Lightning Took Out the Opener in Doral 33178 — Board Failure, Surge Protection, and a Clean Re-Start

After an afternoon storm in Doral 33178, the opener lights blinked but the motor wouldn’t engage. We traced a fried logic board, installed surge protection, and restored safe, quiet operation the same day.

South Florida Scene-Setter

Frequent lightning and power spikes make surge protection and battery backup essential for garage openers in HVHZ areas.

The Problem — Voice of the Pro (Ethan Cohen, Diagnostics & Safety Specialist)

“LEDs blinked a pattern consistent with board failure. I isolated power, inspected wiring, and confirmed the motor windings were OK.”

Safety Box:

• Power down before inspection.

• Never bypass photo-eyes.

• UL 325 protections must remain enabled.

Diagnosis — Method & Checklist

• Verify line voltage and GFCI.

• Inspect wall control, safety sensors, travel limits.

• Open housing; test board for visible damage and smell.

Symptom → Cause → Risk → Urgency

Symptom	Likely Cause	Risk	Urgency
Blinking LEDs	Surge-damaged board	Inoperable door	Immediate
Motor clicks only	Failed relay/board	Stranded vehicle	High
Random reversals	Sensor fault	Entrapment risk	High

Solution — Step by Step

1. Installed manufacturer-approved logic board.

2. Added surge protector and battery backup.

3. Re-paired keypad/remotes and Wi-Fi app control.

4. Re-aligned sensors; verified auto-reverse and force limits.

Results

• Consistent start/stop; Wi-Fi control verified.

• Post-storm resilience improved with surge protection.

Social Proof — Review Patterns

Homeowners praise same-day electronics fixes and guidance on surge and battery options.

Owner’s Note — Moshe Gueta

“In storm season, protect the electronics. It’s cheaper than replacing a motor.”

Pro Tips

• Whole-home surge protection adds another layer.

• Test battery backup twice a year.

• Keep sensors clean and aligned.

Mini-FAQ

Does smart control add value? Yes—security and convenience.Replace or repair? Board swap is efficient if balance and motor are good.Battery life? Typically 1–2 years depending on cycling.
