Everything worked and then my ducts were cleaned by a company, all of the sudden thermostat display on the wall is off. The app says “no wifi”, yet my cameras work. Did a router reset just in case, the display is still off, as if it is not connected properly.
The A/C breaker is on, the furnace switch is ON.
Is it possible they pulled the thermostat cover and then broke connection by bending some of the male pins on it? I opened the plate to investigate and the male pins in the bottom row were wobbly and bent a bit. Then this person blamed ME for breaking it and would not listen that the thermostat was OFF before I even touched it. Maybe they took the mounting plate off and put it on with force? Or what else got disconnected during this cleaning?
How to fix it?
