I've got a Trane XV-80 furnace that just tonight quit.

When starting the ignitor /sometimes/ glows but most of the time does
not...and either way the furnace does not light.

I can light it manually with a match and it will run normally.

The ignigtor appears to be OK...no breaks and the resistance is 130 ohms

What voltage do they operate at and is it AC or DC?



Looks like it must be the controller itself and I know that is going to
be expensive.
