Does it trip the breaker when the safety switch is NOT pressed? I am trying to isolate where to look for the short circuit. Is it before the furnace, or after the furnace. If the breaker trips with the safety switch not depressed, the problem is not the furnace, and could be where power enters the furnace, or further upstream from the furnace.

Does the breaker trip when the safety switch is NOT depressed when the breaker is reset?
Follow the following procedure and tell me what happens -
1) Take the blower panel off, making sure the safety switch is NOT depressed.
2) Reset breaker.
Does the breaker reset?
If yes, the problem is in the furnace wiring after the switch.
If it does not reset, then the problem is somewhere before the safety switch.
Let me know what you find.
