Dale for Model Number JVM1660BB005 The only documentation I have is a one-page diagram for replacing the charcoal filter on the top. The one I removed (which is clean after 6 years of use) looks more like a '486 grease filter. So is the one on top a '7740 charcoal filter or a '486 grease filter? The diagram says to change the charcoal filter every 6 to 12 months which we haven't. I don't know if there are other filters.
Answer Dale, the grease filter part number WB6X486 is the two at the bottom underneath the microwave. The charcoal filter part number WB2X9883 is at the top of the microwave. Hope this helps you, thanks. Read More... Answered by AppliancePartsPros.com | Monday, January 12, 2015
