Curious if anyone has had issues with the NEST Home plugin disabling your air handler's fan.
I installed the plugin for the first time over the weekend. Installation was smooth sailing. The plugin immediately recognized all of my NEST devices. At that point I didn't bother creating any rules with intention of coming back to it the next day.
The next morning I woke up to a warm house. No air flowing through the vents. I checked the air handler. It was on but frozen over. I could hear freon moving through the system but the fan was not running. I manually turned the fan on through NEST, still no luck. At this point I realized that the plugin could be causing an issue.
I disabled the plugin and turned off my HVAC system so that the air handler could thaw out. Once thawed and with the NEST plugin disabled, I turned the system back on and the fan immediately began running. I haven't had any issues since disabling the plugin 3 days ago.
The HVAC is a new Lennox heat pump system that was installed less than a year ago. I had the HVAC repair company come out to take a look and they reported that the system was operating perfectly. No issues at all.
My money is on the NEST Home plugin since that's the only variable that changed. Has anyone experienced anything similar? Any thoughts?
