This is a communicating thermostat. No batteries. If the display is going blank, either the furnace or air handler this connects to is have a power issue OR the thermostat itself is bad.
Customer: replied 6 months ago.
So what should I do?
Expert:  Tim H. replied 6 months ago.
What does this connect to?
Customer: replied 6 months ago.
those prongs go into those holes.
Expert:  Tim H. replied 6 months ago.
No, that's not what I mean. I mean does this connect to a gas forced air furnace? An air handler? What?
Customer: replied 6 months ago.
I mean it's a central air system if that's wat u mean...
Expert:  Tim H. replied 6 months ago.
I understand that. But in your basement or your attic, wherever the unit that blows air through the house is. What kind of unit is it? A gas furnace will have gas piping. An air handler, no gas piping.
Customer: replied 6 months ago.
Are you talking about the heat pump?
Expert:  Tim H. replied 6 months ago.
Since this problem could be caused by your furnace or air handler, next time it happens, take the front section off the wall and with a voltmeter set to "volts AC", test from the C to the D terminal at the stat. We should see 24 volts. If not, then your furnace or air handler is bad. If there is 24 volts and no display, the thermostat is bad. If you are not able to perform these tests that's OK, Since it's only a year old, the unit is covered under warranty. Then it would be best to contact your local HVAC service shop.

I have to step away for a short while, but can answer any other questions you have when I get back.
Expert:  Tim H. replied 6 months ago.
Let me know if you have additional questions.
Customer: replied 6 months ago.
So I called around and the closest HVAC shop is three hours away and they only travel about an hour out
Expert:  Tim H. replied 6 months ago.
We could troubleshoot further, but you would need a voltmeter. And even if we found the problem, you would need parts. Let me know.
Customer: replied 6 months ago.
Well I probably wouldn't be able to get one until Saturday is that too long to wait?
Expert:  Tim H. replied 6 months ago.
No, question will remain open.
Customer: replied 6 months ago.
Thanks!
Expert:  Tim H. replied 6 months ago.
OK
Customer: replied 6 months ago.
Ok thanks for waiting! So I just tested it and I'm getting 27.0 volts
Customer: replied 6 months ago.
So where should I go to get a new thermostat?
Expert:  Tim H. replied 6 months ago.
Your best bet is online since local Carrier dealers will probably not sell to you. If you enter that model number into a search engine, it should bring up many sites that sell this and then you can compare prices.
Customer: replied 6 months ago.
Isn't it still under warranty?
Expert:  Tim H. replied 6 months ago.
If you are going to try and get it covered under warranty, you will need to go through your local Carrier dealer. They are the only ones that can turn it in for warranty replacement.
