If your air compressor reset button keeps tripping, it’s probably because your air compressor is too hot. If the button is tripping then the motor is already getting hot. If a compressor were to overheat without the presence of a reset button, the motor will become damaged and lead to serious problems down the line. Its main purpose is to automatically turn off the air compressor’s power when it overheats. The reset button is there to provide the user with safety. In some cases, it may be located inside the wiring of the motor. Solution: All you need to do to get rid of this problem is clean your car AC’s condenser coils, especially the No products found.An air compressor’s reset button, otherwise known as the thermal overload button or safety switch, is located on the end of the air compressor or on its side. This issue can happen anytime although keeping your car AC system idle can escalate the situation. The reason behind it is that now the drying process gets delayed and your AC compressor has to work harder to cool down your car. To summarize, when the condenser coils (especially the evaporator coil ) are too dirty with dirt, debris, and dust, the compressor can cycle on and off too quickly. Hence, the pressure cutout leads to your compressor cycling on and off at idle. This triggers the high-pressure cutout to prevent any further damage to your compressor. Even the subcooled liquid will come out at a higher temperature. However, if your condenser is way too dirty, it can prevent the refrigerant from cooling. #2 Condenser is Extremely DirtyĬondensers are bound to get dirty with regular usage. This will trigger fluid supply through the AC system and keep all the AC parts active and in good health. As a precautionary measure, you should keep the car AC on for at least 30 mins per week. Note: You will need to buy an AC recharge kit to refill refrigerant into your car AC system.Īnother thing to take away from here is that keeping your car AC system idle for too long isn’t a good idea. Here’s a YouTube tutorial to help you recharge your car AC: Once your car AC system is properly charged, the issue will be solved. Check the pressure to confirm that low refrigerant is the problem.Check for and repair leaks (if any) that could result in loss of refrigerant.There are a couple of steps that you need to follow to fix this condition: It is pretty common and the good news is that you can fix it yourself. Solution: This is also called a low charge problem and the best thing about this is that your compressor isn’t broken. This happens quite frequently in times of winter when you probably wouldn’t be using your AC much. Keeping your car idle for long durations at a stretch can lead to a lot of refrigerant loss. This can even lead to a catastrophic compressor failure which would require you to replace the entire system.

It will be harder for your car AC to cool down the car’s temperature. That too can lead to your car AC compressor rapidly cycling on and off at idle.Ī lack of refrigerant indicates that less oil is circulating through your AC system. The reverse of this situation is called high-pressure cutout which can be caused due to too much refrigerant in your system. The pressure will stabilize in one or two seconds and the compressor will get engaged once again and the cycle repeats. Now, triggering the low pressure can turn off the compressor. This can cause the pressure to drop when the AC compressor gets engaged. Some of the refrigerant can be lost over time due to your car compressor AC being idle or due to some leaks. Here are the top 3 reasons why a car AC compressor can cycle on and off non-stop while idling along with ways to fix the issue: #1 Not Enough Refrigerant (Freon) Your car AC compressor short cycling non-stop can overwork the AC system and can escalate to more serious issues. If the AC compressor is going on and off non-stop, that should be a concern to you.
