Description
The Carrier HH660103 Rollout Switch Kit is a genuine OEM replacement safety component designed to protect your furnace from dangerous flame rollout conditions. This complete kit includes a 225°F rollout switch and a pilot duty relay, providing everything needed for a proper, code-compliant installation or replacement.
Product Overview
Flame rollout switches are critical safety devices that monitor burner flame behavior. When abnormal flame rollout is detected — caused by heat exchanger blockages, venting issues, or other combustion problems — the rollout switch trips to shut down the burner and prevent potential fire hazards or carbon monoxide exposure. The included pilot duty relay ensures proper integration with the furnace control circuit.
