How does the vent work?

The vent doesn't seem to suck out the steam from our cooktop. A lot of the steam ends up blowing underneath our cabinets causing a steam mark on our walls. Do we not have the vent set up correctly? The microwave was in this house when we bought so we don't have an instruction booklet with it.
thanks

    Have same problem on Maytag MW(MMV6178AAW). Roof-Vented as per installation instructions. I called for assistance. Tech said it wasn't doing what it should, but he coundn't find anything wrong. This was 4 month after buying the MW. With MW so the blower can be seen and turned on the fans and sounds like lot of air movement, there is no are above the blower unit.

Under cabinet microwaves generally have two configurations for venting.
1) There is a vent cover plate on the top or rear (sometimes both) of the unit that can be removed and connected to a duct that vents up to the roof. If you do not have such a duct installed then that cover plate should be left on the unit so that it vents in configuration 2.
2) With the external venting ports sealed with the cover plate(s) the microwave simple draws air from the bottom (usually through 1 or 2 grease capture screens) and vents it out thought the front/top of the unit. This configuration isn't very useful as it just blows the air back into the kitchen. Many people don't both using the microwaves blower in this configuration.

I'm looking for a solution to a problem I already posted and have no idea wwhere it appears again? I have an over the stove model mmv4203 that wwas in the home when we purchased it; is there a charcoal vent in this unit as it appears it was not installed with an "up and out vent" thus the air just blows out into the kitchen from the top front of the unit. I don't really call this venting rather just moving air around. Anybody, anywhere with an answer? thanks, let me hear from you!

My microwave shuts off, black no power when ever I cook tv dinners, potatoes etc. after 2.5 or 3 minutes. After 10 minutes or so, power comes back on and it displays PF. lots of steam inside after.


Hi Kerry,
"PF" is power falure if you didn't aready know this. It sounds to me like the coolig fan might be running slow or there is blocked or restricted air flow through the unit. This cooling fan is only for the HV transformer and magnetron. Sometimes you may get air flow around the door but this is incidental. The PF tells me that the power is being interrupted either at the power source (wall outlet or circuit breaker) or the magnetron TCO is cutting out. It also could be a bad magnetron running too hot. As far as the steam goes, I usually just leave the door open on my microwave for 10 or 15 minutes to let the condensation evaporate.

It quit heating..just stopped..tried all the remedies on the help section--any suggestions? Worked great a few hours ago....have tons of relatives coming in tomorrow for a long holiday weekend? Model JVM...


The unit may have overheated due to no airspace sufficient to keep the sensor from shutting it down. If this was the problem ( defrost steam can cause this as well) it will recover

If you set up a fan and blow through the vents it will recover faster and your unit will be back in service.

The recovery time can vary that is why I have suggested the fan to cool it quicker.

Make sure nothing occludes the air vents in future and it is able to breathe.
If it does not recover in say 20-30 minutes then it may be the main fuse located underneath the exterior cabinet. Remove screws and external shell ,replace fuse and reassemble, that and you should be back on line if indeed that was the problem

Please rate my help++++ Thanks for using FIXYA

The exhaust fan is not 'sucking' air from the bottom of the microwave, it is pulling in air from the upper right of the unit. Why?


Not to be redundant , but there are two dampers on a microwave that is vented out. One attached to the unit and one on the exterior of the building. Have you checked both? I am from the mechanical side of appliances, not the technical side but i believe the large fan vents steam and odors from the cooktop and the small fan cools and vents the micro conpertment. I'll check with others and get back with you.

Our range venting microwave doesn't seem to **** up the steam from the range top. A lot of air comes out the top,but the steam seems to be going in.


We have the same problem with our lmvh1750st lg brand, there is 5 settings and alot of noise and airflow out the top. Very little from the bottom actually seems to go into the vent. We are very disatisfied with this and find during normal cooking we have very little help from the vent hood.

Acceptable distance from cook top surface to microwave?


Sorry but your subject line got cut off. I'll assume you're talking about the distance from the cooktop to the top of the microwave (bottom of the cabinet to which it's mounted).

Here's how the installation instructions spec it:
  • "Make sure the bottom edge of the cabinet that will be above the microwave oven is at least 66" from the floor and 30" from the cooking surface."
So it's measured from the cooktop to the top of the microwave, not the bottom edge.

And I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

You can also download your owner's manual form the link I posted above.

Installing a Whirlpool over the range microwave oven, just trying to figure out if I have to vent it outside or not. Instructions say venting outside is not necessary if you have a recirculation system....


I would say that you do not have to vent it outside. One of the most common complaints I get is that the microwave is not sucking up a lot of air. I have called Whirlpool and they have said that most of these newer microwaves don't really have a lot of air movement in them and they have smaller blower motors. Some of this was due to the fact that people didn't like the noise of a big fan that was necessary fo move air. I have noticed this on my own also. When boiling sweetcorn this summer, it would barely **** up the steam whether it was recirc or to the outside, I usually test them by putting a cleenex under the vent abd see if it holds it there. Bottom line is they really don't move a lot of air and it's not worth the cost and time of venting it out. Hope that helps

Recirculating over the range micro does not take care of steam


Mayny reason. Does it vent outside? If not you are not getting a great amount of air flow. Are you filters clean? Dirty filters will stop max air movement. These are not the best machines for moving air but they sure are great spacemakers. Not sure if this can be fixed by any means other than a true vent hood.

Exaust vent/ fan very weak


In your duplicate post, you mentioned your model, so here you go:

This is due to poor air flow, either to a blockage or a problem with the internal cooling fan or hood vent exhaust fan.

Are the grease filters or charcoal filter clogged?

You may want to check your owner's manual for info on checking the filters. Grease filters can be cleaned, but charcoal filters must be replaced about every 6-12 months.

The installation manual will tel you if there's some error in the installation setup.

Mircowave works, exhaust door opens, fan stop working


From looking at the owner's manual, it looks like the vent fan is only supposed to come on when the internal temperature of the microwave gets too high OR when you press the VENT FAN pad. Here are a couple of fan-related excerpts from the owner's manual, which can be found here: http://products.geappliances.com/ProdContent/Dispatcher?REQUEST=SKUOBJECTS&DOCUMENT=Use%20and%20Care%20Manual&SKU=JVM1840BD (or the better URL here: http://tinyurl.com/yn7r6g) Automatic Fan An automatic fan feature protects the microwave from too much heat rising from the cooktop below it. It automatically turns on if it senses too much heat. If you have turned the fan on, you may find that you cannot turn it off. The fan will automatically turn off when the internal parts are cool. It may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. - Vent Fan The vent fan removes steam and other vapors from surface cooking. Press VENT FAN once for high fan speed, twice for medium fan speed, a third time for low faw speed, or a fourth time to turn the fan off. Press the VENT FAN BOOST pad for extra fan speed. - Hope this helps.
