Got a call about 5pm to say all the fryers are not working, so got changed and departed early in my car instead of the wife's, turn's out that the thermostats had not been calibrated so although working the temperature was far too low, easy to sort, remove the knobs and turn spindle by hand until the burner shuts down at the correct temperature, Ah but new problem still below temperature the pilots went out and could not be re lit, this is because the overheat stats are cutting out at too low a temperature, so bypassed them and got two of the 4 going, so we did get our chips, this is a pic of the Menu
