Wall console unresponsive or displays error; opener shows E7

Safety first: Disconnect power before working on low‑voltage wiring to avoid shorting the control board.

• Inspect wall console wiring: Remove the wall console from the wall. Verify the two low‑voltage wires are securely attached and not shorted together. Check for frayed insulation or staples driven through the cable.
• Check polarity: At the opener head, confirm the wall console wires are connected to the correct terminals (e.g., WALL PUSH BUTTON or similar) as indicated in the Skylink manual.
• Bypass test: Temporarily disconnect the wall console wires at the opener. Briefly short the two wall button terminals with a small insulated jumper wire. If the opener runs, the wall console or its cable is faulty.
• Replace components: If bypass works, replace the Skylink wall console or run a new low‑voltage cable. If bypass does not work and E7 remains, the wall control input on the Skylink main control board may be defective.
