My tempstar furnace will not light - Jackson 25 in. TempStar HH-ST Free-standing Dishwasher

To restart your Colman Tempstar furnace, first make sure the power switch is in the "On" position. Then press and hold the reset button on the furnace for about 10 seconds to reset the system. After resetting, the furnace should start operating normally.

Keep letting it cycle through eventually the gas will make it through the small outlets. You will likely need to reset power. It took me about 10 start cycles to bleed one two days ago

Based on your model number this furnace does not have a pilot light,instead it uses a hot surface igniter.typically it glows and when it gets hot enough the gas valve will open and the burners will light.When the igniter starts to go bad it will glow but not get hot enough to open the gas valve.If your furnace lights and the quickly goes out the flame sensor maybe dirty.

HI follow the thermocouple lead back to the gas valve undo the silver nut foloow the lead back to the pilot and undone the nut on thermocouple or it may just pull out , or the burner might have to come out to replace it , if you arenot sure on this then a local gas fitter will do this .

Look for flashing light in bottom door and count flashes after furnace locks out. Read code or flashes with sticker on furnace panels.

try cleaning the pilot oriffice it sounds like the flame is weak
