The 55 terminal is marked "herm" it goes to the start winding of the compressor. The 5 terminal is marked "fan" it goes to a wire from the fan motor. The common terminal goes to one side of the power line...The side that is NOT going directly to the compressor.

The condenser unit will not kick on...it is a concord unit,10=12 years old,13 seer,3 ton. The air handler works fine. I thought it was the capacitor. The old one was bad,I verified that with multimeter....


It could be a low refrigerant cut-out (switch), grounded or shorted motor windings, open internal winding overload protector (check at the common winding), a broken conductor, or no power at condensing unit from blown fuses or open/tripped breaker.

Intertherm Air Conditioner S3BA-042KA compressor and fan not working (has power)


It sounds like that unit is connected to a "power saving load controller" device from the power company. The power company can turn your unit on & off with a radio signal. If you manually activated contactor and unit ran. I would bet that the power company's device or the wiring connecting it is where the problem lies. Call the power company and have them check their device. If they tell you that the device has been tested remotely and is working fine. Explain to them that you can activate your unit manually and it works fine. They should not charge you to come out. Those "load controller devices" have a pretty good longevity record.

Electrolux split AC 1.5 ton inside fan working.But out side compressor fan stops after two or three rotations.


The 2 most common issues are a freon leak or the outside unit fan start capacitor goes out. It's more likely a capacitor issue. They fail regularly, especially when it's hot out. I had a fan capacitor go out on one of my 3 units last year and it cost close to $300 for an AC company to come out and fix it. I watched them fix it and it's something that you can do yourself if you know what you're doing and are careful to hook it up right. I have three AC units and another capacitor went out this year and I found a kit with detailed instructions with pictures and phone support at hvacrepairkits.com. It saved me over $200 on the capacitor replacement.

The compressor fan does not spin and sometimes it spins backwards


Your capacitor is definitely the culprit here.
It should be a dual capacitor. Meaning it has 3 terminals on one capacitor. "C" "H" and "F" would be the markings for power in,"C" out to fan "F" and out to compressor "H".
It also has a mfd(microfarad) value on the capacitor as well as a VAC rating of 370 or 440 volts ac. A 440 VAC can be used in place of a 370vac.
The other specs may be something like 40/5 or 35/5 or 40/7.5 etc.
The capacitor replacement should be exact as far as the microfarad rating is concerned.( eg. 40+5).
The money requested through various sites is just that....various. These dual caps may sell around 30-50 dollars for a quality capacitor. If you wish to spend the $118 I will sell you all as many as you would like.

Voltage 1phase or 3 phase 240 volts BTUs M# 585epo36o75


Looking at the model number, it appears to be a 3 ton. (36,000 btu) Most all residential units are single phase and most all commercial are 3 phase. One way to tell, look to see if the compressor has a capacitor. 3 phase never use capacitors on the compressors as they are not needed. Some residential units have a "Dual" capacitor. That is, it has 3 terminals, 1 common, 1 for condenser fan motor, and 1 for the compressor. Also, this info should be printed on the unit's lable.
Good Luck and hope this helps.

Home unit 3 ton won't run


The small capacitor is for the fan motor the other for thecompresor .You can try conecting a booster (or hot start) in paralel to the comp.capacitor .If this doesnt work you have to replace the compresor.
