Finally, if the thermostat is still not working properly, you may need to replace the thermostat.

What Causes Auxiliary Heat to Not Work?

There are a few different things that can cause auxiliary heat to not work through your thermostat. One possibility is that the batteries in your thermostat are low and need to be replaced. Another possibility is that the settings on your thermostat are not properly configured to allow for auxiliary heat to come on. Additionally, if your furnace is not working properly, this could prevent auxiliary heat from coming on. The other potential issue is that your home’s ductwork could be blocked, preventing the heat from circulating properly. Lastly, if there is a problem with the wiring in your home, this could also prevent auxiliary heat from coming on.

Why Is It Important to Fix Auxiliary Heat?

If you are having trouble getting auxiliary heat to come on, it is important to fix the issue as soon as possible. This is because auxiliary heat is a crucial part of your home’s heating system and can help to keep you warm and comfortable when the temperatures outside are very low. Additionally, if your furnace is not working properly, auxiliary heat can help to take some of the strain off of your furnace and prevent it from overworking.

Another reason why it is important to fix auxiliary heat is that if your home’s ductwork is blocked, it can cause a build-up of heat in your home, which can be dangerous. Additionally, if there is a problem with the wiring in your home, this could also cause a fire hazard. Finally, having low batteries in your thermostat could cause your heating system to turn off unexpectedly, leaving you without heat.

10 Ways How to Fix Aux Heat on Thermostat:

1. Check the Batteries

One of the first things you should do if your aux heat isn’t working is to check the batteries in your thermostat. If the batteries are low, they may need to be replaced. To check the batteries, first, remove the thermostat from the wall.

Then, open up the battery compartment and check to see if the batteries are low. If they are, replace them with new batteries and then re-install the thermostat on the wall. Additionally, if the batteries are old, they may no longer be able to hold a charge. In this case, you will need to replace the batteries.

2. Check the Settings

If your aux heat is not working, another thing you can check is the settings on your thermostat. Ensure the settings are properly configured to allow auxiliary heat to come on.

Additionally, you can try changing the settings on your thermostat to see if this helps. To do this, first, remove the thermostat from the wall. Then, access the settings menu and change the settings to allow for auxiliary heat to come on. Once you have done this, re-install the thermostat on the wall.

3. Check the Furnace

If your furnace is not working properly, this could prevent auxiliary heat from coming on. To check the furnace, first, make sure that the power is turned off. Then, check the furnace itself to see if there is any debris or dirt build-up. If there is, clean it off and then turn the power back on. If the furnace still does not work, you may need to call a professional to come and take a look at it.

4. Check for Blockages in the ductwork

If your home’s ductwork is blocked, this could prevent the heat from circulating properly. To check for blockages, turn off the power to the furnace. Then, remove the access panel to the ductwork and take a look inside. If you see any blockages, such as dirt or debris, remove them and then re-install the access panel. Once you have done this, turn the power back on to the furnace.

5. Check the Wiring

If there is a problem with the wiring in your home, this could also prevent auxiliary heat from coming on. To check the wiring, first, ensure all the connections are tight. If they are, you will need to check for bare wires. If you find any, make sure to cover them with electrical tape. If the problem persists, you may need to call a professional to come and take a look. Try these troubleshooting tips if you’re having trouble with your auxiliary heat. With a little investigation, you should be able to fix the problem and keep your home warm all winter long.

6. Check the Thermostat

If your thermostat is not working properly, this could be preventing auxiliary heat from coming on. To check the thermostat, first, make sure that it is set to “heat” mode. If it is, then check the batteries and make sure they are fresh. If the batteries are good and the thermostat is set to “heat” mode, then you may need to replace the thermostat. Try turning the thermostat up to see if auxiliary heat comes on. If it does, then you know the issue is with the thermostat. If it doesn’t, then you’ll need to check the furnace.

Check the Batteries

7. Check the Filters

If your furnace has dirty filters, this could be preventing auxiliary heat from coming on. To check the filters, first, locate them. They are usually found in a slot on the side of the furnace. Once you have located the filters, please remove them and hold them up to a light. If you can’t see through them, it’s time to replace them. Replacing your furnace filters is a quick and easy fix that could solve your aux heat issue.

8. Check the Blower

If your furnace’s blower is not working properly, this could prevent auxiliary heat from coming on. Ensure the power to the furnace is turned on to check the blower. Then, check to see if the blower motor is running. If it is not, you will need to replace the motor. If the motor is running, check to see if the blower blades are turning. If they are not, you will need to replace the blades. If the blower is working properly, move on to the next step.

9. Check the Heating Element

If your furnace’s heating element is not working properly, this could be preventing auxiliary heat from coming on. To check the element, first, ensure power goes to the furnace. Then, use a multimeter to test the element for continuity. If the element is not working properly, it will need to be replaced. Try resetting the furnace by turning it off and then back on again. This may fix the problem and get your auxiliary heat working properly again.

10. Clean the Thermostat

If your thermostat is dirty, this could be preventing auxiliary heat from coming on. This is because dirt and debris can prevent the thermostat from connecting well with the wires. To clean the thermostat, turn off the power to the unit.

Then, use a soft cloth dipped in rubbing alcohol to gently wipe away any dirt or debris on the surface of the thermostat. Once you’ve cleaned the surface of the thermostat, reattach the cover and turn the power back on. The thermostat should now be able to work properly.

Tips and Warnings on How to Fix Aux Heat on Thermostat

Tips:

  1. Be sure to check your furnace filter and change it if necessary. A clogged furnace filter will prevent proper airflow and cause your system to work harder than it needs to, which can lead to aux heat being turned on more often than it should be.
  2. Inspect your ductwork for any gaps or leaks. Properly sealed ductwork will help ensure that your furnace is not working harder than it needs to and will also help prevent aux heat from being turned on more often than necessary.
  3. Make sure that your thermostat is set to the correct temperature. If your thermostat is set too low, your furnace will run more often than necessary and may cause aux heat to be turned on more often than it should be.
  4. Have your furnace serviced by a qualified technician regularly. This will help ensure that your furnace is running properly and will help prevent aux heat from being turned on more often than necessary.
  5. Consider investing in a programmable thermostat. A programmable thermostat can help you save money on your energy bill by allowing you to set your furnace to run less often when you are not home.

Warnings:

  1. Do not try to repair your furnace yourself unless you are a qualified technician.
  2. Do not ignore warning signs that your furnace is not working properly. These signs include strange noises, increased energy bills, and rooms that are not heated evenly.
  3. Do not turn off the aux heat without first consulting a qualified technician. Doing so could damage your furnace and lead to more serious problems.
