By One Hour Heating & Air Conditioning Honeywell thermostats are some of the most trusted and reliable thermostats on the market—but even the best technologies are subject to necessary reset and repair! If your home seems to be off a few degrees, if you’ve noticed your energy bill going up unexpectedly, or if your thermostat fails to trigger your heating and cooling system, it may require a reset. What Is Wrong with My Honeywell Thermostat?Resetting your thermostat can solve several issues, including:
What Honeywell Thermostat Do I Have?To reset your thermostat, you’ll need to know the model. If you still have the product packaging or the thermostat ID card, your model number will be written on either of those items. If you don’t have that packaging on hand, you can remove your thermostat from the wall and locate the product number on the back of the wall plate. Most thermostats can be gently lifted from the wall without tools. Pull evenly from either side of the thermostat. If it won’t come off, you may need to search online to find models based on their resemblance to your thermostat.

Display Screen is BlankIs your Honeywell thermostat not working, or does the display screen appear blank? This is one of the more common thermostat problems. If this issue happens with a programmable thermostat, try replacing the batteries. If that doesn’t fix things, there could be a problem with your wiring. The next step is to check the power source. On the indoor unit, make sure the switch is in the “up” position. Another tip is to ensure all doors and panels are closed properly on your unit. Closely examine both your indoor and outdoor systems to see if any of these compartments are left open. Close them if that’s the case, and make sure they’re tight. If one of these panels isn't secure, it could trigger a safety switch that powers off your unit. A common mistake that homeowners make is assuming their thermostat is broken and must be replaced. Although that’s true in some cases, a blank screen rarely ever indicates a broken thermostat. Problem Inside ThermostatOn some occasions, a Honeywell thermostat not working could mean the inside of the equipment has an issue. To troubleshoot this, head over to your electrical breaker box and turn off the power that runs to your thermostat. This is to prevent electrical shock or cause any issues when looking inside. Then, carefully remove the cover and examine the wiring inside your thermostat. Check to make sure nothing is detached or broken. Also, ensure everything looks clean. If you don’t find any problems, the issue could lie with your HVAC system. If you have an old and aging thermostat, replacing it is another option that may work. Indoor Temp Doesn’t Match Thermostat ReadingAnother one of the common Honeywell thermostat problems is a thermostat that reads a temp that doesn’t match the actual temperature in the room. For example, your thermostat may read 80 degrees when your house feels more like 60 degrees. In this case, you could have a broken or malfunctioning temperature sensor. All thermostats have these sensors; it helps the device understand and maintain indoor temps. So when these break, your thermostat may have no idea what temperature it actually is in your home. To solve this issue, use a standard thermometer to measure the actual temperature near your thermostat. If these numbers don’t match up, a broken sensor could be the problem. You can either replace the sensor or buy a whole new thermostat. Speak with a local HVAC professional to help choose the best option for your needs. Test the SettingsIs your Honeywell thermostat not cooling? If you suspect a problem with your system, test the settings to ensure everything is working as it should. If you have an analog thermostat, you should have an option for heat, cool, or off. You probably also have a switch to change your fan settings to auto or off. The easiest test for your thermostat is to switch to heat and crank the temperature up. If your heater turns on, your heating system is working. You’ll then want to do the same thing for your air conditioner. Move the switch to cool and crank down the temp. If your unit powers on, you're in luck. Honeywell Thermostat Not CoolingIs your thermostat set to cool, but your air conditioner won’t kick on? If you signed up for a saver switch, your utility company may be locking you out of the system.
