The Honeywell thermostat is a very popular thermostat model in the market. People are widely using easy-to-use smart thermostats for their homes. But like every good thing it also comes to an end and needs a replacement.
How to remove old Honeywell thermostat from wall?
Well, it’s quite simpler than what you think. Turn off the power supply and remove the thermostat cover. After that, you need to unscrew the wires very carefully. Then remove the wires from the thermostat. Lastly, pull out the thermostat from the wall, and you are done.
Confused? Worry not! I got a whole guide explaining each step in detail! Let’s get started!
Basic Understanding of Thermostat Wiring
Replacing a used thermostat is a frequent electrical problem that everyone faces. To get started with the removal process, first, you need to understand the wiring.
The wiring for a thermostat is composed of low-voltage cables that are powered by the furnace circuit. Because the wires belong to different components of your HVAC system, they must be properly linked when you install your new thermostat.
Each color of wire connects to specific components of the Honeywell thermostat. This is why knowing what wire works for which part is very important.
There are wires of 7 different colors. Which wire connects to what part of the thermostat is given below:
- White wire: Connects to heating systems.
- Orange wire: Connects to the heat pump.
- Yellow wire: Connects to compressors.
- Green wire: Connects to fans.
- Red wire (H): Connect the thermostats with the heating system.
- Red wire (C): Provides consistent current flow of 24 VAC to your thermostat.
- Blue wire: It’s the ‘C’ wire or common wire.
Different regions might have different color codes for wiring. Keep that in mind!
Removing Your Old Honeywell Thermostat: 5 Easy Steps
You might know different ways to remove an old Honeywell thermostat. But most of them are time-consuming and difficult.
It might sound funny but using a plastic crafting knife is the easiest solution. It will also prevent dealing any harm to the wall surrounding the thermostat.
Before uninstalling an old thermostat, make sure there are no extra wires attached.
If you’re seeking the simplest process of removing an old Honeywell thermostat then keep reading. Here I’ll discuss a step-by-step guide to removing your old thermostat safely.
Step 1: Turn off Power Supply
Turn off the power supply to your HVAC system. If you don’t do that then getting shocked can be a very possible risk. It can even be life-threatening.
Step 2: Removing The Thermostat Cover
The next step is removing the thermostat from the base plate. To do that turn all accessible screws counterclockwise until they come off. Be careful where each screw went since you’ll need to replace them later!
Here I got some best suggestions for thermostat covers for you:
The recommended covers are very popular. You can go for any of them without any hesitation. Now let’s move to the steps again.
This step is best done while sitting down to avoid injury. Because if the Honeywell thermostat slips forward off the mounting plate you might injure yourself.
The Honeywell thermostat cannot be removed from the mounting plate by pulling. So you must unscrew all the screws first.
Four screws, two on the bottom and two on top, secure Honeywell thermostats to a base plate. Honeywell includes a tiny plastic piece under each screw that functions as protection.
It gives protection against water or dust from entering into your Honeywell thermostat. Be cautious not to pull too hard.
Step 3: Handling The Wires
The thermostat wiring can be seen after removing the cover. Honeywell developed it so that you can unplug without much worry.
You can also click a photo of the wiring before disconnecting them. This can act as a guide when installing your new thermostat.
It would be beneficial if you were more cautious while designating the wires. Mark the items according to how they’ve settled. Cut the masking tape into little pieces using a knife.
Start by removing the bracket as well as the thermostat wires. When disconnecting the wires with a screwdriver, use extreme caution.
If your house is comparatively old then you may also look for wiring problems. In case of any kind of problem, rewire your old house for the best safety.
Step 4: Remove The Wires
Most of the time you will see the wires fixed using screws. So you need to unscrew them and then pull out the wires. Be very careful while disconnecting the wires from the terminal.
Step 5: Remove The Thermostat
Pull the thermostat gently from the bottom. Ensure that all the screws are removed before starting pulling the thermostat. Thermostats are attached to the base plate using two wires and a power cord.
If a little pressure doesn’t work then try to pull it harder. But don’t pull it too roughly. Since it’s made of plastic it can easily be broken with too much force.
Well, there you have it. You have successfully removed your old Honeywell thermostat. But also keep in mind to troubleshoot your thermostat before deciding to replace it. Now let’s head on to the FAQ section.
Question: What tools do I need to uninstall my thermostat?
Answer: There are not many tools that you need. You’ll need a screwdriver and electric tape.
Question: How much will it cost to replace the Honeywell thermostat?
Answer: A new Honeywell thermostat might cost around $199 to $250 depending on the model. For a room of 2000 square feet, a thermostat may cost around $100 – $250 on average.
Question: Can an analog thermostat be replaced with a digital one?
Answer: Yes, of course! It’s even better if you are up for the upgrade. The digital thermostat will reduce your heating bills and assure more control over the temperature.
That’s all I’ve got today on how to remove old Honeywell thermostat from wall. If you are still unsure about replacing it then contact a professional.
