When using the main oven the appliance shuts down on a regular basis.
By shut down i mean the appliance becomes completly non functional.
Even the clock / display goes blank. By switching the oven isolator on and off it usually springs back to life. I have checked the supply from the mcb-
isolator -oven . ( electrician by trade ). The appliance is appx 4 years old .
Any advice would be much appreciated.
