Samsung Microwave code **E-23** is associated with **temperature t1 maximum-time error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **E-23**. Search normalization stores it as **E23** while preserving the characters a homeowner actually sees.

Quick answer
Temperature T1 maximum-time error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E23 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Samsung Microwave code **E-23** is associated with **temperature t1 maximum-time error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **E-23**. Search normalization stores it as **E23** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
A symptom that fits E-23 is that the appliance may stop or limit the affected function when the code is detected.
The E-23 display becomes more meaningful if the same code may return at a repeatable stage of operation.
Depending on the exact model, other symptoms depend on the model and the subsystem named by Samsung.
When the E-23 condition is present, e-23 appears and the microwave may stop or limit the function associated with temperature t1 maximum-time error.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before requesting service for E-23, record the exact code, model number, and operating stage before resetting power.
The next non-invasive check is to complete only the owner-accessible checks described in the model manual.
Before opening any service area, do not replace parts solely from a display code when wiring, conditions, or control feedback can create the same result.
A safe owner-level check is to record the exact code and model number.
To rule out an accessible cause, power the microwave off for 60 seconds only if Samsung's model guidance allows a reset.
As an external check for E-23, do not remove the outer cabinet or access internal high-voltage components.
Important safety warning. Do not remove the microwave outer cabinet. High-voltage components can retain dangerous energy even after the appliance is unplugged. For E-23, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.
Get help
When to request repair service
For E-23, the service threshold is straightforward: If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. Bring the exact model number and a photo of the display so the diagnosis stays tied to the documented Samsung code.
Book your repair
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **E-23** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Do not keep operating the appliance through a hazardous symptom just to see whether **E-23** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
The code alone is not enough to justify a part. **E-23** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Microwave E-23** separate from same-looking codes used by other Samsung appliance families.
