Fuses are normally internal on Microwaves and opening the cabinet exposes dangerous voltages, even when disconnected. The fuses used are 'Ceramic' and look like this. However, just replacing it may not fix the problem, if you have a shorted component inside, it will need to be repaired by a competent shop/technician.

Hi

Press and hold the START/ENTER button for 15 seconds to unlock the control. Hope this helps...please post back with its complete model no for further assistance.

You unplug it fro 10 minutes to drain down the circuit, but if it doesn't heat the chances are that the Magnetron is defective, in that case a new oven is a good choice.

I hate to be the bearer or conduit of bad news, but IF the old (broken) door works, but the new door does not, the new door may not be the exact replacement part! Otherwise, the operation would be identical. Clearly, the problem is not with the microwave circuits because they work fine with the original door! Is there a flexible circuit strip that plugs to or from the door, to the control board in the main unit? If so, does it look any different than the original counterpart to it?

there might be a connector of some sort maybe a plastic part which gets in contact from door to the body telling oven door is closed and open.... seems like it doesn't recognize when the door is closed right now
