Freezer displays E8; interior light or control panel may flicker; unit may not power on reliably.

Safety first: Unplug the freezer and verify the outlet is de-energized before working on the power cord or internal wiring.

Steps:

• Check wall outlet: Plug a lamp or known-good device into the same outlet to confirm proper voltage and that the circuit is not overloaded.
• Inspect power cord: Examine the Insignia freezer's power cord for cuts, kinks, or burn marks. Replace the power cord if damaged.
• Access terminal block: Remove the rear lower panel and locate where the power cord connects to the freezer's internal wiring or terminal block. Tighten any loose screws and ensure no signs of overheating.
• Inspect control board: Look for burnt or swollen components in the power supply section of the main control board. If present, the board must be replaced.
• Re-seat connectors: Disconnect and reconnect low-voltage connectors from the board to the display and sensors to ensure good contact.
• Replace main board if needed: If the outlet and cord are good but E8 persists, install a new main control board matched to your model.

Note: If you experience frequent power surges or outages, consider using a surge protector rated for refrigerators/freezers.
