Questions & Answers

Mh9B Pilot comes on but does not stay on as soon as you release gas turns off ?
Joseph for model number Mh9B
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.
The Fan quit working, It squawked and died. Can I get a replacement fan?
