Yet Another AC Help Thread

Lost power at my Tstat last night. Tstat does not have batteries and no breakers are flipped. Mulitmeter shows I am not getting any power to my Tstat. In air handler, fuse on circuit board ohms out good. I have 240 coming into the transformer, and 24 coming out.
I figured the most obvious answer is there is likely a flipped breaker somewhere, but the air handler doesnt have a breaker, or atleast a visible one. And no other breakers in any of my fuse panels are flipped.
Air Handler
Any thoughts? Thanks fella

Check the switch in your water pan. I think sometimes it kills power to the board which is sending power to your thermostat.

Double check fuses and relays. There is likely more than the one you checked and verified as good. You should be able to get a wiring diagram of the air handler on line that you posted if you don’t have one in your files that would show this. You seem handy, so you might be locate any others from a wiring diagram.
