If your THERMOBILE Heater starts but doesn't produce a flame, several factors could be at play: * The pellet auger might not be functioning correctly; check and correct it. * The flame sensor could be dirty or defective; inspect it and replace it if necessary. * The exhaust air fan may not be working correctly; check and clean it. * The exhaust opening or flue connection might be in poor condition; ensure the heater is connected to a flue in good condition and correct the connections. * The igniter could be faulty; check and replace it if needed.
