Seeing **E-29** on a Samsung oven or range narrows the problem to **lower cavity sensor open**. 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-29**. Search normalization stores it as **E29** while preserving the characters a homeowner actually sees.

Quick answer
Lower cavity sensor open.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E29 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
Seeing **E-29** on a Samsung oven or range narrows the problem to **lower cavity sensor open**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation.

Signs
Symptoms you may notice
One clue that supports the E-29 diagnosis is that the control is not receiving an expected sensor signal or the signal is outside its accepted range.
A symptom that fits E-29 is that the appliance can stop a feature, limit operation, or repeat the code during the same stage.
When the E-29 condition is present, the affected function can behave intermittently if the signal or connection is unstable.
The E-29 display becomes more meaningful if e-29 appears on the range/oven and the related cooking, sensing, door, or control function may be limited.

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, photograph the code and note the exact operating stage when it appears.
Before requesting service for E-29, check only user-accessible conditions that can physically affect the monitored function.
A safe owner-level check is to avoid replacing a sensor solely from the display; wiring, connectors, supply conditions, and the control can create the same result.
The next non-invasive check is to record the exact code and model number.
Before opening any service area, verify door/divider/pan placement, vent obstruction, settings, and household power only when relevant.
For E-29, start by doing this: do not perform live high-voltage internal testing; request service if the code reappears.
Important safety warning. Stop for arcing, repeated breaker trips, uncontrolled heating, damaged wiring, or gas odor. Internal live-voltage and gas-system diagnosis is not a homeowner check. For E-29, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
If the code returns, model-specific sensor, harness, connector, and control-board testing is appropriate. If E-29 keeps returning, record the stage at which it reappears so the technician can test the lower cavity sensor open path instead of replacing parts by guesswork.

You can try the one reset Samsung documents for the model, but **E-29** 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-29** should not be ignored if performance is deteriorating or the display keeps returning.
No. **E-29** 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 **Oven & Range E-29** separate from same-looking codes used by other Samsung appliance families.
