Have you checked the contactor coil voltage? It should be 24V. It will be the smaller wires either on the top/bottom of the contactor or on the sides of it. Turn the 240 V off prior to checking the low voltage to ensure you do not get electrocuted. If you have voltage at this point, then the contactor coil is defective and you will have to replace the contactor. About 25$ US at most electrical supply houses.

Multiple clicking sounds coming from AC unit before AC unit turns on or before furnace turns on.


the is a 24v wire that feeds from your thermostat to your unit, inside there is a contactor that engages, this makes a click sound as it really is a basic mechanical part the makes metal touch metal to allow current to flow through the system, perfectly normal, your hearing the low voltage engage the highvoltage at the contactor.

I need to run a contactor ( 40 amps 3 phase ) with the help of thermostat..i have connected L1,L2 n L3 and output coneccted in T 1 T2 T3 . now how to connect A1 and A2 .... i want that contactor should...


1) Copy following links for illustrations showing timer controlling contactor in 3-phase environment:
http://waterheatertimer.org/How-to-install-3-phase-timer.html
http://waterheatertimer.org/images/3-phase-timer-diagram-24Vac-865.jpg

2) Substitute thermostat instead of timer for switching control.

3) I don't know what thermostat you have, or if it's functioning or the rating.

4) Which contactor do you have?
Do you have a 3-phase contactor??
Or two-pole single phase contactor?

5) Match thermostat output voltage with contactor voltage:
Thermostat output is 24 volt? Then use 24Volt coil on contactor.
Thermostat output 120 or 277 > then use contactor with same coil rating.

6) More information is needed.
I don't understand description of your wiring.
Add a comment and compare with illustrations sent, so I can visualize ... or attach photo and/or give product numbers so maybe I can locate wiring diagrams.

Ruud compressor relay not working a/c


Hello,im assumimg you are referring to the contactor coil on the oudoor unit. First you must verify if the coil is receiving 24 volts from the thermostat at the coil terminals, if not there is a problem with the low voltage circuit, possibly a a open thermostat wire or a fuse blown on the indoor control board. If ther is 24 volts at the contactor coil and it does not engages then the contactor coil must be replaced

Central ac compressor keeps running


Sounds like the contactor is stuck. Turn the power off on both units and remove panel on condenser. Pull out on the contactor if engaged. Likely still needs replaced, it's going to happen again.

The fan does not run


I am assuming that this is the condenser(outside unit)? You will need a multimeter, take off the four screws and at the contactor measure and see if you have voltage. I am assuming the contactor is engaging, if not push in contactor. Fan and compressor should come on, if it does the you will have to check for 26 volts on the contactor where your thermostat wires come in, if you have the volts then the contactor is bad. Hope this helps Tim

Outside unit runs continuously, even when system is off.


On A/C units, there is a low voltage line that leads to a contactor, which engages to close the high voltage circuit to the condensor unit. Over time, the accual contacts in the contactor can weld themselves together. Try shutting off your furnace breaker but leaving on the one for the outside condensor unit. If it still runs, your contactor probably needs replaced. Contact a licensed electrician or HVAC contractor and tell them you think your contactor is in need of replacement. Is a fairly simple and quick replace, but the contactor itself is not cheap.

Have a Ruud AC unit the problem I have after installing a new condenser fan motor when I throw the circuit breaker the unit will not turn on but when I push the contacts on the contactor in manualy the fan...


The contactor engages from low voltage power from the thermostat as does the outside condensing unit. You may have blown the low voltage transformer or have a loose thermostat wire. Check line voltage(220 volts) to the transformer. Check load voltage(24 volts) from the transformer. If no voltage out,replace the transformer. If you have voltage out(24) check the thermostat wires and the thermostat. If you have a digital thermostat there is a 5 minute delay in the thermostat after power is restored before it activates.

Is the contactor engaging? Make sure it is getting 24v. If not, check the low pressure safety, outside thermostat (if you have one) and the defrost board. Follow the low voltage from the thermostat to all these controls, up to the contactor. Check the thermostat too. If you need a walk through I can help, if you have a volt/ohm meter.
