Need some help, I have an old natural gas space heater, the info is as follows:
DUO-THERM, Div of Motor Wheel Corp.
S/N 1769A87, Model 1410-6, Control - SP.
The problem is the pilot light will light and stay on until I place the switch to the "ON" position and try to increase the gas (turn the falme control to warmer). I think its the thermo coupler/built-in safety, Does that make sense? If so where in the world can i find one and replace it, or is there an universal type I can install instead. Thanks in advance for your help,
It may be the thermocouple which can be purchased at any hardware store or the pilot flame can be partially plugged resulting in a weak flame. When main burner fires up the flame on the pilot tends to vere away from the t-couple and knock out the system. Pilots usually should be removed and cleaned every 2 years or so.
