thermostat could be bad, or location of it, air flow over it.
Sound like you are low on Freon causing the compressor to cycle on and off. If you are low of Freon then you have a leak somewhere.
Usually on or near the receiver/dryer. If the refrigerant level is too low, the switch will turn off and not allow the compressor to run.
turn switch off and on
an automotive AC has a thermostatic switch that cycles the compressor on and off in order to control the temperature within the evaporator core and keep it within a certain range, much like the thermostatic switch in a refridgerator.
Hi the compressor has a device usually a pressure switch that on off loads the head inlet compression valve system. With a screw compressor it is usually a diaphragm operating a piston that open and closes the inlet to the element
Refrigerant filled within compressor, condenser and evaporator has leaked not allowing thermostat to switch off the compressor or in rare cases thermostat itself is damaged.
I'm not sure why you would want to disable this.. There is an on and off switch in the trunk on the passenger side. In the off position the air compressor will not operate.
On the dryer, there is a cycling switch which also cuts off the compressor when the preasure is low. Perhaps the switch is defective. GoodluckJoe
Sounds like either a defective relay or relay wired incorrectly switch the wires over.sounds like wires are on backwards
It is possible that the circuit breaker for the compressor unit is thrown (switched to "off"). Go outside to the compressor unit and follow the big cable up to the circuit breaker panel on the wall. If it is off, throw the switch to "on." If that is not the problem, something is probably wrong with the compressor unit. Turn off the breaker panel and call a repairman.
More than likely it is low on refrigerant and the compressor is kicking off on the low pressure switch. After it is off for a few seconds the low pressure switch resets and starts up again, runs a few seconds and off again. Continuous cycle of off and on.
