If the Freon is low the pressure drops and the switch will not see ground. Add Freon as needed.

SOURCE: Ac compressor won't kick on

Just had the same issue and posted. Just found the solution is the control module in the dash. Went to the junk yard since new is expensive on these units. Plugged new unit in, was able to charge a/c now blows cold as ice.

SOURCE: I cannot locate my low pressure switch on 1995 Corsica.

First of all, from the discharge port of compressor to the condenser(the device in front of the radiator) from the condenser to the metering device is all the high side or high pressure. From the metering device through the evaporator including accessories back to intake of compressor is the low side or low pressure.It is important to know that entrained in the refrigerant is oil for lubrication. The combination of pressure and oil could be a safety and environmental hazzard. I know on older GM models one could short out low pressure switch by jumping the low pressure switch with appropriate gage wire. This would temporarily permit one to add aditional refrigerant to system.The job of the low pressure switch is to protect the compressor from burning up due to lack of refrigerant by shutting the system down.. Now, if the refrigerant is low it had to escape, meaning a leak.(refirerants don't just wear out)Refrigerants are notorious to being determental to the environment. Older refrigerants contained hydrocarbons that destroyed or reduced the ozone levels to reduce this from happening strict laws of handling and recovering a/c refrigerants were enacted & exhorbitant costs were placed on the offending refrigerants.In order to save some some money some untrained or knowledgeable people are continuing attempting to repair their systems risking injury like permanent eye injury.Is it worth it? No one (I believe ) intentionally desires to be hurt.However, by attempting to do something that you haven't been trained on can make you more susceptable to injury or accident. An in a instan one could trade off perfect vision to partial or even total blindness.This is not to just to scare you but gives you an opportunity to weigh all the decisions prior to attempting something one might be unfamiliar with.Most of the accidents I've witnessed at home and work were individuals taking short cuts,hurrying or attempting something unfamiliar with.Not all accidents fall into this category but be aware rehab is no fun and often not totally complete. Lets not compromise your safety and the well being of our environment.

SOURCE: 1998 Ford Explorer a/c not working properly

Had the same problem on 98 Eddy Bauer we have. Have you noticed that it has a tendency to belch out hot air and the blower speed slows down mostly when you accelerate or give it a little more gas to climb a hill or an overpass or even pass somebody? If this is the case there is a pressure switch that's hooked into the intake manifold were it can sense a drop in pressure and when it does it drops the ac clutch out and slows the dash blower down till the pressure comes back up. JUMP IT OUT. All your problems will go away. Thats in there to unload the engine during acceleration and heavy loads and after the switch ages it gets trigger happy and lazy about closing to bring the ac back on.

SOURCE: air conditioner relay location 2004 passat

hi,
the a/c pressure switch is located to the left side of the condenser radiator, as you stand in front of the vehicle. you may have to remove the bumper in order to get access to this switch.
there are 2 relays dealing with the a/c , numbers 16 and 17, on the relay plate at the drivers knees, the plastic panel will have to come down. 16 is the clutch relay and 17 is a/c control module.
hope this is of some help

I have a Arctic King through wall AC model MWW-12ERN1-MI0 and the compressor will not engage to cool the air. Can anyone help me diagnose and fix this problem?


On the ac unit electric section, check for power at Y1, should have power, possibly to x or c ( common terminal).
Check for power across the compressor contactor, should have power or something is open such as a pressure switch or compressor protection. If there is control power at compressor contactor solenoid ( 24 volts control), then check for supply power on line side of contactor, then on load side of contactor (supply voltage e. g. 230 volts. If all voltages are present, then check the compressor for opens and electric continuity.
CAUTION: electricity is dangerous, can kill and/ or cause fires. Do not attempt if not aware of safety procedures.

A/C Compressor won't turn on Can jump compressor from battery and compressor comes on & cools. Hi pressure switch checks out ok and 12 volts going to hi pressure switch no voltage to compressor


the high pressure switch kicks the compressor off when the pressure rises, the low pressure switch kicks it on, check that switch, unplug the wire and use a continuity meter to see if the switch functions, also check for power getting to the plug itself

Bought this LG unit (LWHD7000HR) summer of 2010 and it worked fine - used very rarely. Did not use heat in winter either. Went to turn it on this summer and it does not cool. Fan operates but compressor...


Unplug the a/c and check the control panel of your a/c. Unscrew the control panel to expose the wires and terminal lugs.Check for lose wires or terminal lugs or defects from the compressor capacitor. If all are OK try adjusting the thermostat switch to make the contacts work. If the capacitor is damage replace it and replace any damage terminal lug. If the compressor still does not work, check the overload and the compressor resistance. If overload is open, replace it and check compressor amperage. If the compressor amperage is high, you have to replace the compressor, vacuum, and recharge freon.

I have a 02 lincoln ls . the air conditiong is not working . i took it to a local shop they check the compressor, fuses, relays, pressure swithches, all is checcking out good. They jump the compressor...


YOU COULD HAVE OPEN OR SHORT IN THE BLACK YELLOW WIRE GOING TO AC COMPRESSOR CYCLING PRESSURE SWITCH. CHECK FOR A SHORT OR OPEN IN RED YELLOW WIRES AT THE AC PRESSURE CUTOFF SWITCH. USE VOLT METER AND CHECK FOR VOLTAGE AT BOTH SWITCHES. PROBLEM COULD BE IN THE EATC MODULE THAT SEND POWER TO PURPLE WIRE THAT FEEDS THE AC PRESSURE CUTOFF SWITCH AND AC CLUTCH CYCLING PRESSURE SWITCH THEN FEEDS THE AC COMPRESSOR CLUTCH SOLENOID.

Whirlpool dyer will not work, have replaced the board but


Sounds like the control panel may be dead. If you cannot get any lights to come on at all on the front panel, its probably a goner. You can check the voltage coming out of the control pc board via the schematic inside the dryer panel. I have this same exact problem. I replaced the control board 3 times because the panel seems fine if i plug it into an external power supply but will not work when plugged into my dryer. I have my jumpered and running off of a circuit breaker. I have checked every part in the entire unit. That was over 2 years ago. I still need to get a control panel and see if it fixes mine but after dropping $130 on the control board, i feel i could buy another dryer with the $200 they want for the control panel. Also this dryer seems to streak my clothes with brown or rust colored spots. The dryer is spotless inside. I even took off the rubber seal because i thought the glue is what was possibly doing it when it heated up but that didn't help either....This dryer sucks.
