My nest gen 3 stopped turning on the outside unit. It worked fine for a week the stopped turning on the outside unit. Did a lot of troubleshooting eventually changed out the thermostat with an Eccobee, that too work one week then stopped again. I have to "hotwire" the wires for it to work. HELP!! I'm about ready to beat this thing with a sledge hammer!!
HotinTx, I wanted to make sure you've got Patrick's response above. If you still need help, please provide the requested photo so we could take a closer look.
Problem is not fixed. I don't think it's a wiring issue though. Our nest just stopped working one day got a new one hooked up the same as b4 stopped working a wk later. Ac tech told me the other day that it may be the unit itself...so I dunno
I understand where you're coming from. However, having two thermostats fail on the same system after working for quite some time is uncommon. It is best to start checking on the wires or have a local HVAC technician check on your HVAC system to cover all the bases.
We haven't heard from you in a while so we'll be locking this thread if there is no update within the day. If you have any new issues, updates or just a discussion topic, feel free to start a new thread in the community.
