Just purchased my home and inherited this Whirlpool microwave.It's works good other than the hood fan portion.It is hooked up to vent from the front,the blower(fan) seems to be in and pointed right although there is plenty of air out the top front,with clean filters there is very little draw above the stove.Is this common and a flaw in the design?? Or is there something that I can look for wrong?? Please advise on this problem,and do we need to vent it to the roof to fix this problem?? I will appreciate any answers you can give me on this matter,Thanks
Answer Michael, Proper installation, is very important for an "over the range" microwave oven. So we're sending you some information that should assist you. The hood fan is operating as designed, most likely, The blower fan moves approximatelt 250 CFM when on max speed, but at the same time it is "cooling" the interior components,so there is a big drop in the movement/circulation.
There is no power in my unit. Do I need a fuse?
Answer Hello Bill. You will need to test the thermal fuse W10138793 in the unit. It should read closed for continuity. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
