Samsung Oven & Range Error Code bAd LinE: Meaning, Checks & Repair
For the Samsung Oven & Range families covered by the source set, **bAd LinE** means **improper electrical power connection**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. 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 **bAd LinE**. Search normalization stores it as **BADLINE** while preserving the characters a homeowner actually sees.

Quick answer
Improper electrical power connection.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so BADLINE may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
For the Samsung Oven & Range families covered by the source set, **bAd LinE** means **improper electrical power connection**. The first useful step is to preserve the exact characters and model number before power cycling the appliance.

Signs
Symptoms you may notice
Depending on the exact model, the appliance may stop, restart, or refuse a high-load function.
When the bAd LinE condition is present, the code can appear after a surge, brownout, outage, incorrect supply, or frequency problem.
On affected Samsung oven or range models, some models preserve the display even when one required power leg or voltage range is abnormal.
bAd LinE can be accompanied by this pattern: bAd LinE appears on the range/oven and the related cooking, sensing, door, or control function can 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.
Before opening any service area, confirm the breaker has not tripped and the appliance is connected as specified by Samsung.
A safe owner-level check is to if the event followed an outage or surge, perform only the documented one-time power reset.
With bAd LinE recorded, do not perform live mains-voltage measurements unless qualified.
For bAd LinE, start by doing this: stop if breakers trip repeatedly, plugs/outlets overheat, or there is arcing.
As an external check for bAd LinE, record the exact code and model number.
The next non-invasive check is to verify door/divider/pan placement, vent obstruction, settings, and household power only when relevant.
Important safety warning. When working around an oven or range that shows bAd LinE, 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
Persistent power/voltage codes need the household supply and appliance power/control circuits checked safely before parts are replaced. A repeatable bAd LinE event is more useful diagnostically than repeated resets, because it shows when the improper electrical power connection check is failing.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
Temperature/sensor self-diagnosis code; can be benign during SmartThings self-diagnosis but may indicate a problem if it appears during normal cooking.
Resetting can clear a temporary state, not a persistent issue. If **bAd LinE** 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 **bAd LinE** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **bAd LinE** 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 **Oven & Range bAd LinE** separate from same-looking codes used by other Samsung appliance families.
