Gas furnace prob, ignitor out?

I have a small house, and I think its mainly a mobile home furnace. The furnace itself sits on the ductwork, and the label inside says its a Category 1 furnace. It shows a model number of DGAH077BBSA. It has been working no problem this season so far, but tonight I noticed it was getting cold in the house. I checked and it goes through the whole start-up cycle okay, but I never see the glowplug light up nor does it ignite. It shuts itself off and LED flashes an ignition error. I have worked on this same furnace before, but I am wondering if this is something simple and if I can work on it myself. Any help or advice is appreciated. Also, can anyone tell about how much an new ignitor would be and where I might get a new one? Would Home Depot or Menards carry such a thing?

What is the code of the flashing error it's giving, and look that code up on the manual with the furnace, or should be something on the wire diagram or igntor itself.

No, you won't find the ignitior at Home Depot or other home centers..

If you had heavy snow fall, make sure the roof vent is clear.

Thanks for the advice but...

All it says for the LED flash code is what I put in the original post, Ignition Error. Also, I havn't had much snow, but either way wouldn't the fact that I don't see the glow of the igniter in the little window show that its not working and therefore I can save myself a trip up to my icy roof?

The chances that the ignitor is burned out are good. You can usually unplug the ignitor and check the continuity with an ohm meter, or you can remove and inspect the ignitor for a crack.

No you wont find ignitors at the typical hardware store.

You can shop around on line or look for a furnace distributor or repair outfit to sell you two ----one to have on hand for the next time.
