What are the causes of diesel heater motor failure?

[HarrisonRose]

Common failures of diesel heater motors include emitting smoke without combustion, and flames extinguishing easily after ignition. Emitting smoke without combustion: This situation is caused by poor ventilation. If ventilation is inadequate, leading to an oxygen-deficient internal environment, the compressed fuel cannot combust completely, resulting in only smoke emission. The solution is to clear the ventilation system of the diesel heater or reduce the fuel supply to create a better ventilated environment. Flames extinguishing easily after ignition: This issue is generally caused by poor liquid circulation in the water pipes or air in the fuel lines. Check if the water pipes are kinked to ensure proper liquid circulation and prevent air from entering the fuel lines.
