how to identify a microwave lamp for professional replacement
record when the interior light fails to operate and give the full model to a microwave service technician. internal lamp replacement is not owner maintenance: dangerous stored charge can remain after unplugging.
the linked supplies have different mounting bases or brackets and terminal layouts. flat, straight and l-shaped versions must not be swapped or adapted simply because a bulb looks similar.

scope: do not remove the cabinet, pull out a built-in appliance for a label or run the microwave empty. a lamp-and-bracket set is different from an integral-base lamp; the technician must compare the exact supplied item.
diy warning
working on appliances can involve mains electricity, water and moving parts. always disconnect power and water before you start. in Australia, gas work must be done by a licensed gasfitter, and fixed (hard-wired) electrical work by a licensed electrician. everything on this site is guidance only, and any repair you carry out is at your own risk. we are not responsible for any damage or injury caused by attempting a repair. if you are not confident, please use a qualified technician.

steps
- check normal light use
read when the manual says the light should come on. don't run the microwave empty to test it. note any changes to the display, heating or door operation without opening covers.
- record the model
photograph an accessible appliance label or use the paperwork. don't pull out a built-in microwave to find its label.
- arrange the lamp repair
give the model and symptoms to a microwave technician. have them compare the product page, mounting and terminals: straight, flat and right-angle versions cannot simply be swapped or adapted.
- check after service
the technician must complete the model's fitting and safety checks. the light should then work at the times given in the manual; other faults still need service.
