Just moved into a new rental property and getting used to the place. 

Partner realised that the oven display is broken and there's no way (as far as we can tell) to turn off the oven light. Oven works fine with those pop-out dials, but would be nice to be able to turn off the wannabe nightlight. Switching it off at the wall does nothing. 

The model no. on the instruction manual is: BOHF160SSPT. Polo electric oven. Struggling to find this exact model online. 

Is this something I can fix myself or leave it to the experts?
