Breville Smart Oven Timer Will Only Set 9 minutes At a Time

Look at this thread for instructions on how to get the control board out of the oven.

Fixing the start button

If you scroll down far enough in the discussion, you will see that someone offered a better way to take it apart so that a series of 5 black screws aren't so difficult and remove.

The rotary encoder for the Time dial is the same as the ones used for the Function and Temp/Darkness selectors. They fail after a time and don't work at all but I suspect that encoder you've got is on the way out but hasn't completely failed yet.

I can verify that the encoder is a Bourns PER231-P19-N0010 low profile 23 mm 10 pulse/20 detents per revolution mechanical rotary encoder available from both Mouser and Digikey. At the time of writing this, only Mouser had stock on these so I ordered from them. Cost was just over $5 CAD so probably would have been ~$4 USD each on the US site.

If you want the US and not the Canadian Mouser and Digikey sites I think all you have to do is replace the .ca in the links with .com.

I recommend you replace all of the encoders at the same time because you never know when the other ones are going to fail in the same way. Replacing them on the control board is fairly straightforward and easy if you know anything about soldering and removing and replacing components on PCBs. There are only 5 legs on each encoder and they're easy to get at with a soldering iron without touching anything else.

I replaced the Temp/Darkness encoder on my control board which had failed completely with one I sourced at Mouser and now the temperature and toast darkness adjustment works again.
