Because you are low on freon or bad pressure switch will also stop compressor to stay on.
Either low on freon or the low pressure switch is bad. You are gonna have to put a set of gauges on it. Usually this happens when the freon leaks out of the system. If there is not enough freon in the system, the low pressure switch keeps the compressor from coming on and being burned up.
It should not run with no freon. There is a low pressure switch to keep that from happening.
low freon, bad pressure switch, bad compressor clutch.
Low on freon, faulty pressure switch, faulty clutch. Jumper the low pressure switch with a paperclip (can running, AC on), if the clutch cycles, it's either low on freon, or the low pressure switch is bad.
The most likely reason the compressor is not coming on is because you are low on freon. The low pressure switch will keep the compressor from cycling on because damage to your compressor would result. You can jumper across the low presure switch with the engine running and A/C turned on, ( for short time only) this will provide you with question is my compressor clutch good, or am I just low on freon. The AC compressor relay switch may need to be replaced
You will definitely lose all of your Freon when you replace the high pressure switch. Once the high pressure switch is loosen the Freon will begin to access the system.
You do not want it to run on low freon as it will burn itself up. There is a low pressue switch that tells it not to run if the freon pressure is below a certain point. To make it run; add freon.
most likely it is low on freon. it should have ha pressure switch on the reservoir.
Check the Freon pressure first. The AC compressor will not turn on if the Freon pressure is too low.
Most likely the freon is low, however the low pressure cutout switch could be bad. If it is the cutout switch, the a/c will probably be erratic. The switch cuts out when the low side freon pressure falls to 20 PSIG or below.
You've lost enough freon so that the pressure safety switch will not let the compressor stay on. Just need to add a can of freon.
Fully charged? Bad pressure switch on accumulator/drier? Blow fuse?
It is a low pressure AC clutch cut out switch. It keeps the compressor from running if the system is low or empty of freon.
The low pressure switch could be activated because the system is low on freon.
There is an ac relay, most likely mounted under the hood. There is also a low pressure switch, that will not turn the compressor on if the Freon is too low. Low Freon is the most common cause,
Probably low on freon. The system has a safety low pressure switch that won't allow the compressor to run if the system is low.
there is a high pressure switch on the line or the accumalator, unplug it and place a jumper wire into the connector
Look to see if the compressor is running when the ac is on. If not, then check the Freon pressure, as the compressor won't run if the Freon is low.
1. Freon pressure issues.. 2. Electrical issues.. 3. Pressure switch issues.. 4. Bad clutch wire harness..
check to see if you have enough low side freon pressure and/or if the low pressure switch is working. bypass switch by crossing the wires of the switch with a paperclip to apply trigger voltage to the coil on the compressor,also check to see if there is voltage going to the low pressure switch,if these measures don't work,disconnect the high pressure switch to see if that switch is stuck and shutting off power thru the relay.
The vehicle could be low on Freon. The ac system has a low pressure switch that stops the compressor if the Freon is too low. Looking at the front of the ac compressor, the center of the pulley (clutch) should be spinning when the ac is turned on, not spinning when the ac is off. If this clutch is not spinning then something ( low pressure switch, relay, etc.) is shutting the compressor down.
Any AC, house or car has a pressure switch in the system so that if there is not enough freon in it, the compressor will not come on. The fan will run, but that is all. It is just circulating the air. Nothing will be damaged in the system running it without freon.
There is a pressure switch that runs the clutch. If there is not enough freon in the system the switch will never allow the clutch to turn on.
Locate the low pressure cut out switch, unplug the wire connector, using a paper clip jump across the two connections in the electrical plug. This will by pass the low pressure switch and allow the AC compressor to run. THIS IS A TEMPORARY PROCEDURE! Once you have filled the system with freon remove the jumper wire and plug the connection back in to the low pressure switch.
