Description
This replacement limit switch is a genuine OEM component designed for CARRIER HH18HA495 furnace systems and compatible models. It functions as a critical safety device, commonly referred to as a flame rollout switch or high-limit switch, that protects HVAC furnaces from overheating and flame rollout conditions. The switch is calibrated to open at 350 Degrees F, automatically interrupting the heating cycle to prevent equipment damage, fire hazards, and potential property loss. The unit features manual reset operation, requiring qualified technician intervention after activation. This design ensures that underlying issues causing the overheat condition are properly inspected and corrected before system restart, promoting safer equipment operation and preventing recurrent failures. The switch employs a Single Pole Single Throw (SPST) electrical configuration for straightforward installation and reliable performance in standard furnace applications. Constructed with a teardrop-shaped mounting design, this limit switch provides a secure, stable fit within furnace cabinets and housings. The robust construction and precise temperature sensitivity make it suitable for demanding commercial and residential HVAC environments where consistent safety performance is essential. This replacement component meets OEM specifications and is ideal for service technicians, HVAC contractors, and facility managers maintaining CARRIER heating systems and equivalent equipment requiring reliable overheat protection.
