Error E103 1Y

Emmanuel813 — Thu, 07 Apr 2022 01:10:55 GMT

After 7 months in our new home and positive feedback about our nest thermostat just out of nowhere I come home “FL” and ac is not working. The inside unit kicks In for like 5-10 seconds then shuts down. Outside unit not turning on. I check wires. Ac connections and nothing. Error E103/problem with Y1 wire. Helpppp. I try switching out the cable with a non use one from thermostat to inside unit to outside and nothing. What can it be.

The E103 error means there is an overcurrent condition on the Y1 terminal and your system might need to be serviced.

He is a link to a better explination.
