    Why White Rodgers Furnace Cycles Too Fast or Too Slow Cooling Cycles Too Fast or Too Slow?
    • M
      Michele HansonSep 7, 2025
      If your White Rodgers thermostat has furnace cycles that are too fast or too slow, or if the cooling cycles are too fast or too slow, the location of the thermostat and/or the size of the Heating or Cooling System may be influencing the cycle rate. Item 4 (CR Heat) or 5 (CR Cool) in the Configuration Menu is the adjustment that controls the cycle rate. If an acceptable cycle rate is not achieved using the FA (Fast) or SL (Slow) adjustment contact a local service person for additional suggestions.
