Where is the AC switch located?
Your AC pressure switches are located on both the high and low sides of the unit. These switches monitor and check the pressure of the refrigerant on both sides of the system, with separate switches for both the high side and the low side, which both serve to prevent pressure issues causing damage to the compressor.
Where is the low pressure sensor?
The low-pressure cutout sensor can be found on either the high or low side of the system and is used to disengage the compressor clutch if pressure gets too low.
How do you jump a low pressure switch on an air conditioner?
To check/jump the low pressure switch, don’t run a wire from the battery. Unplug the plug on the low pressure switch. Use a stiff piece wire bent in a U shape to jump the plug (should be just two wires) stick your jumper wire in the plug. Even a paper clip will work.
What does AC low pressure switch do?
The low pressure switch monitors the refrigeration system for a loss of refrigerant charge, and may also be helpful in stopping the evaporator (indoor) coil from freezing up due to a dirty filter or low airflow over the coil.
Where is the pressure switch on an A / C compressor?
The A/C pressure switch is mounted on both the high and low sides of your A/C. When the pressure in your A/C rises or lowers too much, this switch turns off the compressor to protect it and the rest of the system from damage. This switch is crucial for proper A/C performance.
When does the AC low pressure switch turn off?
Now, as we discussed earlier, the AC low-pressure switch turns the system off if it senses that the pressure is too low.
Where is the low pressure sensor on an AC unit?
The AC low-pressure sensor is located at the line that runs from the compressor component of the system through the evaporator or the firewall of the system, up to the condenser on the low-pressure side of the air conditioning system.
What’s the difference between high and low pressure AC switches?
As I have already mentioned, there are two switches mounted on each side; the high and the low. The one on the high side is called the high-pressure switch, and the one on the low side is called the low-pressure switch. What does an AC low-pressure switch do, and why is it important?
