Oven would not ignite

Step one - Diagnose. Used a clamp-on ammeter around the igniter lead to check if 3.6 amps or greater were present during ignition. Only about 2.5 amps were measured, indicating that the igniter was bad.

Step two - Ordered the part.

Installation - Removed the racks and bottom oven compartment cover plates, exposing the igniter/burner assembly. Removed the bottom drawer, cut the wires of the existing igniter (leaving plenty of wire left for the new one). Removed the igniter/burner assembly through the oven compartment. Removed the old igniter from the burner, installed the new one. Re-seated the igniter/burner assembly, routing the wires appropriately. Stripped the existing leads (cut in previous step), spliced the new leads in, soldered the connection (soldering is optional). Taped up the splices with electrician's tape. Turned on the oven to verify that the new igniter glowed and the burner lit. Turned off the oven and waited for the burner to cool. Replaced the bottom cover plates and rack.

Final step - Baked some bread.
