I woke about a month 5 weeks ago to the sound of the air handler fan trying to start. The outside fan was working, the air handler fan alone did not work but I could turn the air handler fan manually. I let it thaw out & installed a new Filtrete 1500 filter and within hours the unit was working again.
It happened again 3 days ago...I woke to the sound of the air handler fan trying to start. But this time after thawing out & installing new filter it's still not working 3 days later.
