I have checked the breakers and the outdoor on/off switch. Last year I had an outdoor boiler hooked up to my furnace and thermostat, could this be the problem? How do I fix this? Could it have messed up something in the outdoor unit or is it unrelated? Is there a common problem that I could try and fix first without disconnecting the boiler from my thermostat?

When I turn my a/c on the furnace fan comes on but the outside unit does not turn on what could be my problem anyone can tell me what they think might be the problem.
