Carrier HH18HA226 Rollout Switch 321142-301 8 Cv flow coefficient withThe Carrier HH18HA226 Rollout Switch is a critical safety component designed for Carrier, Bryant, and Payne gas furnaces. Engineered to detect flame rollout conditionswhere burner flames escape the heat exchangerthis Single Pole Single Throw (SPST) switch protects the heating unit and surrounding structure from high temperature damage. This specific model triggers an open circuit at 320 degrees F, immediately interrupting the gas valve circuit to stop
