Summer heat and high temperatures can be extreme in Phoenix. You need a good air conditioner for comfort and relaxation indoors when it is too hot to be outside. Unfortunately, air conditioners can break down unpredictably, creating significant discomfort in your home.
Having a malfunctioning AC is stressful, as it causes moisture to build up in your home. Some of the reasons that can cause your air conditioner to malfunction include:
An AC Condenser Fan May Be Not Spinning
An outdoor air conditioner has two fans: one inside and the other outside the AC unit. The outside AC unit may not function effectively if one of the fans is compromised. You can identify if the blades in your AC unit are spinning by listening for a humming sound. Your AC condenser fan may not turn due to power issues, a burnt-out motor, a worn-out capacitor, or a faulty compressor contactor.
An AC Compressor Might Be Working, but The AC Fan Is Not Spinning
When an air conditioner compressor works but the air conditioner fan is not spinning means the motor and capacitor or one of them has malfunctioned. When a capacitor is not functioning correctly, it will not provide electricity to the fan motor. An incorrectly functioning capacitor causes the AC fan not to spin. The outdoor AC unit motor will not turn the blades, hindering the air movement in the house.
Letting the AC system run in that state can cause overheating, destroying the compressor. Ensure the AC system is turned off until an AC technician checks it.
The AC Compressor and AC Fan May Not Be Working
The compressor’s lack of a humming sound and the fan not turning implies that power is not getting to the AC unit. In such an instance, check the circuit breaker for tripping. Use the thermostat to turn off the AC and reset the circuit breaker if it has tripped. Next, turn on the AC unit at the thermostat to check if the problem is fixed. If this tip fails, then the problem might be the compressor contactor.
Why My Air Conditioner’s Fan Might Stop Running
There are many possible causes why your air conditioner’s fan might stop running. The most common reasons include:
- Issues with the capacitor
- Faulty belt
- Blocked air filter
- Power issues
- Burnt out motor
A capacitor is a small cylindrical device that provides energy to the AC unit’s motor. Air conditioning systems have several capacitors responsible for starting up the AC unit and providing power to keep the unit running. You know your capacitor is dead or bad if your outside air conditioner: has trouble turning on, shuts down on its own, and does not blow cold air. In addition, capacitors can wear out over time and need to be replaced.
- Broken motor
Fan motors tend to break down if you overload them or fail to give them proper maintenance. A broken motor makes the air conditioner’s fan stop running and should be replaced immediately since it affects the whole AC system’s performance.
- Blocked air filter
A blocked or clogged air filter restricts airflow in the air conditioner’s system leading to ice build-up around the evaporator coil. This ice build-up on the coil causes the fan not to work.
- Issues with the contactor
A contactor with issues inhibits your system’s electrical flow, making the AC components malfunction due to lack of electricity. In addition, contactors develop issues because of system overheating and normal wear and tear. Therefore, always ensure proper maintenance of your contactor to ensure your air conditioner has a healthy working condition.
