Question about Microwave Ovens

1 Answer

When turning Fan on (any speed), top vent grille blowing lots of air, but not pulling air underneath

Have never had or seen a microwave not pull air through the vents under the microwave. It's supposed to pull air through the vents on bottom of microwave and blow it out of the top vent grille to keep excess heat smoke from cooking on the stove from damaging the microwave and help filter the air so you dont smoke up your house everytime you make a grilled cheese sandwich. I have yet to find info on how to fix this. Can anyone point me to this information.

Some microwaves vent to the exterior. check outside for a vent. If it is a recirculating model, perhaps the filters are plugged, the vent pathway is blocked (packaging material) or a loose panel at the back so that the exhaust fan air is leaking out somewhere else. I don't know what else it could be unless the fan is loose on the motor shaft and the fan motor is running but the fan blades are not moving air.

There is a diverter in the vent area. You can pull it out and reverse it so that the exhaust blows up and not out into the room. The owners/installation manual will show you how.

SOURCE: JVM1790 Microwave GE-Draws air from bottom and top vents

1. You have to have exhaust pipe to connect m/w vent and this pipe has to be free from obstruction.
2. If it already connected and good, but air come from vent bar over door, then blow motor on top of the m/w was installed in wrong position ( motor has 2 -3 position depends which way air coming out up, back or front).
3. In this case you have to remove m/w from installation and change motor position.

Sorry to read about your problem, I hope this helps you out.

Well first of all I would take a piece of paper or newspaper, and put it up by the vents, the paper should be sucked on by the vent.. If it does that you have suction. if it does not hold the paper, you should get a warranty repair, i am assuming this new.

If the unit is install to far above the stove you may have a issue.

But long story short, the room vented units, do not really pull much smoke, they pull better on outside venting. you are just putting smoke/steam back into the room, just a little cleaner.

I tried to help you. Please help me and Rate/Vote on my response. We take the time to answer your question. take the time to rate us.Thanks and good luck

Internal fuse


Is this an over-the-range (OTR) microwave oven or a counter-top model? Assuming it is an OTR model, your can get to the fuse by first unplugging the microwave, then removing 2 to 4 screws over the grille vent. Remove the grille vent. Depending on the model, you either slide it to the left a little bit (1/4 inch) then pull it out, OR tilt out the top of it followed by the bottom. Now you should see 1 screw that hold the top of the control console in place. Remove it, then lift up on the control console to get past the tabs, and tilt out the top. Now, depending on the model, you may see the fuse behind the control console, or if it's not there, then remove the 1 or 2 screws that hold the metal grill vent that's located above the control console. Remove that metal grill, and your should see the fuse behind it. Sometimes that fuse blows for no good reason, other times it blows because you have a shorted high-voltage capacitor, or you may have a sticking "monitor" door switch.

GE Spacemaker XL1800 vent fan doesn't pull air from beneath


On the exhaust system (top of unit) there is a small metal 'damper' that is most likely stuck shut. If that is all clear then you have a problem in the duct work of the home.

The vent fan does not draw air from stovetop


There is a wire mesh filter and a carbon filter on the under side of the unit. IF they are plugged then it wont draw air. The other issue is this unit has a dual option for installing the fan. One is to vent to the outside and the other is to vent to the inside, if the fan is not installed for the correct usage, you have no airflow either.

Exhaust fan doesn't work and blows air from top vent


Some microwaves have a adjustable fan. We have one that you can vent out the back, the back top or through the front top filters. The latter is what it sounds like you have. If you take the small back panel off and lift out the fan motor you'll see that you can place it in the direction you like.\\

Recirculation fan does not pull in air/steam/smoke


The issue is that the fan on that unit is a reconfigurable fan. If there is a vent, you install the fan one way, if there is no vent pipe to the outside, you install the fan another way. https://www.manualslib.com/manual/294916/Maytag-Mmv4205.html?page=9#manual

Microwave oven exhaust fan


The Intake is gentle. It is not designed to have a great pull of air from the Cook Top.

TEST: Turn Exhaust Fan ON
Hold a sheet of your printer paper up to the INTAKE GRILLE (bottom). Will the sheet of paper stay? Held up only by the suction? If it does, Air Intake is OK.
