I had a new Thermal Zone furnace put in last winter. It’s been working fine since. The AC was also working fine through the summer so far until a couple of days ago. The compressor fan tried to run, but the blower fan in the basement doesn’t.
I turned it off over night, and tried to start it up yesterday morning. The blower fan kicked on for a minute, and I had cool air from the vents. But then it turned off again and hasn’t started again since.

The air filter was wet with condensation, so I took that out as a trial. That didn’t help. I put new batteries in the thermostat, and that didn’t change anything. There are no blown fuses that I can see. It’s a brand new unit, so I wouldn’t expect a bad capacitor or worn out ball bearings.
Any thoughts?

 

My first thought is that it's under warranty. Call for warranty service.

Posting a model number of the air handler would be helpful.

 

Being brand new it very well could not have a capacitor for the blower.
As said above, it’s likely under warranty. Let the installer worry about it.

 

The AC unit is much older than the new furnace, so I’m not certain about whether it would be under warranty. The model number is TZ92MSP100C50A.

 

Blower is part of the furnace.
If your leaking water into the furnace, that can cause very expensive damage to the electronics that will not be under warranty.

 

I’ve also just noticed that when I first try to turn it on, there are red light numbers that flash on the bottom of the furnace/blower fan control panel in this sequence... 262626585920, and then a final constant 0.
