Should your HVAC system cease to function during periods of intense heat or severe cold, there's a potential you could experience a considerable amount of discomfort.

Don't worry because, in this guide, I’ve provided step-by-step instructions on how you can reset your White Rodgers thermostat to get your heating and cooling back up and running, so keep reading on!

Before you remove the thermostat from its base plate, as directed in the instructions, make sure to isolate the circuit to avoid exposure to live wiring.

Also, I always advise readers not to tackle any DIY or electrical tasks they are not skilled in carrying out, and if in any doubt, it’s best to get the help of a professional.

White Rodgers Thermostat: Find Your Thermostat Model First

The reset instructions can vary between each thermostat model. So to make sure you don’t make any mistakes and get the most accurate instructions, it’s better to know the specific model number of your thermostat.

  • Usually, the model number is printed on the back of the thermostat cover plate. So to find the model number you will have to remove the cover plate or pull the thermostat out from the wall mount.
  • Be careful when doing so as the thermostat wiring may be exposed when you remove the cover plate/thermostat display.
  • Besides that, you can also check the user manuals or any documentation that came with your thermostat to find your model number.
  • However, if you can’t find the exact model number, we have included images of each thermostat below to help guide you.

    HELP! I have a 1f88-385 white Rodgers thermostat that is stuck on hold (after company starting messing with it). Also I can’t adjust the time and figure out how to set it foe different times of day. Also I need a manual for this particular model so I can learn to program it.

    Is this an older model?

      Hi Leslie,

      The reset operation for the 1F85-275 is similar to the others listed. You isolate the circuit, remove the wires from the R and C terminals and remove the batteries for 2 minutes. (Sometimes it is recommended to leave it longer or put the batteries in reverse for 10 seconds to ensure the power is fully drained from the device). Then put the batteries in correctly again, put the wires back in to the terminals, remount the thermostat and enable the circuit again. That should reset the device.

      If the display is still blank then time to call in the pros!

      Hope this helps
