Honeywell Thermostat Keeps Going Up To 85 Degrees (Fix)
If you’ve noticed your Honeywell thermostat keeps going up to 85 degrees, you’re not alone. This issue can be both puzzling and frustrating, especially when you’re trying to maintain a comfortable indoor temperature.
In this article, we will explore the common reasons behind this problem and provide step-by-step solutions to fix it.
Common Reasons Why Your Honeywell Thermostat Keeps Going Up To 85 Degrees
There are several possible causes for your thermostat behaving unexpectedly. Here are the most common ones:
1. Thermostat is in Heating Mode
One of the most common reasons your Honeywell thermostat keeps increasing to 85 degrees is that it may be set to heating mode instead of cooling mode.
When the thermostat is in heating mode, it will keep increasing the temperature until it reaches your desired setting, which can often be much higher than the current temperature in your home.
2. Incorrect Thermostat Settings
Another possible cause is incorrect settings. If the temperature setpoint is inadvertently raised, the thermostat will keep trying to heat the space to that higher temperature.
Sometimes, this happens if the settings are changed unintentionally or if a program mode is set incorrectly.
3. Faulty Thermostat Sensor
If the temperature sensor inside your Honeywell thermostat is malfunctioning, it can send incorrect readings, causing the thermostat to increase the temperature.
A faulty sensor can make the thermostat think your home is cooler than it is, thus increasing the setpoint.
4. Wiring Issues
Wiring issues in your thermostat system can also lead to erratic temperature readings and behavior. Loose or faulty wires might send incorrect signals to the thermostat, causing it to malfunction and raise the temperature.
5. External Temperature Interference
If your thermostat is located in a place that is affected by direct sunlight or drafts, it may receive inaccurate readings of the ambient temperature. This could trick the thermostat into thinking the temperature is too low and it needs to increase the heat.
How to Fix the Issue of a Honeywell Thermostat Keeps Going Up To 85 Degrees
Now that we know some of the causes, let’s dive into the solutions that will help you address the issue effectively.
1. Check and Adjust Thermostat Settings
Start by checking if the thermostat is in heating mode. If it is, switch it to cooling mode or adjust the temperature setpoint to your desired comfort level. This simple fix could resolve the problem quickly.
2. Replace the Thermostat Sensor
If the sensor is faulty, replacing it will likely solve the issue. Many Honeywell thermostats have a replaceable sensor, and it’s relatively easy to do. Consult your thermostat’s manual for specific instructions or call a professional if you’re unsure.
3. Verify Wiring Connections
Ensure that the wires connecting your thermostat are intact and properly connected. If you’re not comfortable working with electrical components, it’s best to call a certified HVAC technician to inspect the wiring and make any necessary repairs.
4. Reposition the Thermostat
If the thermostat is in a location that receives direct sunlight or drafts, consider moving it to a more central location in your home where it can get an accurate reading of the overall temperature. This can significantly improve its performance.
5. Reset the Thermostat
Sometimes, resetting your Honeywell thermostat to its factory settings can help clear any glitches or errors. Refer to the user manual for instructions on how to perform a reset. This can be a quick and effective solution for fixing any issues with your thermostat.

Why does my thermostat keep going back to 85 degrees?
Your thermostat might keep going back to 85 degrees due to a few common reasons:
Heating Mode: If it’s set to heating mode, it will continue to increase the temperature until it reaches the setpoint.
Incorrect Settings: The temperature setpoint may have been raised unintentionally.
Faulty Sensor: A malfunctioning temperature sensor could be causing inaccurate readings.
Wiring Issues: Loose or faulty wiring can send incorrect signals to the thermostat.
External Factors: Direct sunlight or drafts near the thermostat might affect its readings.
Why does my Honeywell thermostat keep changing temperatures?
Your Honeywell thermostat might keep changing temperatures due to a few reasons:
Incorrect Settings: The temperature setpoint might be accidentally adjusted.
Faulty Sensor: A malfunctioning sensor can cause inaccurate readings.
Wiring Issues: Loose or damaged wiring can disrupt signals.
External Factors: Sunlight or drafts near the thermostat may affect its readings.
Program Settings: If it’s set to a schedule, it may be adjusting based on preset times.
Why does my thermostat keep setting itself to 82?
Your thermostat might keep setting itself to 82 due to:
Program Settings: It could be set on an automatic schedule that adjusts to 82 at certain times.
Faulty Sensor: A malfunctioning sensor might cause inaccurate temperature readings, leading to the change.
Incorrect Settings: Someone might have accidentally set it to 82, and it keeps reverting to that setting.
Wiring Issues: Loose or damaged wiring can interfere with the thermostat’s functionality.
Why does my thermostat temperature keep rising?
If your thermostat temperature keeps rising, it could be due to:
Heating Mode: The thermostat may be in heating mode, causing it to raise the temperature.
Faulty Sensor: A malfunctioning sensor might give incorrect readings, causing the temperature to rise.
Incorrect Settings: The temperature setpoint might have been unintentionally raised.
External Factors: Direct sunlight or drafts can affect the thermostat’s temperature readings.
Conclusion
Having a Honeywell Thermostat Keeps Going Up To 85 Degrees can be frustrating, but by following the steps above, you can usually pinpoint and resolve the issue.
Whether it’s adjusting settings, replacing a sensor, or fixing wiring problems, addressing the root cause of the problem will bring your thermostat back to normal functioning.
If you’re unable to resolve the issue on your own, don’t hesitate to call a professional HVAC technician for assistance. With a little troubleshooting, you’ll be able to enjoy a comfortable and well-regulated home temperature once again.
