Not at sister house to try it, The wire that connect to th-w on control module comes from bottom of high limit 24 v side
HVAC Technician: HVAC Guru, HVAC TECH replied 7 months ago

The TH-W wire should be to the thermostat, like this diagram....CLICK HERE, if you jumper 24V to TH-W and it sparks the controller is fine you have a thermostat issue.

All I ask is please use the....FINISH BY RATING link at the top your page to select a 5 STAR RATING before leaving today....this is important for my status on the site plus without a rating I will receive ZERO credit(NO PAY) from the site for assisting you. Also rating now does not close the question out and you can come back anytime for FREE right here to me......Happy Holidays!
