Heil Quaker ICP 1171325 Rollout Switch the thermocouple likely failed toThe Heil Quaker ICP 1171325 Rollout Switch is a critical safety component designed for furnace flame rollout protection. This SPST (Single Pole Single Throw) safety switch is engineered to interrupt the heating cycle if it detects sustained thermal exposure near the burner assembly, preventing hazardous conditions caused by restricted venting or heat exchanger failure. Operating with high precision thresholds, the ICP 1171325 features a 195 degree F
