Hello. I am restoring a 1970 Forester camper. It has a Duo Therm heater that is giving me fits! I know that the thermocoupler is working because if I bypass the pilot light and heat up the thermostat then the burners light and boy does the thing heat nice. I have isolated the problem as being the pilot light. I can get absolutely no gas to pass through the pilot light. I have taken it out of the unit, soaked it, sprayed air through it, etc. It has "PCB" and then a "1" stamped on it. Can I get a replacement for this anywhere? I hate to think I am gonna have to throw the whole thing away because I can't get the pilot light to work. I won't run it without the pilot light because that would just be stupid and dangerous. I have the pilot light all the way out of the unit and have disassembled it as far as I can without causing permanent damage. Any suggestions or ideas would be EXTREMELY appreciated! Thanks!
