Question about Heating & Cooling
Can you tell me where I can get the wiring diagram/schematic for my Ruud heat pump, model number UHQA1210BNS. Had a water problem that caused the diagram on the inside panel for the electrical connections to become difficult to read. Tried gently cleaning diagram to remove the rust/dirt. It helped a little until part of the paper started to come off.
My immediate conern is to learn what the orange wire, coming out of the Ruud air handler (the unit inside the house), connects to. Either to the thermostat and/or the control cable going to the outside unit.
This is a 2nd posting. My 1st posting was a little unclear after I re-read it.
Thanks in advance,
We are trying to install a goodman heat pump with a rheem air handler, the orange wire is hook up and the unit is still staying in the heat mood. does anyone have a wiring diagram for the air handler, their is some white wires in the air handler one with a purple strip and one with a black strip we need help

The orange wire coming out of the outside unit is for the reversing valve( controls the heat and cool mode of the ac) If its unhooked, it will be either in the ac mode all the time or the heating mode all the time depending on the style of the reversing valve. The orange wire goes to the (O terminal) inside the outside unit.
There is also another orange wire that goes from the air handler to the thermostat. One orange for the thermostat, and another to the condenser( out side unit)

I'm a Certified HVAC Technician and have been working in this industry since 1996. I simply went too www.google.com and typed in RUUD HEAT PUMP WIRING DIAGRAM, and found the following website URL where you can view and download and print your own PDF copy:
But, for your information, in MOST cases, standard COLOR Coded WIRING for HEAT PUMP applications shows the ORANGE wire gets landed onto the "O" Terminal on the Heat Pump Thermostat, at the AIR HANDLER both ORANGE WIRES simply get twisted together and capped off with a WIRE NUT, and the ORANGE WIRE on the OUTDOOR UNIT also gets twisted together with the ORANGE WIRE coming down from the AIR HANDLER UNIT and capped off with a WIRE NUT. Therefore, O = Orange Wire = Reversing Valve. Good Luck
