- !Furnace blower running but blowing cold air
- !Furnace failing to turn on or shutting off immediately after starting
- !Frequent cycling (turning on and off rapidly)
- !Yellow or flickering flame instead of a steady blue flame (carbon monoxide hazard)
Potential Causes
The most frequent underlying reasons behind this issue:

- ?Defective gas valve or inducer motor
💡 Expert Maintenance Tip
