Got the owner's manual to see if there was a spec for the light since the lettering was not readable. No luck with the manual. Went to Home Depot to see if they carried the light - again no luck. Went on line and found the light designation. AppliancePartsPros.com had the light in stock as well as the Charcoal Filter that the owners manual mentioned should be changed on a regular basis. This is an old Maytag cabinet mount microwave. I ordered the parts online Tuesday morning and received them Wednesday evening. Nice job AppliancePartsPros!
