What does a low pressure switch control?

What does a low pressure switch control?

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.

Is there a corvette clutch that will not kick?

I have a 1993 corvette that the a/c clutch will not kick on… 92 corvette with c68 and the clutch will not engage. The DK 92 corvette with c68 and the clutch will not engage. The DK BLU wire from the programmer to the A/C high pressure cut-out switch has 0 volts and … read more

When to close the AC clutch cycling switch?

When it is detected that the pressure has dropped below a certain threshold, the switch will activate allowing pressure from the high pressure side of the AC system to enter the low side and equalize the pressure. When the pressure returns to normal, the cycling switch will close.

Where are the low and high AC pressure switches located?

The low-pressure side switch is found before the AC compressor, while the high-pressure switch comes after the compressor. Most AC pressure switches are found within the engine compartment, but some manufacturers put them elsewhere. A look in your service manual will show you the appropriate location for your model. AC Pressure Switch Function

Where is the clutch on an AC system?

It is mounted in the low pressure side of the AC system and its purpose is to detect the flow of refrigerant in the system by measuring the pressure.

Why is the clutch on my Corvette not working?

• Freon pressure in the high and low sides should equal each other after the A/C system has come to rest. • Freon pressure will fluctuate depending on ambient temperature. • Proper clutch operation depends on correct refrigerant charge, low freon charge will shut off A/C compressor operation.
