Nest thermostat error code e183

JoshA1 — Tue, 20 Jun 2023 04:02:58 GMT

Hi folks,

I have error code e183, and I'm trying to determine my next steps. Here's some info:

I have Nest Thermostat E.
I swapped wires Y1 and G, and the error changed to e184, indicating a problem with the G wire.
That indicates to me that the issue is not with the Nest, but with the power current of the Y1 wire.
I reset the breakers for the AC, but am still having the error.
Temporarily I've disconnected the Y1 wire from the thermostat so I can skip the error and run the fan all night. Obviously, this provides no cooling and is not a real solution.

What are my next steps for troubleshooting? I have an HVAC professional coming over in a couple days, and he should be able to help. However, I'd like to try to resolve this for free or cheap if it's something I can handle. Any ideas?

@Patrick_Caezza I saw you answering questions similar to this, so maybe you have some ideas? Thanks in advance!

Hi JoshA1,

Thanks for reaching out to us, and I'm sorry to hear about the situation. Let's sort this out.

The E183 error means that there is an overcurrent error on the thermostat, indicating that the electrical current on the thermostat wires connected to the Nest Thermostat has spiked multiple times, causing the internal breakers of the thermostat to activate in order to protect the thermostat base plate and system components from damage. In this case, I highly suggest you remove the Y1 wire for the meantime, wrap it with electrical tape, or tuck it inside the hole on the wall where it won't touch other thermostat wires while we wait for the HVAC technician to to come to your home.

I understand that you want to check other ways of resolving this situation, but only an HVAC technician can check on this for your safety, as without protection, overcurrent can damage electronic equipment and cause electrical fires, shocks, and electrocution if not handled properly.

Let us know if you have any other questions. We're happy to help.

Best,

Zoe

Hi Zoe,

Thanks for getting back to me. The HVAC tech said that any voltage over 27 would cause the issue. My two options were either some complex wiring things to reduce the voltage, or to change to a different thermostat. I changed.

Thanks again,

Josh
