To Next PageTo Next PageWhat to do if my ICP N9MSB Furnace has an ignition proving failure?
If the flame isn't detected during the ignition trial, the control system will attempt the ignition sequence three more times before a lockout occurs. Ensure the gas valve is turned on, the manual shut-off valve is open, the green/yellow wire is connected to the furnace sheet metal, and the flame sensor is not grounded. Check these items before proceeding.
