  If the motor of your Munters Heater runs but fails to ignite, consider these potential causes: * **Fuel Issues:** Check if the fuel tank is empty, or if the fuel is dirty or incorrect. Remove any wrong or dirty fuel. * **Fuel Filter:** A clogged fuel filter can prevent ignition. Clean or replace the fuel filter. * **Air Leaks:** Air leaks in the oil line can disrupt the process. Check the pipes, tighten connections, and replace if necessary. * **Burner Nozzle:** A clogged burner nozzle can also be the culprit. Clean the nozzle by blowing compressed air, and replace it if needed. * **Fuel Viscosity:** Low temperatures can increase fuel viscosity. Mix the oil with 10-20% kerosene to resolve this.
