My AC is broken, is it a discouraging appealing contactor? When I turn my thermostat to cool the furnace fan runs...
When I turn my thermostat to cool the furnace fan runs and blows room temp nouns, but the condenser does not turn on. I pulled the service disconnect out and taped down the appealing contactor then put the disconnect support in...the condenser run so I shut it back down since I know you should not run it similar to this (I just needed to see if it even ran...). My plan is to subsequent check to see if I have control voltage from the furnace to my alluring contactor. How do I do this? Is it 24V? Is it AC or DC? I have hear you have to check it at the coil and not the contactor or you will read a phantom 24V (I'm confused nearly this)? Any ideas? If I do draw from a 24V reading then it must be the charming contactor correct? If I don't get a 24V later I am shorting out somewhere inbetween my furnace and my condenser correct?
Thanks for your comments

hi Erik, it can be a number of things that you involve to check out. first of all remember you enjoy 220volts at the contactor and shoul be carful with it. is the compressor making any rumble when trying to start? is it hot? how are your pressures,low and high? are you sure you enjoy 220 volts?
This is only slightly related, but it's more probable that there's an open circuit than a short circuit. A short circuit would probably trip a circuit breaker or impose something to burn out.
And I'm not sure about the phantom voltage, but one could grasp the proper voltage at a light switch (and at the fixture) even if adjectives the connected bulbs are burned out.
There may be some information at the manufacturer's website.
Good luck.
Answers: You have transformer voltage because the inside works so check the contactor coils for continuity. You can desecrate the thermostat by rubbing the 2 wires together even though it is low voltage 24volts ac. Check the small wires coming out to the contactor coil. Should be 28 volts ac. Like I said if the contactor coil is open later you needs another contactor.Pictured below is a single pole contactor. The low voltage coil on it is on respectively side of it. Notice the double male connectors. to be exact one side of the coil only. The other side is not pictured. They mount it surrounded by double spades just to verbs folks I believe.
