The Rinnai Over Heat Switch (805000164) is a genuine OEM safety component for i-Series Plus combination boilers. This high-limit safety switch monitors heat exchanger temperature and shuts down the burner if temperatures exceed safe operating limits, preventing heat exchanger damage or catastrophic system failure. If the overheat switch trips repeatedly or fails to reset, it indicates either an underlying fault condition or a failed switch. Always replace with this OEM part to restore proper overheat protection.
