Contactors are just a switch l is the power t is the load (check the coil voltage see that its the same) dan

I have an old air compressor that I have replaced the motor magstart and pressure switch on the motor is a 220 / 240 volt 5 horsepower motor it also has a low pressure oil cutoff switch does anybody have a...


Control: L1-SS-P-O-OL-OL-M-L2 In series, L1 is line 1, SS is start/stop switch, P is pressure switch, O is oil switch, OL is overload contact, M is magnetic coil (solenoid), L2 is line 2.
The voltage of M must be rated for the control voltage, across the line voltage (240V) or of a control transformer voltage, e.g. 240v/24v. A control voltage would be wired across the line, to L1 and L2.
Power: L1-T1-OL-M1, L2-T2-OL-M2. Line one to Line 1 on contactor, T1 on contactor jumpered to OL (overload heater) and out the overload heater terminal M1 to the motor terminal 1. Same for line 2, Line 2 to L2 on contactor, T2 on contactor jumpered to OL (overload heater) and out the heater overload terminal to M2 motor terminal.
The heater overload relays needs to be chosen by the motor full load current, a chart is given with a motor starter on selecting heater size. If no chart is available, go 115% of the motor FLA (full load amps) to select a heater size. E.G. 25 FLA motor at 115% is 28.75a. Sorry, no schematic available now, draw your own from this info. If using 3 phase, add the third line as duplicating one other line1 or line 2

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

Compressor contactor relay struck or relay not activated. Remove L1 and L2 wires and jumper with L1 with T1, L2 with T2 and check now. Be careful. It's only checking. When compressor starts, switch off and replace contactor relay.

How do you tell with a voltmeter if the contactor coil is bad?


Check for 24 volts AC at the coil. If you do not have 24 volts at the coil (with AC turned on at your thermostat), then your problem is not with your contactor, but rather a control problem. If you have 24 volts at the coil, check for 240 volts on the LINE side (commonly marked L1 & L2) of your contactor. If you do not have 240 volts, check for open fuse or tripped or bad circuit breaker. If you have 240 volts, check for 240 volts at the LOAD side of your contactor (Commonly marked T1 & T2). With 24 volts on your coil and 240 volts on the LINE side, you should have 240 volts on the LOAD side. If not, the contactor is not making contact.

You can also perform a continuity test as shown in this video:

How to install 25amp 3 pole relay


There should be 8 screws on the relay L1, L2, L3, T1, T2, T3 and two additional screws either at the top or bottom, or one on each side. The incomming, constant power in from the circuit breaker, should connect to L1, L2 & L3. The power out to the load should connect to T1, T2 & T3. The control wire from the switch or timer you will be using to close the contactor will connect to the remaining two screws. THE MOST IMPORTANT PART IS THAT THE CONTROL VOLTAGE MATCHES THE COIL VOLTAGE OF THE CONTACTOR. They will make 12vac, 12vdc, 24vac, 24vdc, 120v, 240v, 277v, etc. coils for the contactor.
Also keep in mind that when the contactor closes L1 & T1 make contact, L2 & T2, Etc.

CONTACTOR WIRING


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.

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.

Coleman evcon moblehome ac question


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.
