💡 What makes a furnace rollout safety switch trip during normal burning cycles?
- Dirty filters or blocked return vents restrict hot gas flow causing internal temps to spike past factory rated limits fast
- Faulty igniters or cracked baffles let raw flames wander out of sight triggering the thermal cutoff mechanism abruptly
- Slapping in fresh sensor units brings back tight voltage tracking and handy temperature management so your home stays cozy without constant breaker flipping
- Regular duct cleaning and swapping out dated wiring pairs keeps the heat exchange loop smooth and stops useless downtime in dead of winter
