The refrigerant pressure switch monitors the pressure in the air conditioning system to ensure it is operating properly. If the pressure gets too low, the switch turns off the air conditioning system. This saves the compressor from running without lubrication and sends a signal that there is a error in the AC system. There are a few symptoms you should look for if you suspect a bad or failing refrigerant pressure switch:
1. Air conditioning works intermittently
When you turn the air conditioning on, does it seem to cool the vehicle down then stop working? Or does it not work all of the time, just at random times? This means the switch may not be working correctly or have an intermittent failure. As soon as this happens, contact a professional mechanic to have your refrigerant pressure switch replaced so you can be comfortable in your vehicle.
2. Air conditioning not working properly
The air conditioning in your vehicle may not seem to get cool enough, causing you to be uncomfortable on a hot day. This can be caused by many factors, and one is a failing refrigerant pressure switch sensor. In hot summer months this can be a safety concern if the outside temperature gets too hot. A mechanic can properly diagnose the issue, whether it is the switch or a low charge in the refrigerant.
2. Noise coming from the AC system
If a high pitched sound comes from the air conditioning system when it is on, this is a sign the pressure switch may be going bad. The switch could be rattling against different parts in the engine compartment, so it is important to have this looked at before other parts are damaged.
4. Blowing warm air
If no cool air comes out at all, it could be a switch problem or another issue within the air conditioning system such as low refrigerant. A mechanic will check the pressure in the system to ensure it has the correct reading. If it is too high or too low, the sensor is most likely failing. In addition, they can read any codes the computer puts out to positively diagnose the problem.
If your air conditioner is not working properly, noises are coming from the system, or it is blowing warm air, contact a professional mechanic. The refrigerant pressure sensor switch is an important part of keeping you comfortable on hot summer days so it should be repaired as soon as possible.
