SOURCE: ruud heat pump
If I understand what you are saying, when your stat calls for cool the unit blows heat and when in heat mode it blows cool. Is this correct?
The problem is on a Ruud unit it does not use an "O" terminal it uses a "B" terminal (Reversing valve energized for heat) where all others use the "O" energized for cool mode.
As for the contactor not closing you need to determin if there is 24 volts between "Y" and "C" at the unit, if not then there is an issue somewhere up the line interupting the voltage, if there is then the fault lies at the unit, defrost boaard or pressure switch. call me and we can diagnose over the phone, this is what I do.

SOURCE: I have a new Rheem
if this is indeed a heat pump you rthermostat should also have a emergency heat setting does it work on that setting... a heat pump on heat wuns the outside unit and has a recersing valve that changes the refigerant flow ..is the outside runnignduring heat mode... if you turn the thermostat in emergency heat the outside should shut down and indoor heat should come on...of this is not happening you have a wiring issue if both are not working... braeburn thermostats usually have behind the cover dip switches... i am not exactly sure what model this is but if indeed a heat pump the thermostat should have a r,w2,y,e,g,c,o,and b terminal... rheem wiring should be as follows
red to r white to w2 , g=green , yellow to y terminal there should be a wire hooked to the b terminal usually brown sometimes orange on the b terminal that is your reversing valve terminal.
you are going to have to make sure the thermostat is configured to energize the b termianl and will have to go into the installer setup to do this...hopefully you still have the paper work on thermostat... most heat pumps use the o terminal for reversing valve but rheem uses the b terminal
hope this helps out some repost with anymore probs...also make sure the switches are set to electric or gas whatever you have heat pump or not etc. inside thermostat
