Brand Heritage: Sears/Kenmore thermostats were manufactured by White-Rodgers, a division of Emerson Electric. White-Rodgers has been producing quality HVAC controls since 1906 and is one of the most trusted names in the industry.

This is an older-style mechanical thermostat from when Sears was a major appliance retailer. While functional and reliable, it also represents a piece of American home comfort history. Perfect for those maintaining period-correct homes or who prefer vintage mechanical controls.

Q: Will this work with my heat pump?
A: Yes, but ONLY for single-stage heat pumps WITHOUT auxiliary/emergency heat. If your system requires E or AUX heat terminals, you need a different thermostat.

Q: Can I use this with my programmable schedule?
A: No, this is a non-programmable thermostat. You manually adjust the temperature as needed.

Q: What if I have a 2-stage furnace or AC?
A: This thermostat is for single-stage systems only. Multi-stage systems require a different model.

Q: Will this fit where my old thermostat was mounted?
A: Very likely yes! White-Rodgers mechanical thermostats have used the same footprint for decades, so wall marks usually aren't a problem.

Q: Does it work with baseboard heaters?
A: No, baseboard heaters typically use line voltage (110V-240V). This thermostat is for low voltage (24V) systems only.
