Customer Question

I have a mountain air energy star made by Honeywell that currently is not getting power to the thermostat but has power going to it
JA: Did you double-check the thermostat's settings? And what about the filters?
Customer: I tried to replace it with a nest thermostat but they told me it wasn't getting 24 volts so I needed to hook up my old one back up and I did but the face of the thermostat is not lighting up
JA: Do you plan on doing the work yourself?
Customer: Yes
JA: Anything else we should know to help you best?
Customer: no

Hello if you can send me a photo of the thermostat wire connections on the existing thermostat I will mark it up with wiring instructions..

Use the 'add files' link next to your send button for that..

We can go from there
