Remote controls do not operate the door; control board shows E7 or radio error; wall button still works.

Safety: Work with power off when handling internal electronics. Keep remotes away from children during testing.

• Check antenna: Locate the FAAC antenna wire or external antenna module. Ensure it is connected firmly to the receiver terminal and not cut or coiled tightly around metal parts.
• Verify receiver module: If your opener uses a plug-in FAAC radio card (e.g., XF or similar), remove and reseat the module. Inspect for bent pins or corrosion.
• Reprogram remotes: Follow the FAAC instructions to enter learning mode (press the radio learn button on the board) and add a remote. If the learn LED does not respond, the receiver may be faulty.
• Test range: Try operating the door from close to the opener. If it works only at very short range, the antenna or receiver sensitivity is compromised.
• Replace receiver module: If E7 persists and no remotes can be learned, install a compatible FAAC radio receiver or an external universal receiver connected to the push-button input.

Do not open sealed radio modules; replacement is more reliable than component-level repair.
