My Mr. Heater control knob melted.

[Skunked-Rookie]

I was using my Mr. Heater and there must have been a leak because there was flame coming out from the tubes and it melted the control knob. The control knob will not move now that is has been melted.

Is there somewhere I can buy a new knob, or adapter?

Sounds like a product defect to me. Have you tried contacting the manufacturer?

You can order parts from the Mr.Heater web site. I had to replace my control knob because I messed it up while trying to tweek more flow. spendy little thing depending on which one $13 or $15.

No, I haven't. I've had it for awhile so its not like it is new.

Is it the Heater Cooker or tank top model? If so, it's the regulator in need of replacement.

Contact them, that is a bad deal, they will likely send a new heater or regulator out to replace it.

Its the one you can use to cook with also. The knob reads OFF/LO/MED/HI

[Ed Carlson]

Yes, that is also the regulator and presure controle. They should never meelt or get a back burn in them to allow a melt. I would contact Mr. Heater, they should make that right with you.

If not, then the control will cost you about $18 if you find one in a store.

I once had a bit of a fire from my connections where the hose and fitting from the tank hook up to the heater. It was not totally tight and it leaked a bit of gas from the loose connection and started a fire. I turned the tank valve off and tightened up the fitting and all was ok. The fire did melt an edge on my knob control but not enough to hurt it.

I do not know if this is where it leaked for you but this can and does happen.

I melted one once. Somehow the flame worked its way back to the tank. whole thing was a big fireball. I thought about fixing it, but just went and bought a new one and use the old one for parts.

Edit: I shouldn't say it "worked its way back". There were multiple ignition sources near and the bottom was lit inadvertently.

Dont know where the fire was..but one other thing.if you have a clog or partial blockage in the venturi it will cause it to burn back and you could have a flame coming out the round holes on the side of the pipe that runs from the regulator down to the burner. (that tube is the venturi)
