Why a code is not a diagnosis
The fault can be a loose connection, a wiring continuity problem, or a failed memory module. The manual's checks go in that order.
Safe things to observe
- Note the code; the appliance may run with default settings or refuse to fire until the module is restored.
Do not
- Do not open the appliance to reseat the memory module yourself.
How professional service helps
- A technician verifies the module connections and harness continuity, then replaces the memory module if the fault persists.
