Where is the AC pressure sensor located?

Where is the AC pressure sensor located?

The AC pressure switches are located on either side of the AC unit. You will find one switch on the high side and another on the low side. The low-pressure side switch is found before the AC compressor, while the high-pressure switch comes after the compressor.

Where is the low pressure switch located?

The low side service valve is located in the line that runs from the compressor through the evaporator (firewall) and up to the condensor on the low pressure (suction) side of the system.

What is the purpose of AC pressure switch?

The AC pressure switch is a safety switch mounted on the upper and lower sides of the air conditioning system. When the pressure goes up too high or falls too low (on the side of the system where the sensor is mounted), the switch turns off the compressor to avoid damage.

What if my AC pressure is too high?

When the pressure of the AC system is too high this might indicate a leakage or diminishing amount of refrigerant, both of which require immediate attention. If the AC temperatures are abnormally warm, this could indicate an issue with the compressor that might need repair or replacement.

What does an air conditioner pressure switch do?

How do you change an AC pressure sensor?

Part of 1 of 1: Replacing the refrigerant pressure sensor

1. Materials Needed.
2. Step 1: Locate the refrigerant pressure sensor.
3. Step 2: Disconnect the negative battery cable.
4. Step 3: Remove the sensor electrical connector.
5. Step 4: Remove the sensor.
6. Step 5: Install the new sensor.
7. Step 6: Reinstall the electrical connector.

How does AC low pressure switch work?

The AC pressure switch is a safety switch that is mounted on both the high and low sides of the air conditioning system. Depending on which side of the system the sensor is mounted in, when the pressure rises too high or drops too low, the switch will turn off the compressor to prevent damage from occurring.
