Relay could be problem. See if thermostat makes relay click. If it does and you hear compressor try to run when it closes, everything is good in control circiut. Then check Start and Run capacitors. May be just one capacitor with 3 terminals on it. If there is any oil leaking out of it or if its swelled, Thats the problem, Replace it with same size capacitor. Mark wires before you remove them. If you hear relay try to close but no sound from the compressor, Check the High Pressure switch. They usually have a red reset button. If its tripped, Could be the condensor fan motor or grass and **** blocking air flow on condensor coil. If you hear no compressor noise and high pressure switch is not tripped but relay acts like its working, Replace relay. DANGER!!! High Voltage!!! Make sure that all power is off of both units before touching wires. Hope this helps. Let me know. Am on yahoo IM as kstfas if you yahoo.

The breaker wont reset to the compressor. I had the cap checked it's ok. also I checked the wire harness, it's ok. please advise.


If you are trying to reset the breaker and it trips as soon as you go to on, you have a dead short or a bad breaker. If you can hear the compressor, if it just hums or vibrates most likely it has an internal short and needs to be replaced.

Sounds like your fan manager/Fan relay has malfunctioned.
In some cases it could possibly be the program on a Thermostat not allowing the fan to turn on, But in my experiences sounds like a bad fan relay.
Hope this helps.

Take the front panel off the air handler and look for a heat element. You should notice controls and relays with larger wiring to it. It may not have any heat but you can add it.

I have a Ruud air-conditioner/heat pump and it blows 5 amp fuse.


It sounds like the thermostat wire going to the condenser is ground, It either got pulled loose and is touching the housing or as in most cases the wire got cut or was chewed by an animal. You need to turn electric off to both devices and physically inspect the thermostat wire going from the air handler to the outside unit, also inspect where they connect inside the unit. When you find the break, cut and strip each individual wire and securely wire nut each conducter red to red white to white and so on. There you go all fixed. That's when I give you the bill for $75...except this time you write that check to yourself. Good Luck

The outside fan motor (OFM) will not turn off.


it sounds like your fan connector is on the same side of the contactor where your high voltage enters you should have 3 wires 1 wire for each pole of the contactor and 1 wire off the capacitor does the compressor run all the time too? try turning the power switch off on your indoor air handler / gas furnace if the power goes off the fan goes off then it could be low voltage wiring

It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.

Ruud air handlers


Check the name plate amperage on the air handler. The air handler only has the blower motor as its main current draw. #12 wire is rated for 20 Amp service. If the amp draw by the unit supplied by the disconnect is under 15 amps it should be fine (but) once again check the name plate for ampacity rating.
