Monogram Microwave SE Error: Shorted / stuck key on touchpad
The SE error code (sometimes displayed as "5E") indicates a shorted key or stuck button condition. The control board has detected that one or more touchpad key contacts are continuously closed — as if permanently pressed — which prevents normal user input and locks out microwave operation.

Answer to continue safely
Is it safe to keep using?
No. While SE does not typically indicate an immediate physical danger, a shorted start key could cause the magnetron to energize unexpectedly. The microwave should not be used until the SE fault is resolved.
Can I reset the code?
Yes. A power-cycle will clear the SE code from the display temporarily. If the underlying keypad short remains, SE will return as soon as the unit scans the keypad again after power-up.
When to stop immediately?
Stop if you notice: Stop use immediately if the microwave starts a cooking cycle on its own without any button being pressed., Discontinue use if SE returns within seconds of every reset, indicating the membrane is continuously shorted..
Symptoms You May Notice
Microwave beeps continuously without user input
The appliance emits a rapid or continuous series of beeps as though a button is being held down, even when no one is touching the control panel.
"SE" or "5E" shown on display
The control panel displays "SE" or occasionally "5E" (which can be misread on 7-segment displays) and typically locks out all other inputs until the fault is cleared.
One section of the touchpad is unresponsive or hypersensitive
A specific area of the keypad either fails to respond at all or registers a press without being touched, corresponding to the location of the shorted membrane contact.
Display shows random characters or cycles menus
A stuck key can cause the display to scroll through menus, change settings, or display garbled characters as the control board responds to the continuous input signal.
Possible Causes
Deteriorated touchpad membrane
The inner layers of the membrane keypad can delaminate or fold, permanently shorting a key contact. This is the most common cause of SE on GE and Monogram microwaves.
DIY PossibleMoisture or food contamination under the keypad
Steam, condensation, or cleaning liquid that penetrates beneath the keypad overlay can create a conductive bridge across a key contact, mimicking a pressed button.
DIY PossibleControl board keypad scanning circuit failure
In rare cases the control board itself develops a fault in the key-scanning matrix, reporting a phantom key press. This requires board diagnosis or replacement.
Requires ProfessionalSafe Checks You Can Do
-
1
Perform a hard reset
Unplug the microwave from the outlet and wait 60 seconds to allow the control board to fully discharge and reset. Plug back in and check if SE has cleared.
On some Monogram models you can also press and hold the Cancel/Clear button for 3 seconds immediately after restoring power to force a control reset.
-
2
Inspect and dry the keypad surface
With the unit unplugged, examine the entire touchpad surface for moisture, bubbling, or visible delamination. If moisture is suspected, leave the door open and allow the panel to air-dry for several hours before retesting.
A hair dryer on the lowest heat setting held 6–8 inches from the panel for 30–60 seconds can help evaporate trapped moisture. Do not use high heat.

3
Press each key deliberately and release
After restoring power, firmly press and release each key on the touchpad in sequence. Occasionally a key that is mechanically stuck (not just electrically) can be freed by deliberate pressing.
If you can identify which key is stuck by the beep pattern or the character displayed, focus gentle but firm pressure on that specific key.
When to Call a Professional
Contact a qualified technician if:
- SE persists after keypad replacement, pointing to a control board scanning circuit failure requiring professional diagnosis.
- The microwave spontaneously starts cooking or changes power levels without user input due to the shorted key.
- Physical inspection reveals burn marks or melted areas on the control panel, requiring professional assessment before any further use.
