Why is my AC compressor turning on and off rapidly?

Your air conditioner may be short cycling because it is repeatedly starting up then overheating (and shutting down) due to a bad compressor, dirty filters, dirty coils, low refrigerant, or frozen coils. A malfunctioning compressor will overheat. Dirty filters will prevent adequate airflow and cause motors to overheat.

Why does my AC compressor keep going bad?

1. Dirty coils. When dust, grime and mineral scales build up on the condenser coil, the air conditioner can’t expel enough heat from the system and it’s forced to run constantly trying to cool your space. The increased pressure and temperature can cause the compressor to overheat and fail.

How does the AC compressor work in a Toyota?

Toyota uses the AC flow control sensor to detect the amount of refrigerant flow through the compressor. Based on the reading, the ECM can adjust idle speeds and engine load parameters to save gas. The AC flow sensor converts flow rate to a voltage that’s sent to the AC amplifier which communicates digitally with the ECM.

Why is the AC clutch on my Toyota not working?

If the AC compressor clutch won’t engage on your late model Toyota and you find a B1479 Flow Control Circuit trouble code stored, the problem is usually a bad flow control sensor. Toyota uses the AC flow control sensor to detect the amount of refrigerant flow through the compressor.

What does serpentine belt on AC compressor do?

The serpentine belt or drive belt runs the AC compressor, allowing it to pressurize refrigerant and pass it on through the system. The compressor also uses check valves and other moving parts that allow refrigerant to flow in one direction. What are the symptoms related to a bad AC compressor?
