Any one of several things can cause this,verify the breaker for the unit and the disconnect switch outside are both on. Then check that the fuses outside are good. With a meter, measure the voltage between R and Y at the air handler if you read nothing the outdoor unit should be running ( along with the indoor fan). If you read 24Volts between R and Y the thermostat is not telling the unit to start and you should look there. The control voltage for the outdoor unit (24 volts) comes from the indoor unit. So if that is off, or if the transformer is bad or if there is a blown control fuse you will get nothing. If the control transformer is cold to the touch, that can be a good indication your problem lies there. If all of these things turn out correctly you have a tripped safety switch in the outdoor unit or if the compressor feels hot to the touch but won`t run the run capacitor is probably the problem. If so turn the outdoor unit off until it can be replaced.

You went to put freon in your suburban but could only afford one can but the compressor didnt turn why?
The compressor wont turn if the freon levels are too low! It has a cutoff so if the freon all escapes the system the compressor wont be damaged.
Trans am air conditioning wont work?
The A/C Compressor may not be charged with frion if the A/C Clutch does engage, or it may not engage due to fact it's not sending 12v to the electronic wiring. First start the engine and turn on the A/C, watch if the clutch on the compressor engages or not.
Why wont the air conditioning compressor cycle on a 1998 escort?
It sounds like you are low on refridgerant, i would have your A/C lines inspected, and maybe try to recharge it, could also be a bad A/C pump.
You have freon in the ac system on a 98 windstar but the compressor wont turn on?
Fully charged? Bad pressure switch on accumulator/drier? Blow fuse?
1989 Dodge Dakota-My air wont come on the fan wont even turn on so what could the problem be?
You may have a leak in the system. When the refrigerant level drops below a certain point the fan and compressor will not engage.
Check engine light wont turn on on a 2000 Mazda mpv?
Burned out sending unit
Your turn signals wont work on 2000 dodge durango but checked all the fuses?
Could be the flasher unit.
If the ac compresser sensor is not plugged in will it make your engine run hotter?
No...That sensor is a pressure sensor.(located next to the condensor) It will not let the compressor run if the pressure is to low or to high,so the compressor wont be damaged. If it is unplugged the compressor wont come on at all.
What are the effects of shampooing and conditioning hair?
The effects of shampooing and conditioning your hair is it wont be greasy, will be easier the style and will have less knots.
What could be wrong with your ac in your 93 Chevy z24 it blows perfectly it just wont get cold?
If the air conditioning pump in the 1993 Chevy Z24 blows perfectly, but won't get cold, it is possible that the Freon needs to be recharged in the air conditioning unit. This can usually be done for about $40 by the consumer.
Could body contol module not allow compressor to run on a 93 buick lesabre?
yes it wont allow your compressor to run
Diagnose air home conditioning fan wont shut off?
Here are some reasons why this may be happening: * The thermostat is turned to a temperature which is lower than the unit can make the air cool down to. It is worth trying this: turn up the temperature by say 10 degrees. If, after a few minutes - say 30 minutes - the fan in the unit switches off and after another say another 15 minutes it comes on again, then it is likely that the unit is working but is not powerful enough to make the air as cold as you wanted. * The unit has lost all its refrigerant so is not cooling the air but the thermostat keeps calling for it to cool the air. * The unit's compressor pump has seized-up or failed in some other way, so is not cooling the air but the thermostat keeps calling for it to cool the air. To be able to investigate either of the last two reasons you would need to call a Heating, Ventilation and Air Conditioning (HVAC) technician to use his test instruments, tools - and experience - to diagnose the problem and advise you what can be done to fix it.
