Samsung Microwave code **E-24** is associated with **over-temperature 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 appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **E-24**. Search normalization stores it as **E24** while preserving the characters a homeowner actually sees.

Quick answer
Over-temperature error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E24 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-24** is associated with **over-temperature 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 appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **E-24**. Search normalization stores it as **E24** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
One clue that supports the E-24 diagnosis is that the appliance can stop or limit the affected function when the code is detected.
E-24 can be accompanied by this pattern: the same code may return at a repeatable stage of operation.
E-24 can be accompanied by this pattern: other symptoms depend on the model and the subsystem named by Samsung.
When the E-24 condition is present, e-24 appears and the microwave may stop or limit the function associated with over-temperature 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.
To rule out an accessible cause, record the exact code, model number, and operating stage before resetting power.
For E-24, start by doing this: complete only the owner-accessible checks described in the model manual.
For E-24, start by doing this: 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.
A safe owner-level check is to power the microwave off for 60 seconds only if Samsung's model guidance allows a reset.
For E-24, start by doing this: do not remove the outer cabinet or access internal high-voltage components.
Important safety warning. When working around a microwave that shows E-24, keep the checks external and non-invasive. Do not remove the microwave outer cabinet. High-voltage components can retain dangerous energy even after the appliance is unplugged.

When to request repair service
If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. A repeatable E-24 event is more useful diagnostically than repeated resets, because it shows when the over-temperature error check is failing.

You can try the one reset Samsung documents for the model, but **E-24** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **E-24** should not be ignored if performance is deteriorating or the display keeps returning.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **E-24** before replacing anything.
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-24** separate from same-looking codes used by other Samsung appliance families.
