After some help here, I replace an igniter. Was $47 all told and it came with pigtails and molex connector.
Had to get at the connector from the bottom, after removing a couple of sheet metal panels.
Now the question: should the igniter stay ON, as long as the oven is set to some temp? The igniter for the broiler does.
Never paid any attention to it, until now.
I ask, because the heating furnace igniter goes off, as soon as the gas is ignited. Could last longer that way.
