I have a Heil HVAC unit that continues to run until the breaker is turned off.

Trouble shooting:

I removed the T-Stat and turned the breaker back on, and after 2 -3 minutes the condenser fan would cycle for about 1 minute and then off. This pattern would repeat it's self until I flipped the breaker off again.

Any ideas what to test/check next?
Thanks
