What is the purpose of the compressor clutch thermostatic switch?
Some vehicles use a temperature-controlled cycling clutch switch to maintain evaporator temperatures. The switch opens or closes the circuit to the compressor clutch, based on evaporator temperature. The switch has a temperature sensing bulb that sits on the evaporator or along the evaporator outlet line.
What is the purpose of thermostatic switch?
A type of switch installed inside security cabinets, vaults, etc. If the temperature within the cabinet or vault rises significantly above its normal value, the thermostatic switch closes, thereby activating an alarm.
What happens if you dont use the clutch switch?
Without the cycling switch to activate the compressor’s clutch, the AC system will not be pressurized correctly, and the system will be unable to produce any cold air as a result. If you begin to notice that the AC system is no longer functioning as it used to, and you suspect that the clutch cycling switch may have a problem,…
When to replace the AC clutch cycling switch?
If your AC is not blowing air as cool as usual or is not working at all, you may need to replace your AC clutch cycling switch. The AC clutch cycling switch is a very important component to a modern vehicle’s AC system.
Where is the clutch cycling switch on a compressor?
The clutch cycling switch is a type of device called a transducer, which changes internal resistance in response to changes in pressure. The clutch cycling switch measures the low side A/C pressure near the evaporator outlet and is often mounted on the accumulator. Step 1: Locate the compressor clutch cycling switch.
Why does my AC clutch cycle on and off?
This switch is designed to make sure that the pressure stays at a consistent level so that the AC can function correctly. As this switch continuously cycles on and off, the AC system operates its electrical contacts which subjects the switch to a high amount of wear.
