I can't get my furnace to ignite and don't know what to check. It was a used furnace so I hav no manual
Again is this a spark or a glow coil? If it is a glow coil look at the coil and see if there is a crack or white spot on it. If so it needs to be replaced.
Coming from the induced draft motor is an orange or gray rubber tube leading to a switch pull the end off that is connected to motor and poke a wire or something to insure the hole is not blocked if it is not replace the hose. next step is to check the switch make sure if possible try to jumper 2 wires and turn unit back on if it works then either switch is bad or vent piping is blocked.. For your extreme Safety, Please Do Use Furnace in this condition until problem is fixed. thanks glad i could help

The blower motor stars, but it will not ignite.
The small inducer blower does come on but the furnace doesn't fire up. We've tried turning off the power switch and waiting several times. By the way this is a propane fueled furnace.
Many many thanks to both of you for your help, After many times of looking at this, he found thr problems. It was the orange tube. Thank you so much for saving us the cost of a repair visit. In todays economy, it was much appreciated.
Carldc3 hit the nail on the head. We have igntion and heat.
carldc3 was a godsend literally. My husband works out of our garage and without that furnace, it was in the twenties. Many many thanks to Carl.
