Device detection has detected my furnace fan within a few days of installing the device, which is supposed to rotate air 10 min/hr or open a damper (to allow for ventilation) and then run the fan. So in total the fan would run ~ 2-4 hours a day.
Because of excess moisture in the air inside ( outside its > 75% humidity), I had turned off ventilation for a few days now ( have 2 kids that open the door all day long so we have good air quality) and may have turned off the circulation fan too.
Sense App was able to show that the run time in the last 2 weeks was down significantly.
Earlier the Air Conditioner used 5KW, now the AC and a newly discovered Motor combined use about 5 KW. However, when the AC turns ON the furnace fan isn’t turning ON, and the AC shuts off in ~ 30 seconds ( guessing some form of safety mechanism).
I tried to just turn on the FAN, and the Ventilation, and also the heat and see that the furnace fan really doesn’t kick in for the whole period of time. So it’s either the capacitor or the furnace fan.
This Sunday we are expecting 95 F weather, which is atypical in Seattle area, and so I need to get a handle on this before that.
