Samsung microwave -SE- / SE / TE: key/touch communication error
Check moisture and safe power-reset conditions, then know when to stop for service.
What this guide covers
Error codes: -SE-, SE, TE
This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

Safe troubleshooting sequence
This reviewed path begins with a direct owner-safe action or status check rather than a branching question. Follow the step below, then use the interactive diagnostic if the condition persists.
- Check the code and stop for unsafe conditionsRead the code from the display. Do not use the microwave if it is sparking, smoking or damaged; stop and seek qualified help. Never remove the cabinet or bypass a door interlock.
- Disconnect power safelyUse a safely accessible plug or the identified microwave circuit breaker. Do not move a built-in or over-range microwave to reach its plug. If you cannot disconnect power safely, prepare service help.
- Check for recent moisture before restoring powerSamsung says to allow the electronics time to dry after a spill or steam exposure. No fixed drying time is supplied. If you cannot tell whether it is dry, leave power off and ask Samsung for help. Otherwise, wait 60 seconds before restoring power once.
- Observe whether the code returnsRecord the exact code and whether it returns when power is restored or during normal use according to the owner manual. A cleared display alone does not prove the underlying issue is resolved. Do not keep repeating resets; if the code returns, continue to service.
Reviewed outcomes
Try one documented power reset
Samsung documents one power reset for a displayed error, with additional drying time if electronics were exposed to moisture. This is general Samsung support guidance, not an exact-model repair or a failed-part diagnosis.
Evidence strength: Strong
The code returned after the reset
The manufacturer guidance treats a persistent return of this code as a service condition.
Evidence strength: Strong
When professional diagnosis is the safer next step
The manufacturer guidance treats a persistent return of this code as a service condition.
Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
