Nest thermostat delayed; has c wire and good voltage

[JillK]

I have a 3rd gen nest thermostat. Last night it started delaying for 3 minutes several times. It has a c wire and the voltage is 3.93. It’s always worked fine until last night. What’s going on?

Possibly loose connections at equipment

Hi folks,

@JillK, thanks for posting here in the Community forum, and I'm sorry to hear about the situation. Let me take a look at this for you.

Please gather your Nest Learning Thermostat's power readings under Settings > Technical Info > Power (Battery, VOC, VIN, and lIN). 

I'll look forward to your response. 

I appreciate your help, @HVAC. 

Best,

Zoe
