Display shows E9 and the refrigerator may not cool at all or may shut down unexpectedly.

Safety first: Unplug the refrigerator. Do not attempt to open the sealed refrigeration system; that requires a licensed technician.

Access the compressor area:

• Pull the refrigerator away from the wall.
• Remove the lower rear access panel to expose the compressor and electrical components.

• Inspect start relay and overload: These are usually housed in a plastic cover on the side of the compressor. Remove the cover to access them.
• Check for burning or rattling: Gently shake the start relay; if it rattles, it may be burned out. Look for melted plastic or discoloration.
• Check wiring: Ensure all wires are firmly connected to the relay, overload, and compressor terminals.
• Replace start relay/overload: If visibly damaged or suspected faulty, replace the start relay and overload with an Insignia-compatible kit. Match the wiring positions exactly as original.
• Test operation: Reinstall the cover, restore power, and listen for the compressor starting. The E9 code should clear if the compressor starts and runs normally.

Warning: If the compressor hums briefly then clicks off, or does not start even with a new relay/overload, the compressor may be locked or internally damaged. Compressor replacement requires a professional with refrigeration certification.
