What Does York Error Code 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.
Common Causes of York Code R5
- Blocked or dirty burners causing flame rollout
- Cracked or damaged heat exchanger allowing flames to escape
- Insufficient combustion air supply leading to incomplete combustion
- Failed or misaligned burner assembly
- Faulty rollout switch (less common, but possible)
