If a compressor fails, it may feel like the whole system has stopped working. Appliances such as HVAC systems and refrigerators, as well as other types of machinery, have internal operations that can be greatly affected by an improper functioned compressor. If left unattended, they can cause more damage in the future.

Issues with Power Supply
The reason your compressor was not working could be as simple as getting no power. Firstly, check if the compressor is plugged in and has access to electricity. There could be several reasons stopping it from receiving power, such as:
- Tripped Circuit Breakers: On certain occasions, excessive load or power spikes can cause the breaker to be automatically turned off. Reset the breaker and check if that enables the compressor to function.
- Loose Wires or Connections: Inspect the power wires and terminals for potential breakage. Due to loose connections, power to the compressor may not be uninterrupted.
- Power Switch: The compressor’s power switch should be confirmed to be in the ‘on’ function.

How Can You Tell If the Start Capacitor Is the Problem?
If your compressor doesn’t start, the problem may be with the start capacitor. This component ensures proper functioning of the compressor when power is applied. If the capacitor is initiated incorrectly, the compressor will not begin its cycle. Start visually inspecting the capacitor for obvious signs of failure like swelling, leaking, and burns. If any of these signs are present, capacitor failure is likely, and is due for replacement.
Check the Compressor’s Relay and Overload Protector
The overload protector works together with the compressor relay to provide smooth operation of the compressor. If either of these parts is faulty, the compressor will not turn on or off before the cycle is finished. Check for the following:
- Compressor Relay: The relay to the compressor turns the compressor’s power on and off. If burned, check for the cuts that show the relay turned on.
- Overload protector: This helps prevent the compressor from excessive heating. If malfunctioning, the compressor will cut power at random times for no reason. An electric test with a millimeter can show if the protector is working properly.
How Can a Refrigerant Leak Potentially Cause Problems?
Loose refrigerant is one of the common issues to make compressors work too hard to perform cooling functions. First, check for damages on refrigerant lines. If no damage is found, using leak detectors or soapy waters to spot leaks out may be necessary. At this point, the refrigerant needs to be replenished, and the leak should be constant to avoid complications.
Listen for Unusual Noises
Other problems that may be presented are mechanical ones, which stem from the strange or loud noises that a compressor could produce. The fridge may produce various sounds that appear concerning, for example:
- Clicking Sounds: Such sounds may suggest a problem with a relay or that the compressor is attempting to start for some reason.
- Buzzing or Humming: The buzzing sound could mean the motors going to the compressors are already failing to work, and their only way to show this is a buzz.
- Grinding Noises: The most significant noises are rattling and grinding, which could hint at the internal failure of the compressor parts.
How Can You Prevent Overheating?
Another vital component to observe is the area of ventilation regarding the compressor. As with any machine, the compressor, and in particular the one found in air conditioning units, needs adequate airflow to cool itself. If surrounded by dirt and debris, the apportion may overheat and shut down, which is a safety mechanism. Sufficient clearance around the compressor should be maintained for optimal airflow into and out of the compressor.
How Long Should You Attempt To Fix It Before Seeking Help?
If you have performed all of the above-mentioned troubleshooting steps and the compressor does not work, calling an expert will likely be necessary. Some trouble areas, like a burnt-out motor or an intricate electrical system failure, need specific skills. Feel free to speak to professionals if you have doubts or cannot find the cause.
