Replaced the igniter and the timer, electronics board
Timer was easy, about 20 min.
The igniter was a thrash. The nuts that anchor the igniter to the flame tube (?) were at an odd angle under the mounting. I had to use a combination of 1/4 " ratchet and simple box wrenches to remove them. And that was after having to dis-assemble the floor of the oven to get any clearance to work. the simple, nearly flat box wrench worked the best. A stubby version would have been even better.
Still.... saved about $300 doing the job myself and the oven works like a charm.
