What to do if the fan comes on but the flame does not light on my Master BV 110 E Heater?

If the fan of your Master Heater comes on, but the flame doesn't light or stay lit, there are several possible causes. First, the ignitor might not be working; check the connections of the ignition cables, the position and cleanliness of the electrodes, and consider replacing the ignition transformer. Second, the flame cut out mechanism could be faulty and need replacement. Third, the photoelectric cell may not be functioning correctly; try cleaning or replacing it. Fourth, the fuel might not be reaching the burner adequately; ensure the pump is connected to the motor, check for air in the fuel circuit, and clean or replace the nozzle. Finally, the electric valve might be malfunctioning; check its electrical connection and the TS thermostat, and clean or replace the valve if necessary.
