What to do if my White Rodgers UP300 has no heat, cool, or fan?

If your White Rodgers Thermostat isn't producing heat, cool air, or running the fan, consider these potential causes and solutions: * Check for a blown fuse or tripped circuit breaker; replace the fuse or reset the breaker if necessary. * Ensure the furnace power switch is turned ON. * Verify the furnace blower compartment door or panel is correctly installed to engage the safety interlock or door switch. * Inspect for loose connections to the thermostat or system and tighten them. * Replace low batteries.
