[ARCHIVED THREAD] - A/C problems

Starting last night my A/C (6 year old Ruud) has two problems:

- the blower will not shut off unless I cut power at the breaker.
- the compressor never kicks on so it only blows warm air.

Is there anything I can troubleshhot before calling in a pro?

I am assuming gas furnace with and air conditioner.

If both problems happened at the same time my guesses would be:

1) Thermostat batteries dead.
2) Control board in furnace broken.
3) Thermostat broken.

Do you have a multimeter?
