Although I have never seen this microwave it will probably be similar to most. The lamp will no doubt be a special type and can be located by removing the cabinet by removing the screws and sliding back. When removed the lamp should be located and removed. Once removed you will then have the job of trying to find one the same but you can now show the repair shop the old lamp and supply the make and model number inorder to locate/order a replacement.
