No Power Nest E Gen 1 Error E196

docdanhl — Fri, 23 Dec 2022 19:03:58 GMT

After 2 years of normal operation, my Nest E Gen 1 gave me a message = error low power, E196. To fix temporarily I needed to remove the Y wire. This worked and now running. I need the Y wire when AC starts, what caused this after 2 years of normal function and what can be done? Battery power reads 3.88V

I just got the same message… weird. The post above was 6 hours earlier.

Thanks for the reply. I have tried the process noted in this link, and my thermostat works, but without the Y wire. I will have to do something when I need to run the AC. My question is why did this happen now after 2 years of use without a common wire?

Hi docdanhl,

Thanks for the response. You'll see this code if your air conditioner has tripped a safety cut-out switch that prevents your air conditioner from turning on in very cold weather, or your system might need maintenance.

Thanks,

Edward

Question to Jhonleanmel, how do I turn the AC switch back on when needed in the spring? Apparently this switched off and caused the power concern to the Nest.

Thanks,

Docdanhl

Hi docdanhl,

You can reach out to your AC's manufacturer as this varies per unit. You could also reach out to a pro technician so they can check your entire system and wiring to make sure everything is correctly placed.

Best,

Mel
