Dead cooker!

Here's the inside of the control panel of my lovely Everhot cooker, which is a glorified cast-iron storage heater which runs off a 13A socket. The fuse has popped, and the blue thing (?a transformer) is swollen and discoloured from overheating. Fingers crossed that a) repair is swift, and b) inexpensive. Until then, I can't even boil a kettle.
