    carrier 40aq wont power on, please help

    Thank you in advance for anyone that takes the time to supply helpful information.

    I recently replaced my condenser fan motor. AC was running perfect. It got to the point that it was getting too cold so I tried to turn it off but it wouldn't. I set it to off and then raised the temperature on the thermostat but nothing would turn it off. I finally turned it off from the breaker. A few hours later I tried to turn it back on and nothing happened. I tested the green and red wires from the thermostat and there was no spark. What should I try next?

    Seriously, call a pro. I bet you need two new parts maybe 3. Not huge expense, but if you use a sparkplug as a tester you do more damage.
