What to do if your furnace wont ignite?
1) Turn T stat on and raise temp, so it delays then fan runs, gas valve opens (smell gas outside) but it failed to light after a couple tries then locks out and gas valve closed. 2) I had a new circuit with onboard ignitor card so I installed it.
Why does my Suburban furnace refuse to ignite?
10 ) I figure the sail switch and any limit switches are okay OTHERWISE the gas valve would never open nor would the HV create a spark. Fan runs, gas valve opens, HV ignitor throws a spark (albeit looks weak), get smell of gas out exhaust BUT THE DARN THING REFUSES TO IGNITE. I’m thinking maybe an ignitor problem?????????
How long does it take a gas furnace to ignite?
If this is the first time you’re attempting to light your gas furnace this season, it is important to know that a furnace ignition with a standing pilot light may take a while to light depending on the length of the gas line and how long it takes the fuel to reach the pilot light.
Where is the ignitor on a suburban furnace?
HOWEVER I noticed the ignitor tip was located near the burner center in a small area where there were no small holes where the gas flowed out. Soooooooooooo I relocated the ignitor tip right in the middle of 4 small gas outlet holes and set it at 1/8 clearance AND SHE FIRED RIGHT UP AND WORKS AFTER NUMEROUS TRIES.

How does an igniter on a gas furnace work?
Gas furnaces now come with an igniter that works electronically to light the gas and heat the home. These newer furnaces do not use a pilot-light system as the older furnaces did. If your furnace is equipped with an electronic igniter, you cannot light the furnace manually.
