A:AnswerMark, not sure about the charcoal filter but it does come with a stainless screen which is on the underneath of the microwave that you would clean every so often. Yes this can be used without duct work to the outside, that's how I am using it.
A:AnswerHello, the WMH32519HW is setup at the factory for recirculation venting. During Installation you can choose the best method for your home. The WMH32519HW can also be installed with wall vents or ceiling vents if they already exist, or you can install new venting if you prefer to vent externally.
A:AnswerOk. Just read user guide & yours may be in energy saving mode or standby mode. Look online or in user guide to reset so lights & stuff stays on.

A:AnswerHi Jeff, the WMH32519HT does not come with any filler kits, but we do have accessory Filler Panel Kits. This model is so new we do not have access to the documentation yet, but the Installation Guide will list the proper part number, it may even be the 8171338 Biscuit. But pleases refer to the installation Instructions to verify
A:AnswerHI Olson, the outlet must be above the WMH32519HV normally in a cabinet. If it is within its 30" width and close to the center, the cord will be long enough. Refer to the drawing on page 3 of the Installation Instructions and you will see where the recommended location is. It can be on the left side of the upper cabinet.
A:AnswerOnce a month just fill your sink with hot soapy water and let the filter sit in it for a while and rinse off. It will last forever if you do that.
