does the furnace ignite?? your system may not have been lighting and has gone into ignition lockout count the codes of the led lights then remove panel led diagnostic codes are listed there.
if led codes indicate no problem verify capacitor is good and that mtr is getting 115 volts.

A code 12 is "Blower on after power-up" Try resetting the furnace with either the Emergency switch or circuit breaker. If it continues, you may need a new control board.

I had the same problem, the motor shaft and bearings were going bad. There was about 3/16" travel on the shaft that the blower attaches to. I replaced the motor myself and it runs nice and quiet. I have had that noise that you describe for over 8 years, but it got real noisy about a week ago. I talked to the maintance department about it where I work and they said the motor bearings were probably going bad. They were right, I took the motor out of the furnace and they took it to a parts store and got me a new one $270.00 for it. It is a special motor due to the fact that the frame mounts bolt directly onto the motor housing. Make sure if you do this job yourself that you take the motor to the parts store so that they can match it up. The guy at the store told our maintance man if it didn't require the bolt holes in the motor housing it would have been $100.00 cheaper.

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.
