We also installed three Mazon fans with built-in LED lights. On one of them, the lights quit working. When you remove the globe, you can see half of them barely lighting up when the switch is on. They have worked correctly for about 3 years, until now. Sometimes we can hold down the light button for the dimmer and it will come on full, then immediately go back off. I don’t think LEDs should go out that soon, and I also can’t seem to find a replacement light part for it.
