is​ there any flashing lights that are happening?

Ask Your Own HVAC Question
Customer reply replied 8 months ago
Led 1 is on led 2 is flashing slow, and both roll out swithes are closed
HVAC Technician: Webb-Guy, HVAC Mechanic replied 8 months ago

have you tried resetting the roll out switches yet? If not lets try that first and we can go from there. This could possibly be a clogged inducer motor or your inducer motor may have gone bad.

Tried reset neither one was triped
HVAC Technician: Webb-Guy, HVAC Mechanic replied 8 months ago

ok so what I need you to check is the hoses to the inducer motor you can try blowing through them by your mouth if your careful or somehow making sure there is nothing clogging those hoses.

HVAC Technician: Webb-Guy, HVAC Mechanic replied 8 months ago

because the only other option is that you have a bad board and I want to rule out what we can before diagnosing that.
