Why won't the heating respond on my White-Rodgers 1F85CA-0471 Blue thermostat?
Set SYSTEM to HEAT, raise the setpoint above room temperature, and listen for a soft click within seconds.

- No click after reset means the thermostat likely needs replacement
- Check that the pilot light is lit
- Verify furnace power switch is ON and blower compartment door is properly installed Instruction Manual, p. 9
