Searching for help: after a power outage my two Wyze Thermostats would not power back on. The screen of thermostats remained blank.
After some troubleshooting, I discovered that the 3 Amp fuse on each HVAC air handling unit blew out. After replacing the fuse in each air handler and restoring power with the breaker on the air handler, the 3 Amp fuse blew out again.
My next step or try was to:
- remove the two Wyze Thermostats from the wall plate
- replaced the fuse a second time and
- restored power to the air handler and the fuses did not blow this time;
- I then removed the wiring on the first Wyze Thermostat mounting plate and rewired my original (non-smart) thermostat ……
…… this re-energized my original thermostat and the HVAC units begin to work as normal. I followed the same steps on the second Wyze Thermostat and my original Thermostat worked correctly.
I have not attempted to re-install the Wyze Thermostats to-date.
Can anyone help with a resolution for my Wyze Thermostats?
Thank you!
