What to do if my Airrex AH-300 Heater stops immediately after ignition?
- HHolly WrightJul 28, 2025
If your Airrex Heater stops immediately after ignition, check if the "Lack of Fuel" light is on and fill up the fuel if needed. Verify that you are using either Diesel or kerosene and drain/replace the fuel if there are any impurities or other types of fuel. Ensure the flame sensor is correctly located. Finally, remove any air in the electric pump if there's noise.
