The International Comfort Products 34335004 is an automatic limit switch designed for residential and light commercial HVAC applications. This safety control is factory-calibrated to operate within the 90-110°F temperature range, providing critical overheat protection for furnace and heating systems.

Key Features:

• Automatic reset limit switch with 90-110°F operating range
• Designed as a direct OEM replacement for International Comfort Products furnaces
• Safety control that prevents furnace overheating by shutting off burner when temperature exceeds safe limits
• Automatically resets when temperature returns to normal operating range

This limit switch is an essential safety component that monitors the temperature of the heat exchanger. When the temperature rises above the preset limit, the switch opens to shut down the burner, preventing potential damage to the furnace. Once the temperature drops back into the acceptable range, the switch automatically closes to resume normal operation.
