If you have not replaced your thermal fuse then thats most likely your issue. If the lint screen goes in on the top the thermal fuse will be located on the back of the unit. You need to remove the back cover and you will see it. Its a white plastic fuse on the blower housing. Its part number 3392519 if its skinny and long and replace the cycle thermostat next to it 3387134. Also if the fuse is bad (can be continuity tested) then check your venting because the fuse will blow from venting restriction or defective cycle therm. Good luck. also im assuming that your ignitor is not glowing because the fuse will kill the power to the ignitor. If the ignitor glows then the only thing you could be looking at would that your gas valve is stuck shut.
