fan speed indicator lights occasionally blink in unison.
I have to turn the breaker off to reset them.
Here's what the installation guide says:
FILTER CHANGE INDICATION
After 30 hours of fan operation, the three blue LED indicators will blink simultaneously, indicating that it is time to clean the grease filters. To reset the filter clean timer, press and hold the OFF button for 3 seconds. The blinking LED indicators will turn off.
