If the Honeywell Thermostat display is blank, first check the circuit breaker and reset it if needed. Ensure that the power switch for the heating and cooling system is turned on and that the furnace door is securely closed. Also, make sure that fresh AA alkaline batteries are correctly installed.
What to do if my Honeywell Thermostat heating or cooling system does not respond?
If your Honeywell Thermostat's heating or cooling system isn't responding, try the following: * Press the Mode button to set the system to Heat or Cool, depending on your needs. * Ensure the desired temperature is set higher than the inside temperature when heating, or lower than the inside temperature when cooling. * Wait 5 minutes to allow the system to respond.
Why is “Cool On” or “Heat On” flashing on my Honeywell resideo TH6320U2008?
If the “Cool On” or “Heat On” message is flashing on your Honeywell Thermostat, this indicates that the compressor protection feature is active. Wait 5 minutes to allow the system to restart safely, which prevents damage to the compressor.
