We are trying to determine the correct part that needs to be replaced on our dryer. It was in the middle of a cycle and it stopped. When we opened the dryer door the light did not come on and the display said "Call Service", we canceled the message and tried to start the cycle again and it says "Door Open". We tried opening and closing the door and also unplugging the dryer and re-plugging it back in and every time we attempt to "Start" a cycle it keeps saying "Door Open".

We are wondering if it is the switch that needs to be replaced or if it is an electrically issue and if so what part would it be that needs to be replaced?
