Description
Overview
The International Comfort Products 34335000 is an automatic reset high-limit switch engineered to protect furnace heat exchangers and related components from dangerous overtemperature conditions. Designed as a direct OEM replacement for compatible ICP heating systems, this limit switch provides reliable thermal protection and automatic recovery once safe operating temperatures are restored.
How It Works
The limit switch monitors supply air or heat exchanger temperatures during furnace operation. When temperatures reach the upper trip threshold of 160°F, the switch opens the control circuit, shutting down the burner to prevent damage or unsafe conditions. Once temperatures fall back to the reset point of 140°F, the switch automatically resets and restores normal furnace operation — no manual intervention required.
