1965 Tempco Wall Furnace

fruitful Member Posts: 1
My father passed and was living in a cottage that has a very old Tempco Wall furnace that has not been light for over ten years. I bled the old gas from the natural gas line and was successful in lighting the units pilot light. However, when I raise the temp. on the thermostat the pilot light is extinguished. I believe that the thermo-coupler in the unit has gone had after all of these years of non-use. Where can I find a new thermo-coupler for a unit this old?

    50 years old, sat cold without pilot flame driving moisture out of heat exchanger and flue exhaust for 10 years? Could be a bucket of rust inside the firebox and inside the gas valve.

    I would call a pro to check out the entire unit.

    Gas valve may open and may not close completely. JMHO

    For the cost, I would just replace the unit. A pro could replace it more quickly than coming out to troubleshoot it, trying to find parts and then coming back to install them. New units are not that expensive and if it's not a vented unit you should change it out for one.

    What is the Model and Serial number, I have manuals on most of those and can give you some idea as to what should be done. A picture of the unit would help as there were many different Tempco heaters. As to thermocouple the Honeywell Q340 will fit most any pilot. I would also have that pro clean the pilot while it is out and then take some millivolt readings on the thermocouple.
