Most of the time it's the safety sensors — misaligned, lens dirty, or a wire pulled loose at the bracket. Painters and floor installers do this constantly. We normally start there. Occasionally it's a force-reversal calibration that drifted, or the door itself got heavier and the opener thinks something's in the way. Sensor check first, before anything else.

This happens often after a mesh-network upgrade or router swap. The MyQ travel module runs on 2.4GHz only — newer mesh systems sometimes default 2.4 to a different channel or hide it inside band steering. Most of the time, pinning a separate 2.4GHz SSID solves it. Give the unit 10-20 minutes to find the network. Worth checking before assuming the module is dead.

Almost never. The chirp usually means the cell hit end of life. In LA heat — canyon properties, attic-mounted units — cells last about 4-5 years instead of the rated 7. The opener still works on AC. Schedule the swap when convenient.

First check if the emergency release is pulled — sometimes a child or guest pulls it and the opener disengages. If the rail is engaged and you still hear clicking with no movement, it's usually a starter capacitor or main gear. Both are technician territory, neither is dangerous. Schedule it; the door is safe to leave alone.

Most issues can wait. If the door is stuck open and the property is exposed, call now. If a vehicle is trapped inside and you need it tonight, call now. Otherwise — battery chirp, intermittent remote, sensor alignment, MyQ disconnected, slow operation — almost always fine until morning.

Usually one of two things: the door got heavier (new insulation, new panels, swelled wood, lost spring tension) and the opener is hitting force threshold early, OR the limit switch on the rail drifted after a power blip. Sometimes it's a simple recalibration. Other times the door needs spring service first. We start with the easy stuff.

Often it's not the board — it's the bay. Attic-mounted openers and canyon-property garages in Topanga, Fryman, and Coldwater hit 105-110°F in August. The logic board reads it as a thermal fault and shuts down for protection, usually resetting after 20-30 minutes. If it's happening daily during a heat wave, the bay needs ventilation more than the board needs replacing.

Usually not. Power blips and brownouts can scramble the logic board's memory or surge through the low-voltage circuit. Most of the time it resets after a few cycles. If it persists, unplugging the unit for 60 seconds and powering back up clears most of these. Older boards from 2014-2017 occasionally take real damage from surge events — those are technician territory.

Almost always one of three things: (1) photo eye misaligned or dirty — most common, especially after painters, gardeners, or a bumper contact; (2) force-reversal calibration drifted; (3) the gate itself is heavier than the opener is sized for. We start with photo eye alignment + lens cleaning, then move to force calibration, then spring tension if it's actually a residential garage door. Loop detector issues are the equivalent on driveway gate operators (LA400 / LA500).

Press and hold the Learn button on the opener until the indicator light comes on (about 3 seconds). Then enter your new 4-digit PIN on the KPW5 keypad and press Enter. The opener will click to confirm. If the keypad isn't communicating with the opener at all, you may need to re-pair the rolling-code link — that's a 5-minute process. If you don't want to mess with it, we re-pair KPW5 keypads during any service call at no extra charge.

This is one of the most common service calls we run, especially in Brentwood and Studio City. The MyQ travel module runs on 2.4 GHz only. New routers often hide 2.4 GHz behind band steering or default it to a different SSID. Fix: in your router settings, give the 2.4 GHz network its own dedicated SSID, then re-pair the MyQ module. Tesla EMI from Wall Connectors charging at 48A can also desync rolling-code remotes — sometimes paired as a secondary fix.

Look at the indicator LEDs on both sensors. Both should be solid (not flashing). If one is flashing or off, the beam is broken or misaligned. Wave your hand 4 inches above the floor between the sensors while the door is open — door should NOT close until you remove your hand, then it should close normally. If it closes anyway or reverses on the test, sensors are out of spec.
