Air conditioner evaporator fan not running is a common and problematic issue. Failure to address it can lead to freezing of the evaporator coils, shortening the lifespan of the unit. Read on to understand the causes and solutions for this issue.
1. Causes of Air Conditioner Evaporator Fan Not Running
Loose or severed power supply wires to the evaporator fan
After some time of usage, the power wires connecting the fan blades to the motor can become severed or loose due to rodent damage. This condition prevents the evaporator fan from functioning and poses a hazard to users.
Malfunctioning evaporator fan
Other factors causing the air conditioner evaporator fan not to rotate include loose, worn, dust-clogged, or dry bearing blades. This issue renders the fan unable to operate consistently, resulting in intermittent function.
Capacitor Malfunction
This is one of the reasons why the air conditioner evaporator fan may not run. Capacitor issues significantly affect the fan blade rotation speed. Therefore, if the power supply to the air conditioner is erratic or unstable, it will cause the capacitor to continually switch on and off. Prolonged occurrences of this condition will damage the refrigerator, leading to harm to the evaporator fan and shortening its lifespan.
Malfunctioning Circuit Board
After prolonged use, the electrical circuit board will be affected by oxidation, improper electrical usage, or exposure to moisture causing water leakage into the circuit board. Over time, this degradation will lead to the circuit board deteriorating, resulting in the air conditioner evaporator fan not functioning.
2. Guide to Fixing Air Conditioner Evaporator Fan Not Running
Repair or replace power cord as needed.
Check the quality of the power cord using a multimeter. Carefully inspect for any breaks. If damage is found, assess whether to repair the connection or replace the electrical cord. If lacking expertise or tools, seek assistance from repair services promptly.
Replace the fan blades for the air conditioner.
Fan blades significantly impact the operation of the evaporator fan system. Therefore, if this component encounters an issue, promptly replace the fan blades to ensure the air conditioner functions properly. However, due to the complexity and safety considerations of this replacement process, seek assistance from technical personnel.
Repair or replace circuit board as needed.
A malfunctioning evaporator circuit board can affect the operation of the air conditioner fan. If encountering this situation, contact skilled repair technicians to rectify or replace the circuit board.
Replace the faulty capacitor
If the evaporator fan operates inconsistently due to capacitor issues, replace the capacitor with a new one. This is the most effective solution. Seek assistance from specialized technicians for safe and efficient replacement procedures.
