Called out to a house today. An 80 year old lady had a cooker put in 2 years ago which 'had never worked so I been using the microwave' (honest its true)
Checked the supply (30A rewirable) checked the switch (for some reason it was in the shower room next to the kitchen! Turned the oven on - nothing. Turned up the temp control - nothing. Turned on the first ring - oven light came on. Turned it off and oven went off.
I teried in vain to work out how to get at the controls, couldnt get the front off or the top. Eventually decided to check the connections on the back. It seems that the cooker for some reason had several different ways of connecting - even an option for 400V. It transpired that the installer 2 years ago had failed to connect a link on the neutral and the oven was being backfed somehow through the ring when it was turned on. Anyway old lady happy and cooker fixed.
Havent done much on appliances for a while just thought it was strange to have a 400V option on a domestic cooker?
