The solution depends first on the type of display your microwave has. Please refer to the picture. The left side shows a partially defective LCD type display. If you have this type of display, we regularly repair them for $32.50 nationwide. The right side is a VFD type display which is weak due to age. On some brands and models, we are able to get a replacement display tube and repair it to a like-new brightness. Feel free to e-mail me at _ if you have other questions.

My Oster OGB81102 microwave oven's display is too dim. Is there any way to brighten it?

Behind the display module there is a capacitor. It needs replacing. They bulge, split and fail.

The clock light on our JVM6175 microwave is very bright. Is there a way to dim it?

As some others have suggested elsewhere, I purchased and applied Display Dimming Film available online. I suggest using a single piece that completely covers the opening (will probably require trimming to fit) rather than having two or three smaller pieces abut, otherwise sparkles of light will shine through the spices. Once you have this film, you will likely find other uses for it. For example a digital clock near a TV, or a overly bright power indicator light on desktop computer speaker, or the power indicator on the desktop computer itself that stays on in standby mode through the night.

The control panel of my sharp grill 2 convection microwave oven is very dim

Hi,
Dimmed light might be caused by a slight contact between the panel's connector and the mainboard. Or, there is a dimmer option (feature) in the menu. Depends on model. Some of Panasonic microwave ovens are equipped with such a feature.
Regards,
Dan

Whirlpool 6mt 42 microwave oven digital display

It's probably a weak VFD tube but it may be that the rear of the display window and front of the display glass are very dusty.

Sometimes you can clean it inside to brighten it up.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you can detach the keypad connector (as per attached photo) then remove the control panel screws.

Be careful not to crack the glass display when handling it, or it's a goner.

Then you can use a soft cloth (not a paper towel) and a mild cleaner (not ammonia-based) to clean the front surface of the VFD display glass and the rear side of the clear bezel (display window) that's attached to the keypad.

Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.

I always recommend that you spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

Some connectors have a lock.

positivelock.jpgIf that cleaning didn't help, then you have a weak VFD.


On a Whirlpool microwave, the VFD tube is almost never available separately, so if it's bad, you would have to replace the entire circuit board.

You can find links to helpful exploded view diagrams and order parts here.

I'd recommend that your bookmark this link to your favorites.

Sparking / Popping Microwave

GE had a rash of "underperforming" magnetrons on these units. They replace the magnetron, stirrer and high-voltage diode at no charge for parts as long as a GE-authorized service center does the work. Sometimes the unit gets run too long in a failing state and the waveguide and chassis of the oven get damaged. To see if yours is covered, see this bulletin: http://www.microwavedisplay.com/ge_mw_mag_kit_bulletin.pdf Otherwise, you need to contact GE Customer Relations at 1-800-386-1215 as soon as possible and tell them your problem and they will put you in touhc with a local authorized servicer.
