The blowers fan in my condo is running more often than not. The fan is not scheduled to run at all, yet runs majority of the time (75% of the day).
The company who installed the blower has been out twice and is sure its an issue with the Wyze thermostat. Can anyone please provide some help 
It may take some more information to see what is going on.
Do you have a C Wire Adapter installed?
Can you provide a pic of the control board wiring where the thermostat wires connect? What about a pic of the old thermostat wiring before the install?
Unfortunately I do not have a picture of the old wiring as I no longer have that thermostat. I’m in a condo and have a heat pump. I will do my best to grt some pictures of the wiring to it today .
I tried to access the control board to see the wiring but have not been able to access it as it’s built into the ceiling. I tried to access it without luck.
You mentioned that the company that installed the blower fan had been out… Did this start with the installation of the fan or the thermostat?
I think the wiring on the other end is going to be the important pic to get to see how those are wired. @speadie is the go to user when dealing w\ HVAC wiring. I will let them post in with any other possible ideas.
I really can’t get to it. I jusy broke my dryer getting into the ceiling trying to gain access 
If it is in the ceiling, it is most likely accessible from an attic service access. No need to break a neck to get to it right now. Might just wait and see what other posts come in.
I’m in a condo, above me is another unit sadly.
Hmm. Without visibility on the other side of the wiring, I can walk you through some troubleshooting steps, but if it’s wired the way I think it might be, fan access would be critical to actually get it working.
First, I want you to remove the green wire and see if the fan stops running - note you will need to hook it back up, this is just a temporary test to see if any other wire is carrying the fan signal. Let me know if the fan still runs with the green wire not connected to the thermostat.
I have removed the green wire and it continues to run.
That means that some other wire is driving the fan,. There’s not much you can do without fan/furnace side access to the wires other than install the old thermostat, unfortunately.
What confuses me is it’s so Intermittent. It runs and then it doesn’t. It’s just so frustrating.
