Im trying to wire up a 3phase 480 volt contater with a 120 volt coil contacter didnt come with any drawings not sure how to wire it up using a remote start stop button

If you are trying to wire the coil only you wire it just like a light bulb and the light switch would be for remote operation. The 3phase power in will go to T1,T2,T3 and your load goes to L1,L2,L3. If you are working with a starter and not a contactor the hookup is different. A starter is a contactor with an overload attached to it. A starter hook up is too difficult for me to explain in this format and I would suggest getting someone to do some hands on instruction. Hope this helps, good luck.

My a/c ruud/rheem wont come on by it self noisy relay

did you replace the contactor. if so, you need to verify the control coil voltage. should be a 24v coil. you need to also check to verify you are getting 24v at the contactor coil.

Magnetic switch on outside unit does not activate - when I depress and hold in relay fan and compressor operate and cool house

Hi, this relay is your contactor that you are pushing in to make it run. You are not getting 24 volts to the 2 small wires that terminate on the side of this contactor. These 2 wires are low voltage and are controlled from the thermostat and indoor unit. You either have a faulty thermostat, or you may have blown the fuse on the indoor unit, if yours has one. Remove the panel on the indoor unit to see if you have a circuit board.See if you have a fuse that is just like a automotive plug in fuse that's plugged into the board. See if it is blown. If not, is the indoor unit running, its just the outdoor unit that will not come on? If the indoor unit comes on and runs, but the outdoor unit does not come on, you more then likely have a time delay relay that is mounted on the outdoor unit that is faulty and will not send 24 volts to the delay.It has failed, and that is why it will only start when you push the contacts down on the contactor. Some are a small black square box with 2 to 3 wires on them, and some are a small square circuit board that will have T-1, T-2, and the box type will have like a timer on the face. They can be bypassed, as I have done this many times to get people cooling, but you need to no what wires to remove and terminate to the contactor coil. The large wires going into this contactor you are pushing down, are very high voltage, so I wouldn't recommend doing this, as you will get shocked and this is not solving your problem, but I am glad you have told me what is going on, it has helped very much. If your indoor unit comes on with the thermostat, I am sure the stat is good, but your delay relay has failed not letting the contactor to energize by its self. You would need to find out which 2 wires on this delay relay to move to the contator coil. You would need a meter to check to see which ones to use. You can do this. Turn off the breaker to the complete unit, both indoor and outdoor. The 2- small wires that are coming from inside your house that run along the copper pipes are the 2 you need to use. If you do have a time delay relay, these 2 wires will go into the control area, and wire up to 2 other wires that plug into this relay. What you can do, is take these 2 wires coming from the house, probably red and white, and what you need to do is the contactor that you have been pushing down will have a brown and blue small wires hooked on each lower side of it. This is the 24 volt coil. The 2 wires have 2 female connectors on the ends of them.Leave them plugged into the coil if you have enough to work with, and cut one at a time and take the 2 from the house and hook one to one side and one to the other side, tape them up, and you are done!so, all you are really doing is taking the 2 wires coming outside that start the unit, bypassing the bad time delay and hooking them up right to each side of the contactor coil you are pushing down. Very simple, just take your time, and follow my steps. Let me know how you have done. This will save you lots of $$$$. Now, you are activating the coil like it should be, with out the bad time delay, as you will not need it because your thermostat also has a delay. Please let me know the out come.

My ac is blowing out air but it is not cold and the fan outside is not running

Hello, first thing to check is if you are getting voltage at your outside disconnect, you should get 240 volts, if not check for a tripped breaker or a blown fuse. next check power at the contactor coil you should have 240 on the line side of the contactor. If that checks out good check for 24 volts at the side terminals of the contator coil, if you have 24 volts at the coil does not energize than you have a bad contactor coil. If there is no 24 volts at the contactor coil side terminals than either there is a problem with the thermostat or low voltage wiring. and finally if that all checks out good than your capacitor must be replaced.

I need the part number for the contactor that feeds the compressor

Usually when you replace the contactor, you do it by the number of poles and the amp rating on the contactor and the coil voltage,
for instance most AC contactors are 2 pole, 25 to 50 amp and 24 volt coil.
If you look on the contactor you have it should have the amp rating on the side and coil voltage is usually there also and you can look at the contactor to see how many poles.

I need a coil for a split unit intertherm unit I dont know the model but the moble home is a 1998

That's not going to cut it. You can't just stick a coil on a system. You will need model # of furnace and most importantly the model # of the outdoor unit in order to find a coil that is an appropriate match; otherwise, you will probably end up shooting yourself in the foot and spending alot more in the long run to fix mistakes. I recomend contating a local professional to help you.
