Why a code is not a diagnosis

The code reports the condition the control detected; the underlying cause must be confirmed on site by a licensed technician using the manufacturer's procedure.

Safe things to observe

  • Note the exact code, when it appears and what the appliance was doing.
  • If the appliance has stopped, call a technician rather than repeatedly restarting it.
  • If you smell gas, stop, go outside and call your gas utility's emergency line or 911 before anything else.

Do not

  • Do not ignore a code that returns after a reset.

How professional service helps

  1. A licensed technician diagnoses the cause with the manufacturer's test procedure.
  2. Combustion and safety devices are verified with an analyser and the manufacturer's procedure after any repair.
