Customer Question

My Fujitsu mini-split unit is flashing the "operation" and "timer" lights simultaneously 5X, then the timer light alone 1X. I've tried canceling the timer (though as far as I know it's never been set) and turning the unit on and off...that's about the extent of my expertise. It's -20C here, but it's worked in colder weather. Please help!
