There are two main causes for this dimming:

1. Dust & other particle buildup on the front of the display glass and the rear of the display window. This can be cleaned.

Cleaning the display is easy, but you need to be careful so you don't break the glass.

First you would unplug the microwave or turn off its breaker.

Then see the video here that shows you how to remove your control panel assembly in less than 5 minutes.

Next, disconnect the keypad strip as shown in the photo below, then remove the screws that hold your circuit board in the plastic frame.

Then carefully (since the display is made of glass) remove your circuit board.

Using a soft cloth (since paper towels can scratch) lightly dampened with non-ammonia cleaner (since ammonia can damage some polycarbonate plastics), gently wipe off the front of the glass.

Then gently wipe off the back side of the plastic display window in the plastic control panel frame.

Reassemble, reinstall, and power it up, and it should be brighter, sometimes a whole lot brighter!

If that does not brighten it up enough, then...

2. Your vacuum display tube is wearing out and either the VFD display tube or the whole control circuit board must be replaced, depending on your model number, which you didn't mention.

If you'll contact me with your model number, I can give you an estimate and free do it yourself info.

Display on control panel is dim and hard to read.


If it's an LCD or LED display, it' may not be getting an adequate voltage from its driver I. C.. If fluorescent, it could be failing itself, or not be driven properly as well.

Based on other posts on this site,
The going rate for repair of these circuit boards seems to be about $39.

The display is too dim to read. what can I do?


Depends if it was dim when new then not a lot you can do
if it has gone dim , you have 2 options
1 unplug it and put plug in front of oven door,then remove all cabinet screws.locate the display control printed circuit (under display)take photo of wiring with phone to aid reassembly ,unplug and remove printed circuit board screws and board,clean display screen and window ,if was clear then either obtain replacement panel or take panel into radio or electronic repair shop and have them check and replace any poor electrolytic capacitors, this usually cures older ovens ,but if 6 0r 7 years old displays themselves dim and need replacing.ps if good at soldering just note these capacitor values uf and voltage and obtain at maplin and replace all observing polarity when fitting

Are you able to get a VFD separately for Maytag MMV4205BAW to repair dim display panel without doing the entire panel?


The VFD (vacuum fluorescent display) tube is not available as a separate part for this model, so you would have to order a new control circuit board.

For model MMV4205BAW, the board's Amana part number W10127098 and it runs a hefty $232.30.

BUT -
if you order the board by the original Samsung part number, you can probably get it a for a lot less.

Here is a photo of a similar board which is marked to show you where to find the full part number.

You can find links to helpful exploded view diagrams and part ordering help here.


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.


Once the controller is out, you disconnect the keypad, then take out your old board and put in the new one.

Some connectors may have a lock.

The Display is Dim. Hard to read the numbers.


I have the same model and problem. The time display is totally unreadable. Looking for a solution as well. I suspect given the cost (I believe around $60), it's time for a new one. Anyone have any suggestions or easy repair ideas?

Dim control panel unable to read


Removed the amber glass which obscures the display enough to remove the wiring from view. This also allows you to see the characters much more clearly. You now can see the inidvidual light elements.
It's not too bad, people don't even notice, but they do notice you can now tell the time and see what the oven is doing.

The digital display is very dim and hard to read even in the dark. Is there a way to adjust the brightness?


I have a Sharp Carousel 1.5kW microwave oven with model number R-310F(W)C. The LCD dispaly on my unit recently became very dim. After check the small circuit board on the front panel, I found that the problem is caused by the LCD backlight driver which drives three surface mount LEDs. As the LED driver is inside a chip built on a small daughter card, it requires a replacement daughter card, or the entire circuit board for display and keyboard. A simple alternative solution is to cut the link between the three LEDs and their driver, then build a small circuit to drive the LEDs. I can provide the circuit diagram if interested.
