    Furnace help: dead 1993 tempstar furnace
    Hello, I have a Tempstar, direct vent [intake & exhaust] 90% from 1993: mod NUGS100BH04. On Nov 27th, I replaced the fan control box. It worked perfectly until yesterday morning. It kicked on for an hour, for the morning warm up, then it shut down before achieving the morning temp.

    Since then I have: replaced the thermostat, switched it to a different breaker, have over-road the safety switch on the side [completely bi-passed now], have tested the two leads on the fan door switch [both hot]. I am mechanically inclined, could wire your house from the ground up, but not good w fine electronics. I have also tested the new thermostat w the fan in "auto" or "on" modes, NOTHING, the fan will not kick on?

    Yes, the new thermostat is set for heat at 70 degrees & my house temp is now 50 degrees. Usually, when standing by the furnace, when I flip the side safety switch to on, the furnace clicks internally. But now, NOTHING. Please I need some help !

    Have you checked for good fuse in control board? First step of a furnace the inducer motor should come on (if it doesn`t nothing else will work)
    Try spinning it manualy,is it free spinning? If so get the multi meter out ,see if there power going to inducer,if yes,you probably have a bad inducer motor, if no,trace the wires from inducer back to origin,check for power at the contact of wires,

    ,, let us know what you find

My furnace starts up, I have it set for 70 or 72 and it stops producing heat at about 66. I shut it down and attempt to restart it and it gets to the electronic ignition spark but I don't get light off again? It has done this several times, it doesn't produce heat again until it cools off.

I have an 80+ tempstar with the smartvalve gas valve. During the call for heat, the inducer motor starts, but the ignitor will not come on and light. I checked the ignitor and it is good. I checked for voltage and it is good. Could the gas valve be bad, since the ignitor is controlled by the valve...
