I own a Goodman ARUF049-00A-1B air handler which I've started having problems with this week.
A couple nights ago, I awoke to the smell of something burning through the A/C vents. I noticed that the airhandler was not blowing even though the compressor outside was on. I turned off the A/C at that point to be on the safe side.
The next day, I turned it back on. I could hear the compressor turn on outside. This time, the blower turn on as well. However, after about a minute, I started hearing a rhythmic whining sound coming from the air handler. The whining subsided...but I also noticed the fan began to slow down. After about 5 minutes the fan had come to a full stop even though the thermostat had not reached the temperature I set. I shut off the A/C and a few seconds later, the "burn smell" came through the vents again.
Does anyone know what it most-likely could be? The unit is about 7yrs old.
