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.

Wiring- Connecting wiring on replaced fan motor


Your new fan motor should have a diagram with it or at least printed on the side of the motor, that will help a lot from your end. As for me, I don't know what unit you have, so I will try to help you with just the basics.

Your old motor probably had 3 wires. One went to the contactor, that is the "Line Voltage", one went to the Common terminal on the old capacitor (COM), that's the other "Line Voltage" wire, and the last one went to the "FAN" terminal on the old capacitor. The reason the old capacitor looks different is because it works for both the compressor and the fan motor (split capacitor). You still need this hooked up for the compressor to work.

The new fan motor.
These vary in brands and wiring so I can not tell you the colors without knowing exactly which motor you have. On the new motor wiring diagram, you should see the "Line Voltage" as described above that 2 of the wires are ran to each other (just on the diagram, not wired together on the unit). This is your power wire that goes to the contactor on the unit, usually black, and your Common wire that runs to the capacitor. You can still run this wire (COM) to the common terminal on the old capacitor since you still have to use the old capacitor for the compressor and the common terminal should still be jumper-ed from the contactor to the (COM) terminal. Then you will probably have 2 wires for the new capacitor, usually Brown and Brown/White. These wires run to each side of the new capacitor and doesn't matter which terminal. Then you will take a new jumper wire from the (COM) terminal on the old capacitor to the terminal on the new capacitor that has your Brown/White lead. Make sure you secure the capacitors inside the unit so not to touch anything surrounding them. Your new motor might also be a "Reversible" motor that has reversing wires also. Again, your new motor diagram can tell you how to hook these up. You have to have it spinning the right way, most of the time it is CCW (counter-clockwise).

I'm sorry I can't be any clearer on this, but without knowing the brands, models, etc, I'm in the dark. If you need any additional help, I would be glad to help! Good luck and hope you get to cooler days!

I need a three phase wiring diagram for 8145-20 model timer.


8145-20 240Volt Paragon timer is not 3-phase.
Clock motor is 240V.
You need a transformer to convert 3-phase to single phase 240V to operate timer.
Then timer outputs can control 3-phase power using 3-phase contactors
Contactor below is 3 phase with 240V coil

Not sure need a diagram for payne 2 ton or 21/2 ton yac108c. The service techs tore it off need it to install a blow motor.


Actually you can change it without the diagram. Simply cut the wires on the motor and leave the terminal ends attached to both the contactor terminals, and possibly the cpacitor if present. Then install your new fan motor replacing the leads from the old one with the leads from the new one.

But if the new motor has different colored leads, usually the brown leads are attached to the capacitor (it doesn't matter which terminal the leads go to, as long as there are only two leads and it is just the fan's capacitor). And then attach the other two leads to where the other two old leads are. (Naturally removing or swapping new wires to where old ones were.)

How do you change the alternater belt on a 2001 Galant?


My apologies for the delayed response. I am going back to answer unanswered questions.
1. Yes, you have to take the other belt off to take this belt off.
2. I use a wire brush to get melted rubber out of the grooves on pulleys with grooves. I use a wire brush then sand paper to remove melted rubber of smooth pulleys.
3. You should always replace both belts instead of just one.

CLICK on the following LINK. I beleive it has the Diagrams for your Belts that you will need.

My outside a/c unit fan stopped working. When I


By saying the condenser fan is not working as well, I have to ask is the contactor making any kind of noise?. If the contactor is not making noise, look for some smaller wires going to the contactor. These are the low voltage wires that send 24 volts to the contactor. Make sure the thermostat is turned on, set it for a temperature lower than the current room temperature. Are you getting voltage to the contactor? If the answer is no check the W wire at the air handler and at the thermostat. The G wire runs the inside blower only. This is why you can put the fan in the ON position and not have the compressor running all the time. If you are getting voltage at the contactor turn the power back on at the compressor, take a sturdy insultaded rod, very dry wood or plastic remember electricity can kill damp wood can conduct electricity. Look for a small bump in the center of the contactor. Press it with the rod and see if the compressor turns on. If it turns on when you press this point on the contactor and off when you release it then the low voltage side of the the contractor is bad. If the bump is pulled in and the unit is not running take the multimeter and carefully check to see if your are getting 240 volts across the two bottom connections and then 240 volts across the top of the connections. If you are getting 240 volts on one side only the the contactor is bad and you need a new one. Turn off ALL POWER this is the breakers for both the compressor and the furnace. Again make sure the power is off. Make a diagram of the wire positions, then disconnect them. Remove the contactor and take it to an electrical supplier or an HVAC parts supplier and get a new one. Reinstall it and reconnect the wires. Turn the power back on and everything should be working again.
Good Luck

I am a ac tech, and i was working on a old carrier unit, wich had no schematic diagram. I need it in order to get the compressors going. if i give you a model # can you please provide one. roof top ac...


you aren't an ac tech number one but i shall overlook that . your question is llike will the sun come up in the north or the south tomorrow. obviously in the east as it has since the earth was created. anyway. all compressors since the beginning of time wire up the same .a wire commonly referred to as the common goes from the contactor to the compressor. usually black in color, hence the old coloqualism Blacks are common. the run wire is from the contactor to the run side of the run capacitor or from the contactor to the run connection on the compressor. hence the old slogan reds run when you point a gun at them. the only wire left is the start wire that come from the start capacitor and is usually yellow . hence the old saying blacks are common, reds run, and yellows are always starting something. very ethnic i know but thats how i was taught.now that the wirings correct check to see volts through contactor are correct and if one side of contactor is not feeding. if volts good then check capacitors with a cap checker. if all else looks good kill power and inspect compressor terminals at compressor. if burned off consider a termilock kit good luck..

Double check that the new contactor has the same electrical ratings on it. My guess is that the coil should be 24v while the relay should be able to carry the same amperage at 220v.

First shut off the breaker and disconnect switch for the furnace and outdoor condenser and call a licensed HVAC contractor:)

If you are determined to do it yourself, Then read the schematics first. Be aware, if you mis wire the system you may cause more damage than you have now. Not to mention your personal safety is at risk.

I am basing this on the most common style contactor found in my area.

The main relay side should be labeled. (eg. L1,L2-T1, T2). These should match exactly like the old one. L1 and L2 are the incoming power. T1 and T2 are the power leaving the contactor. All the 220v wires should correspond to one of these four terminals either by screwing them down or fitting the spade connectors together.

Usually the 24v wires will plug onto the coil (near the bottom, left and/or right sides of the contactor) silver spade connectors.

(STEP 1.) Leave all Wires Connected to your Old Contactor.
(STEP 2.) Remove the two mounting screws that hold the Old Contactor to the Air Conditioners casing.
(STEP 3.) Now Install the New Contactor to the old contactors existing location using the Same two Screws.
(STEP 4.) Now take Off one wire at a time from your old Contactor and Install each wire one at a time to the proper location on the new Contactor.
