Seeing **E-22** on a Samsung microwave narrows the problem to **short temperature sensor error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **E-22**. Search normalization stores it as **E22** while preserving the characters a homeowner actually sees.

Quick answer
Short temperature sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E22 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

Seeing **E-22** on a Samsung microwave narrows the problem to **short temperature sensor error**.

Signs
Symptoms you may notice
Depending on the exact model, the control can stop or limit operation because a temperature reading is missing or implausible.
One clue that supports the E-22 diagnosis is that heating, cooling, drying, or defrost behavior can become inconsistent.
The E-22 display becomes more meaningful if the display may return at a similar stage each time the affected sensor is checked.
One clue that supports the E-22 diagnosis is that e-22 appears and the microwave may stop or limit the function associated with short temperature sensor 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 opening any service area, record when the code appears and whether the appliance had just heated, cooled, or defrosted.
To rule out an accessible cause, confirm vents, doors, filters, and ambient conditions are normal where they affect the sensor reading.
The next non-invasive check is to use the exact model manual before assuming the sensor itself is defective.
To rule out an accessible cause, 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.
As an external check for E-22, 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. Do not bypass a safety device merely to see whether E-22 disappears.

When to request repair service
Persistent temperature-sensor codes usually require resistance/connection checks at the sensor, harness, and control—work best done with the model-specific service procedure. If E-22 keeps returning, record the stage at which it reappears so the technician can test the short temperature sensor error path instead of replacing parts by guesswork.

Resetting can clear a temporary state, not a persistent issue. If **E-22** comes back, preserve the code and move to the safe checks or model-specific service path.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **E-22** should not be ignored if performance is deteriorating or the display keeps returning.
No. **E-22** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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-22** separate from same-looking codes used by other Samsung appliance families.
