    if you are replacing a contactor the best way to do it is to replace wire for wire. if you have already removed the old one you will have a lot of trouble unless you can read schematics. but here are some tips: install incoming power on the L1 L2 sides. Give me a more detaIled question and i can walk you through it

Sorry but I could not find a picture of a Fasco h140a but L's are connected to line (supply) voltage and T's are connected to load (motor). C's are connected to your control voltage, usually the smaller sized wire.

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.

AIR CONDITIONER WIRES, WHERE DOES THE RED, GREEN AND WHITE GO


Hello, you fried the control board or fuse in the inside unit. Usually the wires will attach to the side terminals on the contactor coil, this is part of the contactor is 24 volts, L1 and T1 are high voltage terminals.

Wiring diagram question power from house goes to the 2 top post and ac to the bottom post


assuming you are talking about the 'contactor' you are correct - but be sure the 'top' 2 posts are labeled L1 and L2.
Bottom posts should be labeled T1 and T2
L = Line in
T = load out (compressor/fan motor)

I bought a new universal ac contactor relay to replaced the o.e.m. the new has l1 l2 t1 t2 . the old relay don't say l1 l2 t1 t2 or any indicatio.


The contactor should look alike. Just make sure the same wires are on the same side as the old contactor. Don't worry so much of the l1/t1 and l2/t2

I bought a replacement Dayton electric condenser fan motor. The original GE had 3 wires. L1 L2 & the fan capacitor wire. The Dayton replacement model 4MB21 has 4 wires, L1 L2 and 2 capacitor wires tan...


The tan/white wire can be insulated/capped and not used. Use and ohmmeter to take a resistance reading between the tan/white wire and L1 & L2. There will be no resistance between the tan/white wire and one of the others. This will be the common wire. Connect it to one side of the contactor. Connect the tan wire to the fan terminal on the contactor and the other wire to the common terminal on the capacitor (that is if you have a 3 terminal capacitor, if you have a 2 terminal capacitor connect tan to one side and the other wire to the other). Then connect the other side of the contactor to the common terminal on the capacitor (on a 2 terminal capacitor connect the contactor to the side that doesn't have the tan wire on it).

I NEED TO RECONECT WIRES TO CONTACTER RELAY ON


Power leads L1 and L2 to top terminals of contactor.
Compressor leads T1 and T2 to bottom terminals of contactor
Side terminals get the low voltage leads from transformer.

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.

I would replace them to the exact terminals that they used to be on. Technically speaking L1 and L2 stand for Line one and Line two. This would be the incoming power from the breaker or disconnect switch. T1 and T2 are the power leaving the contactor relay.

Replace contactor


On single phase your incoming power lines go to L-1 & L-2, the lines to the compressor go to T-1 & T-2. With A/C current it does not matter which one goes to which side as long as the line goes to the L side and the compressor power lines go to the T side. As long as the coil voltage is correct any contactor will replace the original.
