How to use a fault code safely

  1. Confirm the model. Codes are model-specific. The same code can mean different things on two refrigerators from the same brand. Read the model number off the appliance data label.
  2. Write down exactly what you see. Record the code, any flashing lights or beeps, the power source (shore, battery, LP, generator), and what the appliance was doing.
  3. Do only the owner-safe checks. Leveling, closing doors, checking that LP tanks are open and breakers are on, clearing vents: these are listed on each code page.
  4. Stop at the boundary. Gas smell, flame or exhaust problems, 120 VAC wiring, control boards, refrigerant, generator internals, and jacks or slides under load are technician work.
