Description
Overview
The International Comfort Products 34335002 is an OEM auto-reset high-limit switch engineered to protect furnaces from dangerous overheating conditions. When supply air temperatures reach the upper threshold, this limit switch interrupts the burner circuit and automatically resets once temperatures return to a safe operating range — providing reliable, hands-free protection without requiring a manual reset.
Key Features
- Auto-reset operation — automatically restores normal furnace function once temperatures drop to a safe level
- 220–240°F trip temperature range for precise high-limit protection
- Direct OEM replacement for compatible International Comfort Products furnace models
- Interrupts burner operation to prevent heat exchanger damage and potential fire hazards
- Designed for dependable, long-service-life performance in residential and light commercial heating applications
Application
This limit switch is a critical safety component in ICP furnaces. It monitors supply air temperature and shuts down the burner if airflow is restricted or the heat exchanger overheats. The auto-reset feature ensures the furnace resumes normal operation once safe temperatures are restored, minimizing downtime and service calls.
