Won't run at all.


FY4ANF048 Carrier -I came home and the unit will not turn on. I've checked the circuit breaker in garage, outside on wall and then one on the unit in closet. The thermostrat isn't even on showing nothing. It's like no power to it. It's 4 yrs old.

Is this a gas furnace? Check the fuse on the control board in the furnace if so.

No it's not a gas furnace. All electric. Del-Air told me to try these two things and I did. I went outside and used a shop vac and sucked out the water that was in the pvc pipes where the water drains from. Then at circuit breaker in garage, flip off and leave off for 30 minutes and turn back on. Did both and nothing changed. What I don't get is the thermostat isn't showing anything.

The reason they told you to vacuum the pvc line outside is it's possible you have a drain pan float safety switch would would be in the metal drain pan under the air handler. If your main drain was blocked up, the condensate water would drip into that pan and if that secondary drain line was clogged as well AND you had a drain pan float safety switch that was wired into the 24 volts or common (which powers the circuit to your digital thermostat as I'm presuming the switch may be wired to cut the 24 volts/common to stat) than the power would be cut off.

As the backed up condensate water rises in the pan, at a certain point that switch kills (by way off disconnecting electrical continuity) any power through the wire it's connected to. If that wire is the 24 volts to your stat than there you go.

Check your drain pan. Is there water in it? Is there a switch attached to the side of the pan?

Does your thermostat have batteries in it that need changed?

Thanks Marty. That happened to my home inspector to whom I made the same suggestion. Yup, bad batteries in the thermostat.

It was water in the pipe where the safety stitch was. I sucked that out and the thermostat came back on and the air cond. came right back on.
