I’m trying to find out if my thermostat is the issue with my A/C turning off on its own. When the A/C attempts to cool, it will stop in about 15-30 mins and will have a message on the thermostat that says “Protect”. I also see other messages on the thermostat such as, “AC Power Lost”, and “No Wiring Detected”. I did go into the wiring menu and confirmed that the thermostat had the correct configuration so I’m not sure why it gave the wiring error.
I also replaced the AAA batteries in the unit but haven’t had any luck resolving this.
I will have some AC repair folks to inspect our AC, but I wanted to get more information about the thermostat issues so their visit would be more effective.
Please let me know if you have any questions
