If your Honeywell Thermostat display isn't turning on, make sure the batteries are correctly installed and fresh. Also, ensure the thermostat is properly mounted and latched onto the wallplate.
Why is my Honeywell 36 heating not working?
If your Honeywell Thermostat isn't heating, ensure the heat setting is higher than the room temperature. Also, check if the circuit breaker has tripped and reset it if needed. Verify the system switch at the equipment is in the On position. Allow five minutes for the system to respond. Finally, confirm the system switch is set to Heat.
Why is my Honeywell 36 Thermostat cooling not turning on?
If your Honeywell Thermostat cooling isn't working, make sure the cool setting is lower than the room temperature. Check the circuit breaker and reset it if necessary. Ensure the system switch at the equipment is in the On position. Give the system five minutes to respond. Lastly, ensure the system switch is set to Cool.
Why does my Honeywell 36 Thermostat display flash when programming?
If your Honeywell Thermostat display flashes during programming, it means you've reached the temperature setting limit. The heating range is 40°F to 90°F (4.5°C to 32°C), and the cooling range is 45°F to 99°F (7°C to 35°C).
Why does my Honeywell 36 change temperature at the wrong times?
If your Honeywell Thermostat temperature changes occur at the wrong times, check the program times for the affected period, ensuring AM and PM settings are correct. Verify the current day and time are accurate. Reprogram if needed. If the thermostat is set for Smart Response, start times may occur before your programmed comfort periods.
What to do if Honeywell Thermostat shows heat or cool but no air is coming out?
If the system on indicator (flame or snowflake) is lit on your Honeywell Thermostat, but you're not getting warm or cool air, wait five minutes after the indicator appears before checking the registers. If there's still no air, refer to the "Heating will not come on" or "Cooling will not come on" troubleshooting steps.
