Machine only starts if you shake the door. It is the type with push button door opening. I have changed the catch plate on the door, the interlock, cable and motor pecker assembly but it’s still the same. I’ve not yet tried changing the spring that goes to the button mechanism as I don’t think I have one to hand. I’ve had bother with these peckers and interlocks ever since they were introduced. Does anyone know any tricks for getting them to work reliably? 😕
