Whirlpool AKZ 531 oven control board/power unit

[Blitherer]

Hi,

My built-in oven is permanently on (I have to switch it off at the circuit-breaker) and it seems one of the relays is heat-damaged and the contacts are welded closed. (See image). The control-board is part number 4619 615 12252 which I can no longer find. I have decided to replace the (very cheap) Omron relays which are currently in the post, to see if this solves the problem but perhaps there are other parts damaged.

If the new relays do not solve the problem, does anyone know of correct equivalent control-board?

Thanks

The Whirlpool page for your model number shows different parts for control & power units neither of which resemble your pics.& are both pricey items. However I think your diagnosis of welded relay contacts is probably correct & replacing the relays would be the way I would proceed after checking the thermostat has stopped conducting in the off position.
