Before you begin
Safety first
This record preserves the manufacturer-stated fault meaning but does not expose internal service procedures. Do not open panels, test live voltage, alter wiring, handle refrigerant, or replace a component from the code alone.
- Photograph the complete code and rating-label model before cycling power.
- Confirm the exact model appears in the cited official technical guide.
- Stop use for smoke, burning odor, sparking, overheating, refrigerant or water leakage, or repeated breaker trips.

Confirm the legacy model and display
Compare the complete rating-label model and displayed code with the model list and fault table in the cited GE technical guide.
Expected: Both the complete model and exact code match the same official guide.
If not resolved: Contact GE Appliances support or a qualified commercial HVAC technician with the model, serial number, code, and guide link.

Keep checks external
Check only owner-accessible filters, visible airflow obstructions, and external unsafe conditions allowed by the exact-model owner manual; do not enter service mode or remove a panel.
Expected: No unsafe external condition exists and no internal diagnosis is required.
If not resolved: Stop using the unit and arrange qualified service.
Reset and test
A user reset is not documented for this condition.
Important: No universal reset is asserted. These technical guides are model-specific and their diagnostic procedures are intended for qualified service personnel.
Escalation point
Stop and arrange service when
- The complete model is not listed in the cited guide or the displayed code differs.
- The condition requires service mode, panel removal, live electrical testing, wiring work, or refrigerant handling.
- There is smoke, burning odor, sparking, overheating, leakage, or repeated breaker tripping.
