Heat or Air won't turn off from Thermostat


what I meant by 'programming' was after wiring the new thermostat did you have to internally program ( run thru menus etc) for the type of system you have (heat pump) and if the reversing valve is energized in cooling or heating. I was just curious on this as they can be confusing at times.

good luck and let us know how it comes out

one last ? when it says on and runs and runs (if you remember or if it happens again) is the air coming out of the reigsters, say in your room, hot/very warm or just room temperature-ish. that says a lot

If you have a heat pump with electric aux heat. unless you can lock out the aux heat, you should not be setting the temp back, as it can cause you to have a higher heating bill then you should.

Heat or Air won't turn off from Thermostat


Every since the heat went off two days ago I haven't been able to get it to come back on. So far I've tried the new t-stat and the old. Whether I turn it to Heat, Cool, or fan nothing happens and it's a simple wiring setup. I wonder if a fuse has blown? Any ideas would be most helpful? The last time the unit was on it shut off by itself. I really don't think me lowering the heat had anything to do with it turning off.

at the tstat. Touch green and red bare wires together. No fan still? nada zip, nil???

Reset breakers on Air handler. do it again - still nada??

Open air handler look for 5a fuse if you wanna go down that road

Best case blown fuse - worst xfmr popped

all of this after you are sure you have eliminated wiring at t-stat, temp control, programming etc.

good luck

I like the $220 hex

Thanks for the info. I checked the red and green connection and nothing happened. I will check the air handler next. I know there is a circuit box (gray box w/ a black plug at the top) about 10 feet from the air handler. Is this the breaker you're referring to or is there another breaker on the air handler itself? I appreciate your expertise.

By touching the red and green you are just trying to confirm that you have 24volts still coming in to the thermostat, basically 'hot-wiring' your fan. You said nothing happened so that would take you next...

I was thinking of the main breaker at the box for the air handler - reset

longshot but try the red and green again together...

then if nothing:

The fuse I was refering to is (typically) in the air handler along with the transformer. If you are brave enough to dive in and look, this is where you will find the the suspects.

Thanks. I'll look in the Air Handler tomorrow. I will just make sure the circuit breaker is off. I'll keep you updated. I'm hoping it's the 5a fuse. Luckily, it will be 78 degrees here tomorrow.

5amp fuse was blown in air handler. Replaced the fuse and unit and red to green kicks fan on. Hopefully, all will be fine when t-stat is installed. Thanks for all the help.

did you get it working correctly? typically the carrier/honeywell comination if you purchased a heat pump t-stat would be red to Rc jumpered to Rh green to G terminal(fan) orange to O/B (reversing valve) white to W2/aux jumpered to E emergency heat (heat strips) yellow to y/y2 (cooling) blue to C (common) this wiring is at the t-stat but could vary slightly with how the air handler and condenser wires are wired. so first check the colors that are wired to the condenser then the check that they match the wiring in the air handler then the t-stat

Looks like I spoke prematurely. I haven't confirmed it yet, but I think the fuse blew again. I say this because I installed the t-stat and nothing turns on.
I removed the t-stat and tried the GREEN to RED wire test again and this time no success. I will check the new fuse to confirmed that it's the problem,
but my guess it that it is. If the fuse has blown again is there something else I should check?

Thanks
