What the customer reported
The oven came on without anyone setting it, and when it was set deliberately it took too long to get to temperature. Two symptoms that sound unrelated, and in this case genuinely were two separate faults.
What we found
The control board was sending heat calls that nobody had asked for — that explains the self-starting. Separately, the igniters had aged to the point of slow light-up, which explains the long preheat. Replacing only one part would have left the customer with half a working oven.
What we did
Replaced the igniters and the control board, then ran the oven unattended through several cycles to confirm it stayed off when it was supposed to be off, and reached temperature in a normal time when called.
Why this happens
An appliance that turns itself on is not a quirk to live with — it is an unattended heat source. When a board starts issuing commands on its own, it gets replaced, not reset.
