I am having problems with my central heat. When I turn it on and let it run it continues to only blow cool air. When I turn on the emergency heat the air comming out of the vents only gets a little bit warmer. Also I keep reading that the big line is supposed to be warm to the touch but mine is cool as well? Its a trane setup. Outside unit is "High efficiency weathertron heat pump XE1100" inside unit model number is TWG042A140A0. I am pretty sure the T stat is working properly because i can hear the unit make a noise when i put it to emergency heat? Any help or suggestions as to what could be wrong would be great. Thanks.

Check the circuit breakers OR fuses on the outside unit. Check the circuit breakers on the main panel.

Sounds to me like you have a problem with the outside unit. Check all low voltage wires going to the unit for damage.

The inside emergency heat is eigther to small or some of the heat strips are not working. You should probably check those also.

If you are not experienced in electric and do not have a meter I suggest calling for professional service before you freeze because during this time of the year the HVAC companies could be back logged.

I dont know a whole lot about the a/c units just enough to get me in trouble. Electric work isnt a prob. When the air conditioner was on prob about a month ago the outside unit was working? or is it a whole different aspect of the unit that may be wrong with the heat side?

One more thing. Is the outside unit supposed to come on in heat mode? reason im asking is because i have never payed attention to whether it does or not and at the moment it isnt? Just curious. Thanks

Heat pump is supposed to run in the winter.

So that would be a reason as to why I have very little heat? Because the outside unit is not running at all.

Yes

Ok guess ill have to take it from there. All elec. is good. It may be something to do with the thermostat then i guess everything else including a/c has worked fine with it tho. I'll tinker around and see if i can figure out if i wired it wrong when i put it in. Sorry for being an idiot at this subject but thanks for the help.

Ok. I have come to the conclusion that i have miswired my t-stat in some way and maybe you or someone can help me. worth a try i guess as to what each of the wires may go to not how they connect up on the tstat i can figure that part out. here goes. in my inside unit i have 6 wires for the unit (3 white, 1green, 1 blue, 1red) tstat wires(white, green, blue, red, black, orange, yellow, brown) inside tstat wires that loop directly to outside tstat wires (orange, yellow, brown) Both inside and outside white tstat wires conect to all three white wires comming from unit. Both reds connect to red coming from unit. boh blues connect to blue wire coming from unit. only outside green is connected to green coming from unit. both black wires and inside green wire are not used or connected to anything. thanks for the help if possible

messed up. actually its only inside tstat green is connected to green coming from inside unit. not the outside tstat. iunderstand that the green is for the fan. the red is the 24v. power. the rest im clueless on.
