hot surface ignitor

[buggyman20]

My sister has a coleman furnace DGAA. I can not find the other numbers I wrote down. The ignitor was not glowing but was showing continuity. After checking everything else I ordered an ignitor and put it in. It lite right up. When I took the old one out it was warm to the touch even though the unit had been off several days. After watching it cycle I noticed the ignitor never stopped glowing. The user manual shows the ignitor turning off after 32 seconds. When I checked the unit the wires going to the ignitor had 122 volts to it all the time even when the unit was not running. Does that sound right? The unit cycles fine and the green light shows everything ok.

Check your wiring on the control box. Igniter will only have voltage for a short time at the start up of the heating cycle.
