Do not rule out the T-stat wires being loose or broken and not calling for cool!

Check the 24 volt coil on the contactor for continuity between the 2 wires. I suspect the coil is open. If you have 42 volts ac at the base of the contactor and it ain't pulled in then it is shot. I wrote a tip on this and posted a couple of videos here How it works: Central AC Contactor

    Not 42 volts 24 oops. Actually you should get around 28 vac. Dang I cannot type today. Take the wires off the coil to check the coil sso you won't get a false reading.

New installation should be covered by your contractors. Maybe BBB or local TV station (although I hate all the individuals involved) could help. You might try asking how long the contractors intend to stall before you are forced to resort to the media.

To answer your question, the common wire should be at ground potential. That means zero volts relative to your local ground (cold water pipe or other provision. If you can't trace it, the contractor should be able to. If other circuits are normal, it's in that line which should be off of it's own breaker.

I can't tell anymore than that without seeing your entrance.

Clark vision l 38 auto floor scubber how can i test a 36 volt solenoid

The best way is to put a voltmeter on the forward motor leads first, if no voltage appears or a very low voltage appears when foirward is engaged, the contactor contacts will be the problem,

The contactor windings can be checked with an ohm meter. The resistance should be less than 3000 ohms, Use the reverse contactor windings as a reference for a better idea of the resistance you should see in that unit.

A nonconductive stick can also be used to push the contactor closed, but make sure the scrubber is up abainst the wall with someone at the handles when you do this, as you will be applying more pressure on the contacts with the stick than the windings will when energized and it will likely want to lurch forward and possibly to one side.

Otherwise out of circuit, use a variable power supply with a voltmeter attached and slowly raise the voltage until the contactors close- which should be in the area of 32 to 34 volts. and starting from 36 volts, slowly lower the voltage and the contactor should drop at about 30 volts, maybe as low as 28 in most cases.

IMHO, the forward contactor is the likely source of the problem.

Why won't the compressor engage on my out door a/c condenser unit, when 122 volts are present at the compressor and there is a full charge on the a/c system.

If this a system on a home. You should have 230v to the compressor. If this is a window unit rated for 120v and the compressor is not hot then you mostly have open windings in the compressor and the compressor is dead.

There is power going to the condenser,but it won't turn on

Hi, if you have high voltage going to the unit and it will not fire up, then you are not getting control voltage to it. It takes 2 power sources to run it, high voltage for all of the motors and compressor, but 24 volts from your thermostat to fire it up.I dont know if you have a gas furnace, heat-pump or what. If its a gas split, you will have only 2 small thermostat wires coming into the contactor coil to fire it and close it to send power to all else.You may have a bad stat, broken stat wire, or a faulty transformer, but you have lost your 24 volts somewhere in the unit, and the 1st place to check would be the stat. Please keep me posted.

Hello, My A/C unit will turn on, but it doesn't sound like the compressor is engaging. All 3 fan speeds work, but it pushes ambient air, not cold air. I'm happy to look at this myself, or bring...

Hi Brian, if the compressor is not working, this is your cooling problem. You will need a volt meter to check and see if you have full voltage to it. If the compressor is grounded out, or has open windings, it will need to be replaced.If you can, take it in and have it checked. It may just be the run capacitor. This would be the way to go.

bad motor? faulty thermostat? turn fan switch to on still no motor you'll need a volt meter to figure out what is wrong or hire somebody with a meter who can fix it hvac contractor.
