What does R5 mean?
The R5 error code on your York furnace indicates that the rollout switch has tripped. This switch is a critical safety device designed to shut down the furnace if it detects flames where they shouldn't be – specifically, outside the normal burner area. This is a serious issue because it means there's a risk of fire or carbon monoxide poisoning. The rollout switch is a small, often red, button located near the burners. When it senses excessive heat from a 'rollout' flame, it opens the circuit, cutting off gas flow to the burners. Ignoring this error can lead to dangerous conditions, so it's important to address it immediately.
