I have a lennox G16R Conservator III furnace and the unit will not fir up. It j=has been acting up lately where the ignitor would stay on for awhile but no main gas. But no nothing. I used to have to let it stay off for awhile then turn on. I have sanded the thermocouple, and check connections. It is sunday durning a snow storm here in MD.
What do I check to see if the control is bad. How do I get the unit to kick on for some heat for now?? Can I just apply power to the gas valve just to get the house up to temp.
