Cant get AC to work with thermostat

Home

I have checked my wiring and looked at just about everything i think. Thermostat will not kick AC on. Does anyone have any ideas?

Not an HVAC Guy and @speadie may chime in as well. :slight_smile:

However, couple of questions:

  1. Can you post a picture of your HVAC system as well - where the wires connect
  2. Did you use the Power Adapter? you need to have a common on the Wyze T-Stat and since your image does not appear to have a C wire connected, you will need to use the Provided Adapter
  3. Can you post a picture on how you had the Wyze T-Stat connected as well? if you have a picture of it

I was thinking the same thing, without a C wire or the adapter, the thermostat might not have enough consistent power to properly trigger the AC. Curious to see the wiring pics too, sometimes it’s just a small thing that gets overlooked!
