Occasionally there may be times when you need to reset your home thermostat. For example, if you crank up your heat setting but your furnace doesn’t seem to respond, you may need to reset your thermostat. Or maybe your 5-year-old stood on a chair and happily mashed buttons on your thermostat so much that it caused an error. Whatever the case, the type of thermostat you have will determine how you should reset it.
Let’s go over some common thermostat issues, including when and how to reset your thermostat. However, if you follow these instructions and your home still doesn’t reach the set heat/coolness of your thermostat, it may be time to get a professional to take a look. Call us anytime for thermostat help and all professional HVAC repair in Las Vegas.
The Most Common Thermostat Issues
There are a variety of possible thermostat problems that may be resolved by resetting your thermostat.
But before you read how to reset your thermostat, remember that doing so will put it back to its factory settings. If you’ve set up any programs or schedules, you’ll need to set them up again after the reset.
Here are some of the most common thermostat problems:
- Incorrect temperature reading: A reset can recalibrate the temperature sensor if your thermostat is reading the wrong temperature.
- HVAC system not turning on: A reset can reboot the system and restart normal functioning.
- HVAC system cycling irregularly: A reset can restore proper cycle times and durations if your system turns on and off frequently or at odd intervals.
- Thermostat resetting itself: A reset can help if your thermostat is resetting itself due to old batteries, power outages, or other issues.
There are also some problems that a thermostat reset will likely not fix. In this case, you may need to reprogram, repair, or replace your thermostat. If needed, a Sunrise Service technician can help you.
- Faulty thermostat: A faulty thermostat may have a blank screen, or it may not show the correct temperature.
- Faulty wiring: Loose or damaged wiring can interfere with the thermostat’s functionality.
- Dirty thermostat: Dust can accumulate between the electrical contacts inside the thermostat, causing inaccurate readings.
- Miscalibrated thermostat: The internal factory calibration settings of the internal sensors may become less efficient, causing improper readings.
- Incorrect thermostat placement: The thermostat may be placed near a bright window or door, making it difficult to accurately read the home’s temperature.
- Thermostat programmed wrong: A smart or programmable thermostat may be programmed to the wrong setting
- Self-tripped reset button: If the thermostat’s reset button is tripped but you did not do it (it seems to have “tripped itself”) an internal electrical issue is probably to blame.
How to Reset Your Digital Thermostat
How to Reset Thermostat with the Reset Button
If your thermostat has a reset button, you can try these steps:
- Turn off the HVAC system
- Remove the thermostat cover
- Find the reset button, which is usually small and recessed
- Press and hold the reset button for 5–10 seconds
- Wait for the thermostat to reboot and the display to turn back on
How to Reset Thermostat By Turning Off the Power (No Reset Button)
If your thermostat doesn’t have a reset button, you can try turning off the power to the thermostat:
- Turn the thermostat to the off position
- Locate the circuit breaker for your HVAC system
- Turn off the breaker
- Wait 30 seconds
- Turn the breaker back on
- Turn the thermostat back on
How to Reset Thermostat by Removing the Batteries
If your thermostat uses batteries, you can try removing them for a short time. Believe it or not, this can help reset some thermostats.
- Install the batteries backward
- Wait 5 seconds
- Reinstall the batteries properly
If you need more specific instructions for resetting the heat on your exact thermostat model, you can find their user manuals online. Search Google for “user manual” + make and model of your thermostat. We’ve even taken the first step for you—click the links below to access manuals for some of the most common thermostat brands:

Resetting your thermostat can help fix issues like being stuck in heating or cooling mode, resolve stuck programming, or connection issues. However, avoid resetting your thermostat too often because it can cause your thermostat to break down faster.
How to Reset Your Furnace
If you’ve tried resetting your thermostat and your home still doesn’t have heat, the issue may lie with the furnace and not the thermostat. Follow these steps to reset your furnace.
- For oil or gas furnaces, first check to ensure there is enough fuel inside your furnace.
- Turn down the thermostat to its lowest setting to bring the furnace down
- Kill power to the furnace by pulling its fuse or flipping the related circuit breaker
- For gas furnaces, turn off the main gas supply but leave the pilot gas supply one. Then re-ignite the pilot flame with the help of a match or your furnace’s igniter (if it has one).
- Turn the power back on.
- For gas furnaces, turn the main gas line back on.
- Press and hold the furnace’s reset button for 30 seconds (your furnace’s reset button should be near the main controls; if you need help locating it, check the owner’s manual).
- Finally, raise the temperature on your thermostat.
If you are uncomfortable resetting your own furnace, or suspect there may be other problems affecting your heating system, one of our Las Vegas furnace repair technicians can help you get it operating again. We service all makes and models, including Trane furnaces, Daiken furnaces, Carrier furnaces, Ruud furnaces, and more.

Glad I made the decision to call Sunrise AC. Cody responded very quickly. His quote was very fair. The installers did a great job installing the new units. We are very happy with the work. We highly recommend this company. Ask for Cody, he will lead you in the right direction.
We could not be more pleased with Mike H. who did our fall furnace maintenance and Kevin who did our first plumbing maintenance. I would like these same employees for my next maintenance service. Very professional, great attitudes, helpful with questions and pleasant to work with.
Jose has been doing semi annual maintenance and any necessary repairs on my units for years. He is dedicated, very experienced, and conscientious. Hat is also off to Mike, his manager. I have been using Sunrise for more than 15 years. Strongly recommended.
