Microwave exhaust fan

I am reinstalling the microwave and am wondering if i can turn the exhaust fan on top around to vent back into the microwave as opposed to the attic. some people told me it was an option on their microwaves, i lost the installation manual for mine and wanted to know if this was an option for me.

Re: microwave exhaust fan

In all my years, I've never heard of this. You would not want the grease and steam to go into the works. Can you give some more specific detail on what those others have told you?

Kenmore model 721 - Cooked a meal for 30 minutes. Afterwards the microwave did not heat. However, the next day it worked. A few days later, was operated for 20 minutes, and again did not heat, and has not...

Yes, there is a thermostat device located on the magnetron. It will open up (turning off the magnetron) when it gets too hot, and it will reset automatically after it cools back down (in 5 to 15 minutes). The question is, Why is is over-heating? Usually it is caused by the exhaust fan being turned the wrong way. (For example, it may be set to exhaust the air out through the top of the microwave, but you don't have a vent there.) That fan can be turned to exhaust air out the top, out the back, or recirculate the air back through the front of microwave. It's easy to turn it around - the hard part is that you have to take the microwave down to be able to pull the fan out and rotate it the right direction.

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

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.

Emerson microwave mwg9115sl over heats then turns back on after 20 minutes

Your magnetron is overheating, which can be caused by:

  • operating oven without cover(s) in place
  • wrong magnetron installed in oven
  • an old or otherwise failing magnetron
  • cracked magnetron magnet
  • improper power line voltage (should be 110-125VAC)
  • foods low in moisture (popcorn & bacon, e.g. - add 1/2 cup of water in rear oven)
  • failed or inoperable cooling fan or hood vent exhaust fan
  • deteriorating foam weatherstripping seals in air ducts or on outside cover
  • blocked air vents (dust, animal nest debris, insufficient free air space behind & around oven, etc.)
  • clogged or greasy charcoal filter or grease filter
  • blocked duct in hood vent exhaust

The first suspects in my book are fan failure, blocked vents, or bad magnetron.

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.\\

Can't remove the vent grill

Two problems found. The electrician that installed the micro. installed it incorrectly. The fan was supposed to be turned so that the exhaust would go through the pre-installed duct in the wall. To remove the grill, there is two screws on top of the micro. which have to be removed. The builder put in a deeper cabinet that covers the screws because it looks better. To fix it I have to drop the micro, take off the grill, clean it and all the grease off the micro., replace the charcoal filter, turn the fan so it will exhaust through the duct and reinstall the micro.

Noise of microwave exhaust fan

You can remove the exhaust turbine unit with one screw and reinstall microwave and buy a braun external exhaust unit that fits over the hole where it is at the roof or wall and all of the noise will be outside and it will actually work. It is weather proof and will **** steam or fumes out like the best vacuum cleaner.

Exhaust fan install

Well one may indeed be able to Relocate the fan to Vent out the back as long as it still does the exact same job as B4, & one is extreamely careful MW are leathal even when OFF.... however this means quite a bit of work.. As another sugestion, could you not use some of that silver Flexible Conduit and make a seal around the Fan and bend it to suit?
