I could use any help that I can get. The only way that my air will come on is if I cut on the heating on the fusebox panel, and then the heat and the air will come on. I put in a new thermostat but the only way that anything will work is if I cut on the heat. With the air fuse on it does not work. I would appreciate any help.

The thermostat controls heat, cool and fan(s), misswiring can cause it to try and heat and cool at the same time.
Would check thermostat wiring?

Did you put a jumper from rh top rc when wiring the new stat??

No, I didn't put a jumper, I just reconnected it the same way it was-should I do something different?

Were you having this problem before you replaced the thermostat? If not, perhaps the new thermostat is configured or intended for a heat pump system.

Yes, I was having this problem before I changed thermostats- I just checked the wires(4) and they are all in the right place. The new thermostat works perfectly now, it's just when I cut the air off on it the heat still stays on. And the only way all of it stays on is if I flip the heat fuse on the fusebox.

I looked at the wires to see if I could disconnect the one that controls the heat, but that didn't work either. It seems no matter what I do, the heat just won't go off unless I cut it all off at the fusebox. It's supposed to reach 100 degrees tomorrow so I sure could use some input! Thanks!:)

Is this a electric furnace? Probably need a new heat sequencer.

Yes sir, it's an electric furnace. What's a heat sequencer?

Controls the fan and the heat on your furnace, probably stuck causing the heat and the fan to stay on.

Good call. Definitely fits the profile.
