Carrier 50HJ401431 Flame Sensor

The Carrier 50HJ401431 is a genuine Carrier replacement flame sensor. The flame sensor sits in the burner flame and uses the flame rectification principle: the flame conducts a tiny current from the sensor rod to ground, and the control reads that microamp signal as proof that the burners have lit. If the signal is missing or too weak, the control shuts off the gas valve and retries or locks out. A sensor rod coated with oxidation or a cracked insulator is a frequent cause of burners that light and then drop out after a few seconds.

Use it to replace a failed 50HJ401431 in Carrier equipment that specifies this part number. UPC 66244144593. Shipping weight 0.5 lb.
