Liftmaster CSW24U gate operator and moisture

Hi, new user here. Happy to be onboard.

I have a question for anyone familiar with Liftmaster gate operators. I live in western WA state, USA. My gate operator was installed in about 2017 and I'm already on my third motor. At around $500 apiece, that's no small investment. I'm trying to figure out why I'm going through these motors.

Long/short, I bought the assembly from a CA dealer but they had no installers in my locale so I wired and installed it myself. Worked great for about 4 years on a 5 year warranty. Then one day it started malfunctioning. After going through all the fancy digital diagnostics, eventually I figured out that the controller was working fine, but the motor was toast. I hit the remote button, no action. But then I tap the motor casing with a hammer, and the button remote opens the gate.

Liftmaster has been good enough to cover all my motors so far. They require that you send it to them for inspection, before they decide whether it's covered. So far all mine have come back faulty, from corrosion.

I can buy a heater for the CAW24U for another $200. I'm considering a 12" goldenrod dehumidifier for the motor housing, which I think would be a cheaper and effective alternative.

Anyone have any suggestions? I'm considering a weather cover for the gate operator but there are some site limitations. Anyone else have this problem with their gate operator motors?

Thanks for any advice.

Welcome to the forums.

Are you sure there isn't a seven year warranty on that unit ?
There is now.

What did Liftmaster recommend ?
Technically their heater based on recommended temperature setting wouldn't address the moisture issue.
I don't work on a lot of openers but have never come across a moisture issue.

Is that an open frame motor ?
It looks fairly well sealed in the pictures.
