Keypad or remotes work intermittently; sometimes require multiple presses.

Safety first: Stand clear of the door while repeatedly testing controls.

Steps:

• Replace batteries: Install fresh batteries in all remotes and keypads.
• Check antenna and location: Ensure the Henderson antenna wire is fully extended and not behind metal objects.
• Reseat connectors: With power off, open the housing and reseat the RF module and low‑voltage connectors on the control PCB.
• Replace RF module: If issues persist, install a new Henderson RF receiver module.
