Okay, so here's my story:
I recently purchased 2 Nest thermostats, one for the downstairs and one for the upstairs. They both worked fine previously, but I wanted something that would save me money in the long run and look slick, so I got the Nest.
Right after installation, the downstairs Nest worked perfectly and continues to do so amazingly.
The issue is with the upstairs Nest. The first week it ran fine, but then after that it would turn off and say there's no power going into the Rc port. I installed both Nests the same way and there was no issues with the old thermostat upstairs. Now I did change the fuse to make sure that wasn't the problem...and I thought it was, because it started working again! But after a couple of days...same Rc no power issue. So I changed the fuse again...powering off the main switch to make sure I dont get shocked...and it went back on again!!! I had thought I had fixed it, but nope. A couple of days later it turned off again with the same Nest error e32 or something (no power to Rc).
Does anyone have any recommendations before I call the professionals? It's the the Nest that's having issues because I switched with the dowstairs Nest and it had the same problem upstairs. It's gotta be something with the upstairs HVAC...maybe wiring issues? Not sure.
