is calling for cooling.

Can a bad capacitor ruin a fan motor?
(This is called a “start/run capacitor” and they’re used in many A/C systems.) In either case, a bad capacitor will strain the fan motor and may cause it to burn out completely.
What are the signs of a bad capacitor?

Will condenser fan run if compressor is bad?
Why Is the AC Compressor Not Working Although the Condenser Fan Is Running. The compressor is a significant component of an air conditioner system. It keeps the refrigerant flowing through the system so that the AC can function correctly. Any problem with a compressor will cause the air conditioner to stop working.
Can I run my AC without a condenser fan?
It’s the part of the unit that pumps air through the system. Without that circulation of air, your AC won’t cool your home. Because the fan motor is one of the hardest working parts on an air conditioner, it is subjected to a lot of wear and tear that can lead to frequent repairs or replacement.
Why is my AC condenser fan not working?
If the compressor is working, but the fan won’t turn, then the problem is most likely with the motor and/or capacitor. If you don’t hear any sounds to indicate that the compressor is working, and the fan isn’t spinning, the most common causes are a lack of power or a faulty compressor contactor.
