How to Troubleshoot & Replace Whirlpool AP4299930 / 8206444A Charcoal Filter

Removed the old and installed the new 

Got the parts in less than 24 hours, and less than ten minutes later, voila! All installed with only a screwdriver. The hardest part was opening the mailing box! 

Ordered a replacement filter from Appliance Parts and installed it when it was received. 

Worked perfectly. Next day service. 

I replaced the Charcoal Filter. 

Took off the grill and installed the filter. 

Ordered a new part from AppliancePartsPros, which arrived very quickly, and installed the replacement. 

Unscrewed the cover, slid back the light cover, unscrewed the old bulb and screwed in the new bulb. For the charcoal filter, slid it back a little until could pull it up and out and slid the new one in place. Very easy. 

With quick service and so far the charcoal filter and the Vent Grill are fixed and working well. Just waiting for the Grease Filter to arrive. 

I ordered the microwave vent grill and charcoal filter for my model microwave. Received it in a reasonable amount of time. The two screws that hold the vent grill on were still up there, so I was able to unscrew them and put on the new grill with a little bit of coaxing for tabs to go in the right places, etc. But, I did it. I am 73 and proud of myself for making the old (12 year) microwave look like new again. My husband had a stroke and could not help. I did have to use a step stool to see the screws on top of the microwave and where to put them in. (I slipped the new charcoal filter in place first). I just matched my old parts to the new ones online with model numbers to help.
