You mean NNS254? You can download your owner's manual here.

On page 4, it says, "If this appliance is to be vented inside the kitchen, be sure the charcoal filter kit is installed in the unit before you operate."

Also, on page 28, "The Charcoal Filter cannot be cleaned and should be replaced periodically every 6 to 12 months, or more often if necessary."

So the answer is "yes".

I don't know how to replace the charcoal filter on my Frigidaire FMV157GC microwave. There's also food between the grate and the glass on the microwave door. Help !


This is billed as the Use & Care Manual for the Frigidaire FMV156DC Microwave Oven:

ftp://ftp.electrolux-na.com/ProdInfo_PDF/Springfield/316495004en.pdf

Not sure it is the correct one but you will find instruction for cleaning the exhaust filters on page 19.

Below is the Use & Care Manual for a model direct from the Frigidaire site:

http://manuals.frigidaire.com/prodinfo_pdf/Springfield/316495057en.pdf

This is more helpful as on page 20 it includes illustrated instructions for removing the charcoal filter to change the oven light. Disconnect from power, remove the ventilation grate at the top to access the charcoal filter, slide back and lift to remove. With the grate removed carry out any required cleaning.

Is there a filter that can be repaced in this model


If your unit is set up to ventilate to the outside, there should be a metal grease filter, which should be cleaned in hot soapy water whenever it gets greased up.

It's important to be sure that your ductwork and outside vent flapper are clear, too. Animal nests can block them.

If it is set up to recirculate, it should have a charcoal filter in it, and those should be replaced (they cannot be cleaned) about every six months or so, depending on your usage.

You can download GE owner's manuals and installation instructions here.

You can find helpful exploded view diagrams and order parts (including filters) by entering your full model number here.

What does H97 code mean?


Sounds like your magnetron or inverter board.

Is your microwave in a cavity? If the microwave doesn't have enough ventilation space around it then the microwave is prone to overheating. Check your owners manual. Most require 6 inches on top, 4 inches behind, and 2 inches each side. No ventilation = magnetron or inverter will cook itself and fail.

Where we repair them in Australia our repair cost ranges from AU$100 to AU$120 but obviously depends on the model. Price in your location will be different.

Determine venting requirements


When you initially unpackage the microwave oven it is already set up for RECIRCULATION mode (which is VENTLESS). However, since the unit recirculates air rather than exhausting it out through the wall or roof, it usually uses a couple of small charcoal filters behind the upper grille and mesh filters on the underside that have to be changed or cleaned periodically. These filters will accumulate grease and dirt over time and should be periodically checked in order to maintain proper ventilation and air flow. Information pertaining to the location and care of the filters is explained on Page 4 of your Owner's Manual.

NOTE: If you wish to convert to a VENTED system, the instructions are listed on Page 4 of the Installation Guide.

If you do not have either manual you can obtain copies at managemylife.com. Just type in your model number as "GMH3174XVB" and you will find the manuals listed in a .pdf (Adobe) format that can be printed or downloaded for FREE.

If you have any questions, please post back and let me know. I hope this helps you.

Message to change filter but unit exhaust up to stack?


Grease filters change from the bottom side of the unit.

Charcoal filter is changed as follows:
To Remove Charcoal Filter
To remove the charcoal filter, disconnect power
at the main fuse or circuit breaker panel or
pull the plug.
Remove the top grille by removing the screws
that hold it in place and sliding the grille to the
left (opening the door makes grille removal
easier). Slide the filter towards the front of the
oven and remove it.
To Install Charcoal Filter
To install a new filter, remove plastic and other
outer wrapping from the new filter.
Insert the filter into the top opening of the oven as
shown. It will rest at an angle on 2 side support tabs
and in front of the right rear tab. Replace the grille
and screws.

Opening mmv5165ba to clean filters


Unless your Microwave is older, you have a problem. The newer electronic ovens require a lot of ventilation to keep their circuits from overheating. Further, I know of no microwave recipes that produce grease. You may want to get back to me on this.

Jenn-Air Microwave Bulb and Filters Inaccessible - Design Flaw - Help!


It's not a design flaw. The microwave was incorrectly mounted.

The installation instructions (installation kit) included a template for proper alignment of the microwave on the cabinetry.

If it had been aligned with the template, the two top grill screws would be easily accessible.

The grille must be removed to access the lights and the charcoal filters, which should be changed every 6-12 months if they are used.

If they are in place and not changed regularly, critical ventilation and cooling can be affected.

Your owner's manual can be downloaded free here, and it shows you how to change the bulbs and filter.

It will have to be remounted properly.
