You’ll have a problem on your hands if you go to your digital thermostat to turn off the heat one day and your Honeywell Thermostat won’t turn off heat.
The thermostat is an essential component of your home’s HVAC system: without it, you won’t be able to control your air conditioning or heating.
If your digital display is dark in this scenario, examine your batteries. Check your wiring to see if there are any problems if your display screen is working. Another suggestion is to ensure that your thermostat is perfectly level.
If it isn’t, your thermostat’s mercury switch could cause an inaccurate temperature reading.
If you’re seeking Honeywell thermostat help, you’ve come to the right spot. Our guide will walk you through how to solve typical problems with the thermostat not shutting off the heat.
Below we will look at some of the most common reasons why your Honeywell thermostat won’t turn off the heat.
Reasons Why Your Honeywell Thermostat Won’t Turn off Heat?
Is the Honeywell thermostat fan still on? That’s not typical, to say the least. If your fan won’t turn off, you’re probably dealing with one of the below issues:
- Thermostat malfunction
- Damage Checking system for water
- The heating unit’s principal controller is broken.
- A faulty check valve.
It’s sometimes difficult to figure out what the problem is without first trying to address it and ruling out other possibilities.
In this regard, we’ve established several ways to aid you in recognizing and, ideally, addressing and permanently fixing the problem.
Honeywell Thermostat Won’t Turn Off Heat? Working Solutions
Method #1 Is your thermostat set to the proper “Heat” temperature?
To verify that the switches for your heating and cooling equipment are set to “ON,” check the settings on your thermostat and also verify the circuit breaker.
- If your thermostat is constantly blowing air, your thermostat’s fan setting may be set to ON.
- Set it to AUTO, which means the blower will only blast air out the vents when the air conditioner or furnace cools or heats the air.
Method #2 Check the Honeywell Thermostat
Firstly we need to check whether the thermostat is working as expected.
Step 1. Whether your thermostat uses batteries, check to see if they need to be replaced first.
Step 2. Turn the thermostat’s setting off if you’re confident the batteries are working or if your thermostat has a direct connection to your home’s electricity.
Step 3. Give your system some time to shut down and see what happens.
Step 4. If your system is still operating after 3 minutes or so, you may need to turn off the electricity to the entire heating system.
Method #3 Change Thermostat Settings
The simplest option is to set the thermostat to a setting that is at least a few degrees lower than the present room temperature.
The heat should switch off if the thermostat and heating system are both operational. If the unit refuses to switch off, you may need to turn off the power to the entire system.
Turn off the heating system’s power:
This is a move that many homeowners are hesitant to take. It should be simple if your system’s on/off switch is appropriately labeled.
Your furnace or boiler’s on/off switch is usually labeled and red in color. Simply turn off the light and give us a ring.
Method #4 Thermostat Not Controlling The Temperature Correctly
Your thermostat may be dusty, skewed on the wall, or in a location where it can’t obtain an accurate reading when it indicates one temperature but the room is another.
Step 1. Turn off the heating system’s power.
Step 2. Remove the lid from the thermostat. Most varieties can be pulled straight out, but read the manufacturer’s instructions to avoid breaking it.
Step 3. To softly and gently remove dust and grime, use a soft bristle brush or a vac with a brush adapter. Clean the two parallel metal strips on the thermostat with a soft cloth.
Step 4. Keep an eye out for rust. You can use an electronic contact cleaner to try to get rid of the corrosion. If your thermostat is old, consider upgrading to a newer type.
Step 5. If you have a mechanical thermostat (one that isn’t electronic or programmable), make sure it’s level on the wall.
Step 6. Use a little spirit level to check it.
Step 7. A thermostat should be placed around 5 feet above ground level.
Step 8. Replace the thermostat with a new programmed thermostat if none of these methods work.
Method #5 Is The Power Switched On?
Sometimes it can be the simple things to check that can determine the reasons as to why the heat won’t turn off.
- The first thing you should do is check to see if your thermostat is powered up. This is an easy procedure to follow.
- Examine your thermostat’s wiring to ensure that everything is in place and working properly.

Step 2. Turn off the power at the circuit breaker for a few moments.
Step 3. If you’ve misplaced your thermostat’s manual, you may usually find it on the internet.

Finally, there are a couple of reasons why your Honeywell thermostat won’t turn off the heat. The main reason for this is that your thermostat is set to ON, which means it will run continuously, rather than Auto, which means it will only work at particular times.
