Description
The International Comfort Products 34333002 is an automatic-reset high-limit switch engineered to protect furnaces and heating equipment from dangerous overtemperature conditions. Designed as a direct OEM replacement for compatible International Comfort Products systems, this limit switch provides reliable thermal protection and automatic recovery once safe operating temperatures are restored.
How It Works
This limit switch monitors the air temperature within the furnace heat exchanger or plenum. When temperatures reach the upper threshold of 300°F, the switch opens the circuit — shutting down the burner or blower to prevent equipment damage and potential fire hazards. Once the temperature drops back to the 280°F reset point, the switch automatically resets, restoring normal furnace operation without requiring manual intervention.
Key Features
- Auto-reset operation — no manual reset required after temperature normalizes
- Opens at 300°F to halt operation and prevent overheating damage
- Resets at 280°F for automatic return to normal furnace operation
- Direct OEM replacement for compatible International Comfort Products furnaces
- Provides critical overheat protection for heat exchangers and system components
- SKU: 34333002
Application
This limit switch is intended for use in residential and light commercial furnaces manufactured by International Comfort Products. Always verify compatibility with your specific model before installation. Proper limit switch function is essential for safe furnace operation and should be tested and replaced as part of routine HVAC maintenance.
Why Replace Your Limit Switch?
A faulty or worn limit switch can cause nuisance shutdowns, prevent the furnace from firing, or — more critically — fail to protect the system during an actual overheat event. Replacing with a genuine OEM part like the ICP 34333002 ensures accurate trip and reset temperatures and long-term reliability.
