Can I check the exhaust fan on my Microwave Hood Combination that does not draw steam up into the unit?

I purchased a Kenmore Elite Ultra Wave Microwave Hood Combination 5 years ago and it does not draw the steam from the stove top. It blows air strongly from the top of the unit. I would like to know if an improper installation could cause this. The steam from the stove top goes up within the hood but is not drawn up into the vent. It goes over and up the sides of the vent bypassing the filters.

On this unit during installation you do adjust the direction of the exhaust. When the unit is shipped the default direction for the air is to recirculate the air back into the room. During installation you can keep this or change it to the top or to the rear. No matter which direction is chosen it should draw the steam up into the filters.

You said that the fan blows strongly from the top vent. Your filters could be clogged. You might try to remove the Charcoal filter and the grease filter and see if the steam is drawn up into the vent body. Your owner manual will show how to remove the filters.

The damper plate on the air deflector could be stuck but that would not be serviceable item. Microwaves are inherently dangerous to service. Internal capacitors can retain a lethal electrical charge even when the microwave is unplugged. A microwave radiation leakage test must be performed on the unit following any repair. I recommend calling a service technician to repair this type of problem.
