Before you act
Air conditioners: Do not open the cabinet, handle refrigerant, or test wiring based on a code summary. Avoid moving a heavy window unit; stop if there is water near electrical parts, smoke, or unusual heat.
These summaries describe the manufacturer's published explanation. They are not a remote diagnosis and do not establish that a specific component has failed.
