If the model number is correct, the part numbers for a door handle replacement is 56001139 and 56001136. There are two pieces with the door handle on this model oven. Replacements may be purchased at the websites listed in the link I provided.

If you have any questions, or if your model number is different than the one listed, please post back and let me know. I hope this helps you.

actually what problem u r having that u have to open the oven .can u explain.

Question edited for clarity. Question moved from Laundry Dryers. Check the circuit breaker or if it has a 13 amp UK plug, check the fuse inside the plug. There may be a fuse on the the control board, but getting to it is not safe. https://www.fixya.com/support/r29874712-repairing_microwave_ovens ..

More than likely the magnetron is the only fault.
