SOLVED: " SE " error code Maytag MMV4203DS00 stainless MMV4203DW00 white MMV4203DB00 black MMV4203DQ00 bisque microwave oven keypad fix free repair tips

Unless there is grease or moisture, etc. on the control circuit board or keypad strip, the "SE" error means you have a shorting membrane keypad. Sometimes they can be intermittent, but replacement is the only solution.

NOTE: If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire. So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking.

 

The simplest way to fix this is a do it yourself solution, to replace the control panel frame assembly, which comes with a new keypad already attached.  

It is part number W10258190  "Panl - Cntrl" and you can order it from the Pros here * for about $174.15 (price subject to change).

NOTE: For those with other colors of this microwave, here are the model numbers and parts:

• MMV4203DS00 stainless W10258190 $174.15
• MMV4203DW00 white W10258189 $156.24
• MMV4203DB00 black W10258188 $156.96
• MMV4203DQ00 bisque W10258191 - no longer available (can use white above)

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

If you have any trouble getting the grille off once the screws are removed, slide the hood vent grille to the left about 1/4", then then pull it forward. On some models there are L-shaped clips that fit into a slot to hold bottom of the vent.

Some connectors have a lock. And be careful disconnecting the keypad.

 

 

Then move your board to the new panel assembly, but be careful since the display is made of glass.

Need more help? Instead of calling, please e-mail me with your full model number and FCC ID number from the tag on your oven, your detailed symptoms, and when they happen.
