Common paths to check

These are source-backed possibilities, not probability estimates for your specific unit.

  • 01 Official source meaning: External (room temperature) sensor short or open.

Decision path

Safe checks, in order

  1. 1

    Confirm code and model scope

    Compare the complete display and full model number with the cited manufacturer page or manual before applying any troubleshooting instruction.

    Expected: The official source explicitly covers the displayed code and product family.

    If not resolved: Contact manufacturer support with the full model and serial number.

  2. 2

    Follow the official owner checks

    No user-serviceable steps; professional inspection required.

    Expected: Only the user-accessible condition identified by the official source is corrected.

    If not resolved: Stop repeated resets and arrange qualified service if the code returns or the source directs service.

Reset and test

A user reset is not documented for this condition.

Important: A reset may clear the display but cannot repair the underlying condition; follow only the exact model-specific manufacturer procedure.

Escalation point

Stop and arrange service when

  • The code returns after the cited user-accessible checks or the official source directs professional service.
  • The equipment leaks, smells burned or of gas, smokes, sparks, overheats, or trips a breaker.
