Summit freezer shows E6 and the display or buttons may not respond correctly.

Safety first: Disconnect power before removing any control panel or display housing. Static discharge can damage electronics; ground yourself before touching boards.

Steps to troubleshoot E6:

• Power cycle: Unplug the freezer for 5–10 minutes, then plug it back in. If E6 reappears, continue.
• Access the display panel: Remove the screws securing the front control/display panel (often at the top front of the freezer or on the door). Carefully pull the panel forward.
• Inspect wiring harness: Locate the multi-pin connector or ribbon cable between the display board and the main control. Ensure it is fully seated and not damaged. Disconnect and reconnect to clean the contacts.
• Check for moisture or corrosion: Look for signs of condensation, corrosion, or liquid spills inside the control area. Dry gently with a clean cloth and allow time for complete drying.
• Examine the display PCB: Look for burnt components, cracked solder joints, or physical damage. If present, the board should be replaced.
• Replace the display board if needed: Install a Summit-compatible user interface/display board. Transfer any wiring harnesses one at a time to avoid misconnection.
• Reassemble and test: Reinstall the panel, restore power, and verify that the E6 code is cleared and that buttons and display respond normally.

Note: If E6 persists with a new display board and good wiring, the main control board may be defective and should be replaced by a technician.
