Error codeE-X1 (EX1)
ApplianceMicrowave
E-X1, also written EX1, is Samsung’s label for an additional open error. The entry sits in the table of codes for current-generation microwaves, next to the other letter-and-number codes.
Reset steps
Disconnect: plug or breaker.
Moisture present? Dry time. Otherwise, one minute (60 seconds).
Reconnect, then run the microwave and watch for E-X1.
If E-X1 returns
Request service at that point. Nothing under the cover is an owner repair, so a technician takes it from there.
Codes in the same area
The short counterpart is E-X2. Also look at E-81, a communication open error, and E-71, a steam sensor open error.

Phone (415) 969-6153 if the reset does not clear E-X1. Bring up the code, the model number and the steps you took, and look over Samsung microwave repair beforehand if you wish.
Model compatibility: Samsung reuses codes across series and model years, so E-X1 (EX1) may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
