Mr. Heater MH9B Heater Parts

Hello Joseph and thank you for writing . The typical cause for this is that the pilot light flame has become too far away from the thermocouple. ... Other potential causes are not having enough gas pressure or the pilot light/orifices are more restricted due to corrosion.
