SOURCE: Ruud heat pump outside unit trips circuit breaker

Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.

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.

SOURCE: High Pressure cutoff

YOUR OUTDOOR FAN MOTOR SHOULD NEVER SHUT OFF IN THE AC MODE. IT IS SUPPOSED TO SHUT OFF IN THE HEAT MODE WHEN ITS IN DEFROST. IF THE UNIT IS RUNNING IN COOL AND THE OUTSIDE MOTOR QUITS ,THE COMPRESSOR WILL QUIT SOON AFTER. EITHER THE RUN CAPACITOR FOR THE FAN IS BAD OR THE FAN MOTOR ITSELF IS BAD, IF CAP IS GOOD THEN THE MOTOR IS At FAULT. THE OUTDOOR PRESSURE SWITCH CAN ALSO OPEN IF THE INDOOR FAN MOTOR FAILS IN HEAT OR THE FILTER IS PLUM NASTY in heat OR THE INDOOR COIL IS PLUGGED UP in heat.. THE PRESSURE SWITCH USUALLY TRIPS AT 400 TO 425 SO ITS WORKING CORRECTLY. YOU MAY BE CONFUSING THE ISSUE SAYING THAT THE AIR IS HOT AND COLD INSIDE. IT IS COLD WHEN AC IS RUNNING HOT WHEN HEAT PUMP IS RUNNING IN HEAT BUT ESSENTIALLY not cold or hot if compressor isn't running, but a lot of folks describe the lack of cold air as hot when the compressor isnt running. but it basically is warm or house air temp.you test the capacitor with a capacitor tester or take it to motor shop and let them test it. odds are its a 5 , 7.5 or a 10. it should test within 10 % of rated value . ask for a RESCUE brand replacement motor. they are great ,reversable etc.carefully oil and sand the motor shaft and note exactly where the blade was located in relation to the grill so you get it back just the same. usually they wire up black to a leg of 220 power. white to the other leg of 220 power. brown and brown with white stripe to the capacitor.you can also pull whole fan shroud assembly on some units and take whole thing to motor shop and let them test motor cap, replace and all you do is return to unit and connect two power leads,

You may have cottonwood on your compressor. Before you spend any money, do two things. Rinse off your compressor to clear any cottonwood, and check your filters, they may need to be replaced. Hope that helps!

I have a Ruud AC Model UAMBO48JAZ That has started to have a hum when it is running it is cooling and has been checked for freon. Could it be the capacitor?


More than likely, it is the hum of the coil in the contactor. Generally, residential uses 24 volts to energize the coil built into the contactor which pulls in a set of contacts (hence the name contactor) to send 220 volts to power the compressor & condenser fan motor. Contactors are relatively inexpensive... so if the noise bothers you, replace it or have it replaced. Put your mind @ ease, the humming noise will do no damage.

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

The buzzing sound is from the contactor and only means you have low voltage at the unit,Check and make sure you have 240 volts at the unit and post back.
