The display may be available but can be very tricky to replace----the issue could also be the voltage source to the display is down or low and the display itself is ok.

Lastly I have seen two units where there was in the menu a setting for how bright the display is.......

To try to locate the part Google the model number with "parts" or "display" etc.

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

Display very dim


Unplug the oven for five minutes and plug it back in, if the display is still dim you most likely have a bad smart board.

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?

Digital display lighting


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.
