R68GF0004 Mortex FLAME SENSOR

Mortex R68GF0004 OEM Furnace Flame Sensor The R68GF0004 is the factory‑specified flame sensor used in Mortex mobile‑home and modular‑home gas furnaces. This flame‑proving rod detects burner flame presence and signals the control board to keep the gas valve open. When the sensor becomes dirty, weak, or fails to read flame, the furnace will short‑cycle or lock out. The R68GF0004 restores reliable ignition and safe burner operation with an exact OEM fit.
