This 03501041 replacement is designed for specific legacy wall-mounted thermostats. Always verify your specific model number on the control board or housing before installation. How do I remove the old knob without damaging the shaft? Ensure the system is powered down, then apply steady, even outward pressure. If the knob is stuck, a plastic prying tool can be used to avoid marring the thermostat faceplate. Can this be used for air conditioner control panels? While primarily a thermostat knob, it is used across several equipment lines; however, checking the shaft depth and diameter is essential for cross-compatibility.
