There will be one of several micro switches that detect when various doors hatches and flaps are open or closed. These are usually recessed behind small slots in the casing. Each will have a corresponding spike or flange on the appropriate door hatch etc. carefully examine each of the movable pieces and look for evidence of a small piece that may have broken off or a "socket" that does not have a "plug" to fill it. Test these by carefully feeding a non-conductive probe (just in case) into the port and feeling for a little bit of springy resistance. If you find one, fold some light card into a tube that fits snugly into the hole and depresses the switch. Close everything up and try the machine. Hopefully you will find the missing link, then it is just a matter of making a semi permanent plug that you can remove when you need to.
