Why is my Honeywell B/Q682 not producing heat?
- SSteven WilsonAug 18, 2025
If your Honeywell Thermostat isn't producing heat, there could be several reasons. First, check that the system switch is in the HEAT position, not OFF or COOL. Also, inspect the fuse or circuit breaker; replace the fuse or reset the breaker if necessary. Ensure the furnace power switch is set to ON, and if your furnace has a pilot light, make sure it is lit according to the manufacturer's instructions. Finally, turn off the power to the furnace and check the R and W thermostat connections, looking for correct terminal hookups, frayed or broken wires, and loose terminal screws. After addressing any issues, turn the power back on.
