If no air is reaching the burner, it cannot combust and may enter lockout mode. This occurs most often because of a blocked or covered air vent. Snow and debris may be cutting off your furnace oxygen supply. Dirty air filters may also be responsible. Solve this issue by cleaning debris and replacing filters.faults. During a fault, excessive current—called fault current— flows through the electrical system often resulting in a failure of one section of that system by causing a tripped circuit breaker or a blown fuse. A fault current limiter (FCL) limits the amount of current flow-ing through the system and allows for the continual, uninterrupted33 Limit circuit fault.
