Samsung Microwave code **E-26** is associated with **temperature-not-over-ad error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **E-26**. Search normalization stores it as **E26** while preserving the characters a homeowner actually sees.

Quick answer
Temperature-not-over-AD error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E26 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-26** is associated with **temperature-not-over-ad error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **E-26**. Search normalization stores it as **E26** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
E-26 can be accompanied by this pattern: the appliance may stop or limit the affected function when the code is detected.
While E-26 is active, the same code may return at a repeatable stage of operation.
When the E-26 condition is present, other symptoms depend on the model and the subsystem named by Samsung.
Depending on the exact model, e-26 appears and the microwave may stop or limit the function associated with temperature-not-over-ad 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.
For E-26, start by doing this: record the exact code, model number, and operating stage before resetting power.
As an external check for E-26, complete only the owner-accessible checks described in the model manual.
A safe owner-level check is to do not replace parts solely from a display code when wiring, conditions, or control feedback can create the same result.
Before opening any service area, record the exact code and model number.
With E-26 recorded, power the microwave off for 60 seconds only if Samsung's model guidance allows a reset.
Before requesting service for E-26, do not remove the outer cabinet or access internal high-voltage components.
Important safety warning. Safety takes priority over clearing E-26. Do not remove the microwave outer cabinet. High-voltage components can retain dangerous energy even after the appliance is unplugged.
Get help
When to request repair service
If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. If E-26 keeps returning, record the stage at which it reappears so the technician can test the temperature-not-over-ad error path instead of replacing parts by guesswork.
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-26** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
The code alone is not enough to justify a part. **E-26** 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-26** separate from same-looking codes used by other Samsung appliance families.
