The display is not showing on the oven, and it is not switching on the heat. The lamp does work.
Is it likely that it is the controller board?
Are there any tests to try?
thanks

I can't find that stock number, but the problem is likely to be the
clock module, which is in effect the controller PCB.
That's particularly true if the clock is an vacuum fluorescent type
with 6 buttons like this.

They sometimes fail after getting progressively dimmer.
The faulty component is the large rectangular capacitor (often blue)
capacitor on the board.

The blue capacitor, swap it or swap the bigger electrolytics?
The type I was referring to has an X2 rated cap in series with the mains that acts as a "wattless dropper". Yours on the other hand has a conventional transformer PSU.
Is the fuse on the board intact?
Check the transformer windings for continuity with a meter on the ohms range.

I cant see a fuse on the board. There are no scorch marks. I will test the transformer tomorrow, I cant find my voltmeter, but I did find other things I had lost during the search.

Luckily Christmas Dinner was not at our house. I found a controller on ebay
for £20, new old stock. It came today and the oven is whirring away.
I found my multimeter yesterday, and was about to carry out the tests on th
e old unit before I posted this. The meter has gone again.
I was surprised that the controller costs around £100 new. Thanks for
all your help, the collective wisdom here is great.
Happy New Year
