The Problem
The oven had worked fine the night before. The next morning, it wouldn't ignite at all, no clicking, no smell of gas, nothing. The timing lined up with a monsoon storm that had rolled through the area overnight.
What We Found
Pulled the oven forward to access the back panel and tested the igniter directly. It was drawing no current at all, dead. The control board showed no other symptoms, which is consistent with a surge event: one component takes the hit, everything else keeps working.
The Fix
Replaced the igniter with an OEM-spec part, confirmed proper amp draw with a multimeter before closing everything back up, and ran a full heat cycle to verify consistent ignition.
The Result
Oven back to normal same visit. No signs of broader control board damage, which isn't always the case after a real surge, worth checking carefully rather than assuming.
