Britannia cooker, no clock display and no main oven?

Hi all.

Had a power surge due to a faulty iron causing the house main RCD to trip. Oven was running at the time.

When I reset the RCD, the oven clock was dead and the main oven was also apparently not heating (orange temp light was off).

The main oven fan was running, the second oven was also still working (orange temp light came on) the gas ring igniters were also all ok.

Question – I assume the power surge damaged the clock / timer control. Would this also cause the main oven heating issue?

Thanks all.
