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,

The best place is from rudd the cheep price will leave a bad taste in your mouth long after you replace it with after market parts. And the cost will be double. My experience in buying aftermarket parts almost cost me my business when the parts failed and I had to replace for free. Once you plug in a electrical part you own it. Take my advise don't save money on a aftermarket part unless you want to pay for it's repair twice. How ever if you still want to do this look in the yellow pages in your phone book in your town for any motor re-winder and they can get you one. or look on the net with your zip code for the closest rewinder.

I have a RUUD UPKA-036jaz heatpump. Anytime the thermostat is set to heat, the reversing valve coil is energized. Even if the unit isn't running. Is that normal?


Most heat pump reversing valves energize in cooling. Does it ever "deenergize". If not its stuck, if it does check programming, may be setup to operate that way. Or possibly wired wrong or wired as straight cool. To answer your question, i dont think that is normal.

Does ruud unit model # UPKA 061 JAZ have a reset button


Yes it is a little red button on the back lower part of the heat pump by the lineset. it will most commnly trip in heating mode if the filter is dirty. or in A/C mode if there is an issue with the outdoor fan motor or dirty coils.
