Thanks again. This was the answer! After resetting everything and replacing batteries, the remotes only worked for a couple more days with the original board. I purchased and installed the liftmaster external remote module and it works perfectly. As an added bonus... apparently the cheap...

Battery voltage was ~13v with minimal (~0.1v) drop while gate was actuating, so I don't think that's the problem. Ground wire was in place. Disconnected everything for 15 minutes and reset, and removed the WiFi inching relay that had been installed to eliminate potential source of...

Will check that. Current batteries are about 1.5 years old, I've typically gotten 3-4 years out of each set. When previous ones have died, the remote memory wasn't affected, the gate just stopped working or would stop partway through its cycle. Unfortunately the idea of using a separate remote...

Our previous tenants first mentioned the issue a few months ago (house is currently vacant). I can't think of anything significant that's changed w/r/t the electrical loads on the property. If replacing remote batteries and power-cycling the board doesn't solve the issue, I think wiring a...

Sounds like a sensible place to start - will try this first. I'll have to check on the ground. Per the wiring diagram, there should be a ground connected to the board, but I don't recall 100% whether this is present. The gate opener is powered by 12v batteries which are charged by a trickle...

Our rental property has a Liftmaster LA400 security gate operator. At least 20 years old, we had the control board replaced ~9 years ago. Lately it has developed an issue where the gate opener will "forget" the paired remotes roughly every few weeks or so. The opener will still work fine via...

Fair enough...but just keep in mind that aside from the cost savings, portable units are considerably simpler to maintain (fewer maintenance items, maintenance items more accessible) and offer better redundancy (can run on gasoline if your propane tank runs dry, can typically pull start if your...

Unless you absolutely cannot be without power for more than a moment (medical reasons), I'd look into a large (10-15kw running) dual-fuel portable generator. You could run lighting, fridges/freezers, internet, and one central AC unit at a time - not perfect, but 100% better than not having...

Beats me, they're original to the 1986-built house. We bought the house a few years back. There were some other oddities with the house electrical, but most have been resolved.

I have dual 150 amp main panels tied to a 320 amp meter base. One interlocked 50 amp breaker in each panel. One 50 amp inlet with hots split to each breaker, neutral and ground tied to one of the two main panels. Over 120 hours of running on this setup through various outages and has always...

This is timely - I'm in the exact same situation with the house we just purchased, except that we have dual 150 amp GE panels. Originally I was planning to designate one of the panels as the "critical circuits panel" and only have an interlock/inlet connection on this panel. However, going with...
