“What do you do when the thermostat display goes dark and the A/C turns off? Wiring looks ok and drain is not flooded.”

• Hi, thank you for your question. Please make sure that all wires are firm and secure inside the wiring terminals, reset your circuit breakers and make sure that there is no open door/panel at the furnace/air handler, specially if you recently replaced the filter. If you have already verified this and the situation persists, the thermostat might not be receiving power from your HVAC system. Check the AC voltage between the R and C wires on the thermostat side. The voltage should be between 20-30 VAC. If the voltage is not within that range, please contact your HVAC contractor to take a look at that. If the voltage is fine you will have to replace the thermostat, this model has 1 year of warranty through the place of purchase. - Maria
