If your BIEMMEDUE Heater's lamp is on but it's not starting, here's what you can check: * Ensure switch (a) is in the correct position. * Verify that the thermostat connection plug is properly inserted and adjust the thermostat setting if needed. * If it's a gas heater, make sure the gas feed pipe has been bled and check the gas feed pressure, as the gas pressure switch may have tripped.
