E 183 Error

[Jade122333]

I had a power outage last night for about 4ish hours until about 2am. Once the power came back all, everything was fine. Around 6pm the same day, the thermostat gave a E 183: problem with the Y1 wire. I checked all the wires and everything seems to be set up correctly. Even the thermostat states everything is wired correctly, yet the system wont blow cold air for longer than 30 seconds before shutting off again.

The E183 error means there is an overcurrent detected on the Y1 terminal.

Swap the Y1 and G wires and see if the error code is for a problem on the G wire. If the error change changes, then you have a problem with your system.

Thank you so much!!! 2 follow up questions

1. What do you mean by system? (Are you referring to the entire wiring or nest thermostat) and 

2. If the error stays the same (on the Y1), what does that mean?

[Patrick_Caezza]

By system, I mean the HVAC equipment

If you swap the Y1 and G wires and you still receive the E183 error then the Nest probably has a problem.

@Jade122333, how's it going with your Nest Thermostat? Still need our help?

Thanks,

Turns out it was some sort of internal wiring issue that caused a short. Thank you everyone!
