AC Pressure Switch in Chennai
The pressure switch protects the compressor by switching it off when refrigerant pressure is too low or too high, and on many cars it also triggers the condenser fan.
What the AC pressure switch does
Binary switches cut the compressor at low and high pressure; trinary switches add a middle stage that turns on the fan. Newer cars use a pressure sensor that reports the exact pressure to the engine computer.
OEM or aftermarket?
Switches and sensors look similar but have different thread sizes, pressure ranges and connectors – match the original.

Signs of a failing AC pressure switch
- Compressor does not engage even with correct gas pressure
- Compressor cycles on and off rapidly
- Condenser fan does not come on with the AC
