Possible Causes

Blocked vent, Failed pressure switch, Disconnected pressure tubing, Faulty blower proving circuit

Safety: Turn off power and gas. Do not operate with a suspected vent blockage.

1. Check vent termination: Inspect outside vent for obstructions and clear any debris.
2. Inspect pressure tubing: Ensure tubing between blower and pressure switch is intact and not kinked or filled with water.
3. Test pressure switch: With a multimeter, verify the switch closes when the blower runs. Replace if it fails to close.
4. Verify blower operation: Confirm the blower starts and runs smoothly. Replace blower if it fails to start or is noisy and weak.
