Later during a conversation with our son, he suggested turning off the

it anyway. Low and behold the oven settings are now back to normal, the
heating digit lights immediately and the chosen temperature setting is
maintained.
This may not work for everyone but it is worth a try before committing

This solution works for many electronic devices. Computer, phone,
sewing machines, modem, cable box, etc. Overnight is not needed,
usually 15 seconds is enough.

You are forcing a 'cold start' on it, and if the software is in an
uncertain state that SHOULD restore it to normal.

Note that random cosmic rays carry enough energy to occasionally corrupt
DRAM..

And any serious EMP from switching or transients on the mains can do
similar.
