Samsung Oven & Range code **C-22** is associated with **sensor malfunction**. 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 **C-22**. Search normalization stores it as **C22** while preserving the characters a homeowner actually sees.

Quick answer
Sensor malfunction.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so C22 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 Oven & Range code **C-22** is associated with **sensor malfunction**. 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 **C-22**.

Signs
Symptoms you may notice
While C-22 is active, the control is not receiving an expected sensor signal or the signal is outside its accepted range.
One clue that supports the C-22 diagnosis is that the appliance may stop a feature, limit operation, or repeat the code during the same stage.
When the C-22 condition is present, the affected function can behave intermittently if the signal or connection is unstable.
On affected Samsung oven or range models, c-22 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.
As an external check for C-22, photograph the code and note the exact operating stage when it appears.
To rule out an accessible cause, verify 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.
With C-22 recorded, record the exact code and model number.
To rule out an accessible cause, check door/divider/pan placement, vent obstruction, settings, and household power only when relevant.
A safe owner-level check is to do not perform live high-voltage internal testing; request service if the code returns.
Important safety warning. When working around an oven or range that shows C-22, keep the checks external and non-invasive. 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.

When to request repair service
For C-22, the service threshold is straightforward: If the code returns, model-specific sensor, harness, connector, and control-board testing is appropriate. 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.
You can try the one reset Samsung documents for the model, but **C-22** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
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.
No. **C-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 **Oven & Range C-22** separate from same-looking codes used by other Samsung appliance families.
