Have you tried something like a LiftMaster 365lm? I have an older garage door opener that I got for free, but the receiver board appears to be bad. I installed one of those up next to it and it works well. If you where to put it further away from the lights such as by the door, or perhaps even up in the soffit it might do what you want to do without replacing any of your garage door hardware.

I looked at this item. If the ferrites don't help I'll try one of these. None of my conversations with suppliere or Liftmaster mentioned this item. Thanks Aaron.

I would just change out those light fixtures to LED

Try ferrite choke (not core) on the lights as noted, but not the one shown from Mcmaster. You see these on a lot of power cords for electronic devices. Digikey or Mouser or one of those type places.

ferrite core cable - Google Search

This should look familiar to you. The round thing on the cord is what you should try.

I use the snap on ferrites to cure my problems when I operated on my HF radio I would turn the light on as well as open the door at times! Solved the problem!

Yes, what these two gents said. I'm not an electrical guy and couldn't think of what they're called.

In High Bay lights there are a lot of LED choices. Some reasonably priced, some not. Some use ballasts, some do not. Some LED bulbs are reasonably priced, some are not.

A Wrecker Service near me is completing their new shop. They used the same ballast fixtures that I have. They have LED bulbs. Immediately had bulb failures, lots of them. Finally converted the fixtures by removing the ballasts and buying expensive LED bulbs that have their starter self contained. Cured the bulb problem at a very high price. They have 7 Liftmaster openers. 5 along the South wall. 2 at each end of the North wall. The 2 at the North side act just like mine. The 5 along the South wall have short but tolerable range. Their problem is they talk to each other. Supplier/Installer is saying RFI.

I should have them on Thursday. I'll report my results.

Got them yesterday, installed today, no change.

Talked to an Electrical Contractor today. Said he has two buildings with same equipment, same problem.

One last thing I'm going to try. My shop is 35ft from my transformer and meter pad. They are grounded with a copper rod driven into the soil. I did not do that at my shop. Tomorrow I'll add a ground rod. I'll report my results.

May end up there. Will that fix my problem?

Will cost me $500 to convert these fixtures to LED non-ballast. Would like to know that will fix this before spending that money.

I put these in my shop and really like them. I can't tell you whether or not they will fix your problem, though, but if they don't, I'm sure you could take them back if you have a Sam's nearby.

That looks like a good solution.

My openers and lights are hooked up, but they haven’t programmed the remotes yet. Should be able to see if there’s any difference in the next few days.
