What is the Thermal Overload on an Air Compressor?
The thermal overload, also known as the overload relay or thermal block, safeguards the compressor from damage by monitoring electric motor current and tripping the relay if it gets too high for too long.
Causes of Compressor Overload
- Overheating due to continuous operation
- Failed components like capacitors or wires
- Leaking oil or burn marks indicating a malfunction
How to Test and Reset Thermal Overload
Testing the overload involves assessing components like windings, capacitors, and amp draw. If tripped, reset the overload to restore normal function.
Signs of AC Compressor Overheating
- Inefficient cooling
- Loss of cooling capacity during peak usage
- Possible emergency AC repair needs

Preventing Compressor Overloads
Regular maintenance, timely repairs, and avoiding continuous usage help prevent overheating that leads to compressor shutdowns.
Frequently Asked Questions For Thermal Overload Ac Compressor : Preventative Measures
What Is The Thermal Overload On An Air Compressor?
The thermal overload on an air compressor, also known as the ‘thermal block’ or ‘thermal relay’, safeguards the compressor from damage by monitoring the motor’s current. If the current exceeds safe levels for an extended period, the overload relay trips, preventing potential harm to the compressor.
How Long Does It Take For Compressor Overload To Reset?
The time it takes for a compressor overload to reset can vary depending on the specific model and brand of the air conditioning unit. Generally, it can take anywhere from a few minutes to several hours for the overload to reset itself.
It is important to note that if the overload continues to trip frequently, it may indicate a more serious underlying issue that requires professional attention. Regular maintenance and inspections can help prevent compressor overload and ensure optimal performance of your air conditioner.
How Do You Reset The Ac Overload?
To reset the AC overload, follow these steps: 1. Turn off the AC unit and unplug it from the power source. 2. Allow the unit to cool down for at least 15-20 minutes. 3. Locate the overload reset button on the compressor or control panel.
4. Press and hold the reset button for 3-5 seconds. 5. Plug the AC unit back in and turn it on. Remember, resetting the AC overload should only be done after troubleshooting and addressing any underlying issues. If the overload keeps tripping, it’s best to consult a professional HVAC technician for further inspection and repairs.
What Happens When Ac Compressor Overheats?
When the AC compressor overheats, it can damage the system and reduce cooling efficiency, requiring emergency repair. Running the system continuously can lead to overheating and eventual shutdown. Preventive maintenance and addressing underlying issues can help avoid compressor overload.
Conclusion
Understanding and addressing thermal overload issues in your AC compressor is crucial for efficient cooling and preventing costly repairs. Regular inspections and prompt action can extend the life of your system.
