Our oven gave up the ghost a while back, or rather the oven display stopped displaying, which meant some fancy sleuthing required for this stumblebum. Judging by the heat damage to the board I was thinking capacitor drama as there was no marks on any components. So I ordered some new supply ones which I've fitted one at the far left here with the much larger one behind (weird that as they're the same value except the new one only rated to 400 V Vs the old one at 450 V, which I'm hoping is good enough), in hindsight that one was likely OK and just stressed by parts downstream, the two green capacitors to the right of the yellow transformer I replaced from my parts bucket, these were larger but are 100 V Vs 50 V originals (going up is no drama), I replaced one the other day when the line it was using only measured 7 Volt when 10 V was indicated on the board. That brought it up to 10 Volt but only resulted in a faint glow for the temperature side of the display, however that gave me hope.
When the ordered capacitor arrived I replaced that and the second of those twins on the right which supplied another power line, then got a lovely surprise when powering up the oven again, back in business and I'm chuffed too as I have grave doubts that it could have been fixed locally if I didn't do it.
