Air Conditioner troubleshoot

Hi All,

I have an ecobee lite 3 thermostat that was installed a few years ago. I noticed when I set my AC temperature to (whether it's 0.5 degrees or 4 degrees) below my house temperature, the AC unit doesn't always run. I am able to turn the fan on and off though.

I also turned off the ecobee+, but doesn't make a difference. The AC unit will sometimes respond, but not always.

Any idea how to troubleshoot this?

If jumping RC+Y turns the AC ON immediately than its a indication that your tstat has a issue. If only jumping the wires at the board level gives you the desired results than its the wiring or tstat issue.

Is this through your phone or at the Ecobee itself? I notice there is a little lag changing the temp on your phone. It happens, just not as instantaneously. At the ecobee itself, my AC runs right away.
