Most electrical problems in air conditioning systems are in the compressors and their relays or motor overload switches. Watch out : live high voltage may be present at a capacitor, capable of giving a tremendous electrical shock even after electrical power has been disconnected at the equipment.

Never work on live electrical equipment. A fractional horsepower electrical motor should show different electrical resistance between the three terminals Start, Run, and Common as we illustrate just below. Electric Motor run speed side note : Incidentally while most electric motors are marked with a data tag indicating the motor run speed in RPMs it's worth noting that the number of run coils is what determines the run speed of the motor.

Two-coils marks a motor that runs at rpm rpm "nominal" , while 4 coils marks a rpm motor. Quoting from Part No. SPP-5, a relay and hard start capacitor sold by that company:. Connect the two wires from the SPP-5 in parallel with the [existing, already installed] run capacitor one wire each side without removing any original wires.

Use special "piggy back" terminal of the SPP-5 if all the run capacitor terminals are being used. Here are some sample capacitor installation instructions for adding a motor starter capacitor to an air conditioning compressor motor - taken from the product package for a relay and start capacitor intended for use on a refrigerator or freezer.

Similar starter capacitors are available for air conditioning compressors. However there are some other capacitor mounting considerations that can affect capacitor life: basically you want to minimize the capacitor's exposure to vibration and heat. As Afacp points out, It is advisable to make an experimental measurement of the temperature reached by the capacitor under the working conditions in the final application and after the thermal equilibrium has been achieved.

When testing a compressor, one must discharge the capacitor first! It'll otherwise have enough power stored on it to be at least very painful. Author and others have been zapped! Some systems will automatically discharge the capacitor, but shorting its leads [to ground] with a screwdriver after verifying that the power's off is a safe way to ensure that you won't get shocked.

Motor starting capacitors can hold a charge for days! If oil has leaked out of a capacitor : Don't touch any oil that leaked out: old capacitors may contain PCB oils, an extremely carcinogenic cancer causing material which require special disposal.

Once the capacitor has been discharged as described just above , then it can be tested with a multi meter. Either use the meter's built in capacitor test function, or use this trick: Charge the capacitor by using the sense current the meter puts out when set to ohms. Disconnect the test leads, and switch over to volts. Then, reconnect the test leads. A voltage reading should be observed, approaching zero.

If the capacitor doesn't hold a charge , or the resistance reading never approaches infinity , it probably needs replacement. Also, the capacitor may be defective if the compressor hums but does not start.

Visual inspection may reveal it to be bulged, or have a blown out safety plug. I'm replacing my run capacitor in my air handler. I forgot to mark the wires I took off. I have 4 wires. A blue, a black, a yellow, and a brown. Brown , and yellow come from the motor. Red, and black go to a control box. What goes where?

Watch out : touching live voltage can kill you. Turn power off and discharge any capacitors before touching anything. A capacitor can store a charge that can hurt you or worse even after power has been turned off.

The tech will typically use an insulated screwdriver to short the F or H terminals to the COM terminal to discharge the cap. While there are common capacitor wiring color conventions that I will cite below, the actually-correct wire colour match to fan motor terminals, wires, and capacitor terminals may vary by motor brand, age, model and application.

But there are steps that can help sort out which wires go where. Next time, remember to tag each wire with an ID and write down its connections before removing wires from their connections on electrical equipment. Watch out : It's safest to take a look at the wiring diagram on the equipment itself - you can follow them to the marked-terminals on your start or run capacitor.

There are also some simple VOM tests that can help identify motor terminals. You should see a wiring diagram glued to the inside of the air handler cabinet or to the inside of the blower compartment door. Now with all that scary arm waving done:.

Those who wish to remain anonymous can also do so. Blower fan motors and other fan motors may have what look like extra wires, not all of which may be in use, depending on the fan speeds required. Power from fan relay to fan motor will typically connect to the T2 terminal on the Contactor relay.

Fan motor direction reverse to counterclockwise if grounded - connect purple to yellow to reverse. Howard St. At left is a simple two-terminal run capacitor.

Katen Generally the capacitor terminals are not polarized and either wire goes on either terminal. Hi I am changing my capacitor Cbb60 6uf flying lead in my pool pump the leads are yellow and blue but new capacitor leads are brown and blue.

JB Thanks for the interesting question, but I just don't know. Tell us the brand and model of your compressor and pressure washer and we can look for the service and maintenance manual that ought to answer the question. Perhaps it's a pressure adjustment. Thanks John. Thank you for the helpful question, Shivkumar. In this case the 3 uf capacitor in your photo is not polarized, so you would arbitrarily connect one black wire to the COM terminal and the other to the power source of the device.

How do I connect. Old defective one has one red one black. If you're converting to using separate start and run capacitors then you will simply use that original COM wire to feed separate Start previously the S wire and Run previously the R wire capacitors.

Replacing a compressor and old Inuit had a run cap with three connections, new compressor uses a start relay, start cap and run cap so the wiring will be different now. Anon Tale a close look at the capacitor wiring terminals to see the letters marking the identity or function of each. I got a 2,2 kw single fased motor that's been messed with the wires and caps. Black blue white red and orange.

NO ground terminal means you certainly can't connect the cap to ground. I'd double check the wiring diagram on the Heil AC unit itself. Replacing year old run capacitor on heil air conditioner. Old capacitor had a third prong for ground. New capacitor does not. How do I connect ground on new capacitor, or do I? Im looking for the wireing of both sart and dual capacitor Diagram. Can you guys help with this,I will really appreciated very much also if you have any videos that I can watch doing so will be really appreciated.

When a motor will run when given a starting spin that's a good tip-off that probably the starter cap is bad. I have a Rheem blower motor that just hums, won't start.

I can't find a start cap. Try the search box just below, or if you prefer, post a question or comment in the Comments box below and we will respond promptly.

Apologies for the delay. Voltage sensing technology that monitors for motor start current sensing devices require internal fuse protection.

A 2-wire connection that simplifies installation 3. A secondary timing circuit that ensures that the capacitor is not permanently left in the start winding circuit 4. A fully electronic device - minimizing the limitations of mechanical devices and secondary fusing associated with triac devices 5.

A start device matched with an appropriately sized capacitor to cover the range of compressors for the intended application one size does not fit all. The use of compressor start devices results from a need to ensure that a compressor usually air conditioning will start under voltage conditions that are less than ideal.

As discussed, several options exist in the market to address compressor start concerns. Start devices exist in many forms for specific applications. SUPCO provides a full range of products in all relevant technologies to effectively match the proper start device to the application.

Care should be taken to utilize a device that meets the requirements of the job. Extra caution should be observed when employing the "one-size-fits-all" and "a bigger capacitor is better" approach to applying a start device.

Consult SUPCO, a manufacturer with a complete product range, to ensure the greatest success in the start device application.
