  If your White Rodgers Thermostat is not cooling, make sure the SYSTEM switch is set to COOL and the setpoint temperature is lower than the room temperature. Verify that all thermostat and system wires are securely attached. If the issue persists, the cooling system may require professional service or the thermostat may need replacement. Try setting the thermostat to COOL and lowering the setpoint below the room temperature as a diagnostic step.

  If your White Rodgers Thermostat is not heating, first check if the pilot light is lit and re-light it if necessary. Ensure that the SYSTEM switch is set to HEAT, and the setpoint temperature is above room temperature. Verify that all thermostat and system wires are securely attached. If the heat works intermittently, it might be a furnace lock-out condition, and you should contact the furnace manufacturer or a local service person. If the thermostat doesn't click after being reset, contact your heating and cooling service person or place of purchase for a replacement.

  If your White Rodgers Thermostat has a blank display or the keypad is not responding, a voltage spike or static discharge may have occurred. Use the Reset Operation. If that doesn't work, replace the batteries and check the heat/cool system for proper operation.
