Carrier HH18HA202 Rollout Switch 30067439-890 providing stable liquid flow controlThe Carrier HH18HA202 Rollout Switch is a critical safety component designed for gas fired furnaces and heating systems. Engineered as a manual reset limit switch, this SPST (Single Pole Single Throw) device is calibrated to open the circuit at a fixed 350 degrees F. When excessive heat is detectedtypically indicating a flame rollout condition or heat exchanger breachthe switch interrupts the 24V control circuit to shut down the gas valve immediately.
