Aircon Fan Working but Compressor Not Running

Aircon General service

When your air conditioner fan is working, but the compressor is not running, it can be frustrating—especially during hot weather. This is one of the most common air conditioning problems faced by homeowners and businesses alike. While the fan circulates air, the compressor is responsible for cooling it. Without a functioning compressor, your air conditioner will blow warm or room-temperature air instead of refreshing cool air.

In this article, AIRCOOL AIRCON explains the common reasons behind this issue, possible solutions, and when you should call a professional technician.

The compressor is often referred to as the "heart" of the air conditioning system. It compresses refrigerant and circulates it through the system, enabling heat to be removed from indoor air. When the compressor fails to start or stops running, the cooling cycle is interrupted—even if the fan continues to operate normally.

This is why an aircon fan working but compressor not running problem should never be ignored.

Common Reasons Why the Aircon Fan Works but the Compressor Doesn’t1. Faulty Capacitor

A defective or weak capacitor is one of the most frequent causes of compressor failure. The capacitor provides the initial electrical boost needed to start the compressor. If it fails, the fan may still run, but the compressor won’t start. aircon gas topup

2. Tripped Circuit Breaker or Electrical Issue

Sometimes, electrical problems such as a tripped breaker, blown fuse, or loose wiring can prevent the compressor from receiving power. The fan and compressor often run on separate circuits, which explains why one may work while the other does not.

3. Overheating Compressor

If the compressor overheats due to dirty coils, restricted airflow, or prolonged usage, it may automatically shut down as a safety measure. In this case, the fan may continue running while the compressor remains off. aircon repair

4. Low or Leaking Refrigerant

Low refrigerant levels can cause pressure imbalances, leading the compressor to shut down. Refrigerant leaks not only reduce cooling efficiency but can also damage the compressor over time.

5. Faulty Thermostat

A malfunctioning thermostat may send incorrect signals to the air conditioner. This can result in the fan running continuously while the compressor fails to engage.

6. Compressor Failure

In older air conditioning units, the compressor itself may be worn out or damaged. This is a more serious issue and often requires professional repair or replacement.

Can You Fix This Problem Yourself?

While basic checks—such as resetting the circuit breaker or cleaning air filters—can be done at home, compressor-related issues should always be handled by trained professionals. Air conditioners involve high voltage and pressurised refrigerants, which can be dangerous if handled incorrectly. Midea e1 error

Attempting DIY repairs may lead to further damage and higher repair costs.
