Description
The International Comfort Products B04273 is an 8″ Fan/Limit Switch Kit designed as a direct OEM replacement for compatible ICP heating systems. This essential furnace control component performs two critical functions: it regulates the blower fan’s on/off operation based on heat exchanger temperature and provides high-limit protection to shut down the burner if the system overheats — safeguarding both equipment and occupants.
Key Features
- OEM replacement fan/limit switch kit from International Comfort Products
- 8″ insertion depth for proper heat exchanger sensing
- Dual-function design: controls blower fan activation and high-limit safety cutout
- Protects furnace from overheating by shutting off burners at preset high-limit temperature
- Activates and deactivates the circulating blower fan at appropriate temperature thresholds
- Designed for direct fit into compatible ICP furnace models
Why Replace Your Fan/Limit Switch?
A faulty fan/limit switch can cause a furnace to short-cycle, fail to circulate warm air, or run without adequate safety protection. Replacing it with the correct OEM part — the ICP B04273 — restores proper blower sequencing and ensures the high-limit safety circuit is fully operational, keeping your system running efficiently and safely.
