I need capacitor


Turn power off at disconnect box. Should be outside by the a/c condensor. is this a run capacitor or start capacitor? if it has two brown wires it is a run capacitor if it has 3 wires such as red, black and brown it is a start capacitor.
Even with the power off the old capacitor may hold a charge. To discharge Take a tool with insulated handles such as a screwdriver and touch all post at the same time. Remove the two or three wires usually both brown one may have a white stripe or three wires make sure to make note on what terminals each color came off of on a start capacitor. On a run capacitor only two wires do not need to mark as they can be on either post . Take this to a HVAC parts supplier in your area. The information on the side of the capacitor will insure you get a proper replacement. have them test the capacitor they should do this for free to insure the capacitor is bad. Reinstall secure wires and turn power supply back on.

Wiring up a compressor + start kit



Wiring up a compressor
If there is an identifying mark on one side of the capacitor such as a Dash, Red paint or arrow pointing one direction that will be the run side of the capacitor, if no marks you can use either side for start or run.
If you have three terminals on the capacitor you have a dual capacitor, (C = RUN compressor and fan) (HERM = compressor start) and (FAN is fan start wire).
The Start wire goes to one side of the run capacitor it will be the only wire on that side of the capacitor.
The Run wire goes to the terminal side (T2) of the contactor, it will have another
wire from that terminal to the run capacitor which is the opposite side of the start wire.
The Common wire will go to the other side of the contactor (T1).
Start Kit
Start from the capacitor to terminal #1 on start relay There should be another wire from
here to start on the compressor.
Common from contactor (T1) to terminal #5 on start relay. There should be a wire from this terminal to the Common terminal on the compressor.(there will not be a capacitor in this circuit)
Run from the other side of the contactor (T2) to the start capacitor and from the other
Side of the start capacitor to terminal #2 on the start relay. There should also be a wire from this
Terminal to Run on the compressor.

If you're troubleshooting HVAC electrical problems

230 volt single phase ac
The Common wire or circuit on an A/C or heat pump never has a run capacitor in that line.
The Run wire always has the run capacitor in that line or circuit.

115 volt ac
The Run or Hot wire has the run capacitor and the neutral wire does not.

So if you are tracing wires out in a circuit, if there's a run capacitor, it's the Run wire or Run circuit.
The Start wire always goes to the opposite side of the run capacitor than the Run wire and it is the only wire on that side of the capacitor.
The Run wire goes to the run capacitor, then goes to contactor, compressor, start capacitor or fan, so there's usually two wires on the Run side of the capacitor.

Do no what wires go where on the capacitor for our carrier a/c unit


Some capacitor start motors have two brown leads (one with white stripe) that go to capacitor. Others wire into the start winding, if that is the case follow wiring diagram on the motor. Also if this is in an A/C unit follow the wiring diagram in the unit (usually on inside of cover)

How do I wire a new condensor fan motor to the new capacitor? The old capacitor is longer and it has 3 terminals. the new capacitor is much smaller and oval. It has 2 terminals. the fan motor has 3 wires,...


Before attempting any of these recommendations, First disconnect all the power sources and check your wiring diagrams on the motor and condensing unit.
On the old capacitor if you look on the top near each of the three terminals. Are they marked, fan - C - herm? If they are that is a dual capacitor and that needs to stay because that is also your compressor capacitor.
The Red wire from the conductor is Run and it's connected to C on the old capacitor.
Follow the Yellow wire and see if it goes to the S or start terminal on the compressor, if it does then that is the Start wire for your compressor and it connects to herm on the capacitor.
For the fan motor a lot of times the wiring connections are printed on the motor label.
Check the label, Purple should be run and connect to C on the old capacitor.
Black should be Common and it connects to the opposite side of the contactor as the Red wire. If the Red wire connects to T1 then the Black wire connects to T2.
The Brown wire shoud be the start wire on the fan motor and it connects to the Fan terminal on the old capacitor.
Now if you want to use the new fan capacitor. Take the Purple wire from the motor and look for any marks (red paint or a dash) on or beside the terminals on the new capacitor. If there is an identifying mark then connect the Purple wire to that terminal, if no marks you can connect it to either terminal. Then you need a jumper wire from C on the old capacitor to the purple side of the new capacitor. Then take the brown wire and connect it to opposite terminal of the new capacitor.

A Tip to Remember when Electrical troubleshooting


If you're troubleshooting HVAC electrical problems

230 volt single phase ac
The Common wire or circuit on an A/C or heat pump never has a run capacitor in that line.
The Run wire always has the run capacitor in that line or circuit.

115 volt ac
The Run or Hot wire has the run capacitor and the neutral wire does not.

So if you are tracing wires out in a circuit, if there's a run capacitor, it's the Run wire or Run circuit.
The Start wire always goes to the opposite side of the run capacitor than the Run wire and it is the only wire on that side of the capacitor.
The Run wire goes to the run capacitor, then goes to contactor, compressor, start capacitor or fan, so there's usually two wires on the Run side of the capacitor.

P291-3554RS dual cap is the Carrier part that is called for.


Are you talking about a start capacitor or a run capacitor?
Usually a dual capacitor is a metal can type capacitor with 3 terminals.
C - which is run for compressor and fan.
Herm - is start for the compressor.
Fan - is start for fan.
A start capacitor is a black plastic capacitor
It is in series in the run wire to the potential relay, one side goes to run on the run capacitor and the other side goes to #1 on start or potential relay.

Where do the wires from the compressure go to on main base


Wiring up a compressor
The Start wire goes to one side of the run capacitor it will be the only wire on that side of the capacitor.
The Run wire goes to the terminal side (T1 or T2) of the contactor, it will have another
wire from that terminal to the run capacitor which is the opposite side of the start wire.
The Common wire will go to the other side of the contactor (T1 or T2).
Start Kit
Start from the capacitor to terminal #1 on start relay There should be another wire from
here to start on the compressor.
Common from contactor ( T1 or T2) to terminal #5 on start relay. There should be a wire from this terminal to the Common terminal on the compressor.(there will not be a capacitor in this circuit)
Run from the other side of the contactor ( T1 or T2) to the start capacitor and from the other
Side of the start capacitor to terminal #2 on the start relay. There should also be a wire from this
Terminal to Run on the compressor.

Must Wire replacement Capacitors


First, main power off and use an insulated screwdriver to touch each terminal on the capacitor to the casing (they can hold a charge) The capacitor has 3 terminal marked C, F, H - 2 The wire from the fan goes to F, the wire from the compressor goes to H and a wire coming from the contactor goes to C. For the start capacitor, if it has 2 wires, it goes to the H and C terminals on the main capacitor. If it has more wires, let me know. Ron

Wiring hard start capacitor in GE refrig


I would go back to person who gave that advice because just the right touch on that capacitor and YOU my friend will be in the hospital. If this is helpful, please post as such. TY
