No reference matches. Check your exact model’s manual or ask the manufacturer. Do not assume a similar code has the same meaning.
Record the evidence before a service visit
Note the full model, the exact letters and numbers, when the symptom began, any visible leaks and whether a power outage preceded it. If a code is visible through an existing viewing window, record the sequence without opening the cabinet. The Carrier references below use short flashes for the first digit and long flashes for the second on the specified control. Whirlpool formats vary; use the linked manufacturer reading guide and your model manual.
A code identifies a detected condition, not necessarily the part that needs replacement. Internal testing belongs to a qualified technician. Use safe symptom checks or review the safety limits.
