The SituationA homeowner in Cutler Bay (33157) returned after a storm to find the opener dead. Wall button did nothing; ceiling outlet had power. Remote LEDs blinked once, then silence.

On-Site Diagnosis

• Surge event: scorch marks on the logic board and a failed MOV protector.

• Motor windings passed resistance checks; board failure isolated.

• Photo-eyes aligned and functional; limit settings intact.

• No upstream surge protection and no battery backup.

What We Did

1. Installed a new logic/control board matched to the opener model.

2. Added an inline surge protector and recommended a whole-home protector via licensed electrician.

3. Tested UL 325 sensors, recalibrated force/limits, and updated remote codes.

4. Offered battery backup module to cover future outages.

5. Documented pre/post voltage readings and provided a storm-readiness checklist.

Parts & Specs

• OEM logic board; inline surge module; fresh remote codes; optional backup battery.

Compliance & Safety

• UL 325 verification completed; homeowners briefed on safe manual release protocol.

OutcomeOpener revived with clean, consistent operation. With surge protection installed, the system is far less vulnerable to summer lightning.

Homeowner Feedback

“Same-day board replacement and now we’re protected. Smooth, quiet open/close.”
