Electrolux Professional bntC

What does Electrolux Professional bntC mean?

bntC indicates a failure of the SkyLine oven's boiler SSR NTC temperature sensor (NTC4). The oven stops the boiler and blocks cooking and cleaning that need it, but it can continue cooking without the boiler. The manual attributes it to a temperature sensor issue affecting boiler operation.

Symptoms

• bntC displayed
• Boiler stops; cooking and cleaning blocked where boiler is needed
• Cooking possible without boiler functionality
• Boiler SSR temperature (NTC4) not read

Common causes

• Temperature sensor issue (NTC4)

Diagnostic steps

1. 01

   Continue without the boiler

   The oven detected a boiler problem; continue cooking without boiler functionality.

2. 02

   Verify cooking results

   Check the cooking results since boiler-based steam is unavailable.

3. 03

   Avoid boiler-dependent cycles

   Hold cleaning and cooking cycles that require the boiler until repaired.

4. 04

   Call Service if it persists

   If the problem persists, call Service to address the sensor.

When to call a professional

Contact an Electrolux Professional service centre when bntC persists. The NTC4 boiler SSR sensor is an internal temperature sensor on the boiler control path, and diagnosing it requires service access. While the oven can run without the boiler short term, steam cooking and boiler-based cleaning remain unavailable until a technician restores the sensor, so schedule repair.
