E6 displayed, interior light and display may work but compressor does not run.

Safety: Disconnect the freezer from mains power before opening any control housings. Capacitors on the PCB can hold charge; avoid touching components unnecessarily.

• Check basic power: Confirm the wall socket and plug are good by testing with another appliance. Inspect the freezer power cord for damage.
• Access the main PCB: On Hoover freezers, the main board is usually located in a rear lower compartment or behind the top control panel. Remove the cover screws and carefully expose the board.
• Inspect for damage: Look for burnt tracks, cracked solder joints, swollen capacitors, or a burnt smell around the compressor relay.
• Check connectors: Reseat all multi-pin connectors to the PCB, especially those going to the compressor, sensors, and user interface. Ensure no pins are bent or corroded.
• Test compressor output: With the unit unplugged, you can check continuity from the PCB compressor relay output to the compressor terminals to ensure the harness is intact (do not apply power directly).
• Replace PCB if faulty: If there is visible damage or if all peripheral components (sensors, compressor start gear) test OK but E6 persists, replace the main control board (PCB) with the exact Hoover part number for your model.
• Reassemble and test: Mount the new PCB, reconnect all plugs carefully, refit covers, and restore power. Verify that the compressor starts and the E6 code clears.

Note: PCB replacement involves handling static-sensitive components. If you are not comfortable with electronics, contact a qualified technician.
