In my ABI Monza circa 1977/78 I have an old electrolux gas fridge which has no model number on, but its white and grey with the controls underneath the fridge cabinet, consisting of a numbered dial and a push button. Someone who has one tells me just turn the gas on, wait a few seconds then press ignitor button. I havent done this yet, because I can see no way of telling how its lit having done this. There isnt a viewing window. Also as far as I can tell, the fridge only runs on gas. Has anyone got one? Can you help?
