4 Possible Reasons Why The Fan To Your AC Might Have Malfunctioned

As the temperatures soar, air conditioning enables you to retreat indoors and enjoy the cool atmosphere away from the hot sun. However, it can be upsetting when you start your AC and find your fan not responding. Since the air conditioner utilizes a fan in the appliance's unit that is inside the house and also the one outside, a failure in either of them drastically decreases the unit's performance. Therefore, you should engage a technician to inspect your AC unit and repair the fan for peak functionality. Below are four possible issues behind a broken fan.

You Have a Problematic Condensing Capacitor

The part's role is to store the energy needed to start and operate your AC fan. However, your capacitors may fail if incorrect voltage or current passes through them. Overheating also burns up these components, rendering them ineffective. Accordingly, if you hear a humming noise, you should test the capacitors and replace them if they register no resistance.

You Have Tripped Breakers

Your unit operates on electric power, and issues could affect two locations. First, the main break box panel could have the tripped breaker due to overheating in the system or a short circuit. In addition, a power surge may blow a fuse, causing the breaker to trip and in turn disconnecting the current flowing to the unit outdoors. As such, it is advisable to reset the circuit breaker and replace the fuse and wiring for optimal power supply.

You Have Broken Condenser Blades

A grinding noise from the unit that is situated outside may indicate that the blade in the condenser is broken. As the fan belt wears out over time, it may loosen or tear, causing the fan to spin improperly. Furthermore, foreign objects such as sticks or plastic may lodge into the unit, impeding the fan's rotation and bending a blade. Therefore, you should contact a technician to replace the fan belt and clean the condenser unit for proper fan movements.

You Need to Reset the Thermostat

The thermostat allows you to adjust by displaying the current indoor temperatures. Therefore, an incorrect thermostat setting may give the wrong commands to the fan. For instance, if the AC is on but is set to heat, the part will not operate. Call an AC repair specialist to optimize your thermostat to cooling and auto mode. Additionally, they will guide you in selecting the right temperature to avoid discrepancies between the room temperature settings.

If your fan is defective, you inevitably incur higher energy expenses and possible damage to other components. Therefore, you should engage an AC repair specialist to routinely tune up your system for the fan's optimal functionality.
