When it comes to heating and cooling your home, that load generally falls on your furnace. However, with years of wear and tear, parts are bound to go bad. One of these parts is the thermocouple.
The thermocouple can go bad for several different reasons. No matter the cause, you’ll need to replace it to properly heat and cool your home. But what does a furnace thermocouple replacement involve? Keep reading to find out.
What is a furnace thermocouple?
A furnace thermocouple is a small and exceptionally thin piece of metal that’s responsible for sensing the temperature inside of a furnace. This sensor is important because it helps the furnace know when to start and stop burning fuel.
The thermocouple is attached to the furnace’s pilot light, and when the pilot light is lit, the thermocouple begins to produce heat. This heat is then used to measure the temperature inside the furnace. If the thermocouple senses that the furnace is too hot, it will tell it to stop burning fuel. If the thermocouple senses that the furnace isn’t hot enough, it will tell it to start burning fuel.
What causes a thermocouple to malfunction?
A thermocouple can malfunction for numerous reasons. One common reason is that the metal rod becomes dirty and clogged with soot. This can prevent the current from traveling properly and can cause the system to malfunction.
Another common reason for a thermocouple malfunction is when the wires become disconnected from the metal rod. This can happen if the wires are damaged or if they’re not properly connected to the rod.
Finally, a thermocouple can malfunction if it isn’t properly calibrated. This might happen if the metal rod is ‘t the correct length or if the wires aren’t properly connected to the rod.
What’s involved in a thermocouple replacement?
When it comes time for a thermocouple replacement, it’s important to call in a professional HVAC technician to get the job done. The thermocouple is a small, but important, part of your furnace, and it’s not something you want to try to replace on your own.
So, what’s involved with a thermocouple replacement? First, the technician will remove the old thermocouple. They will then check the wires to make sure they’re in good condition and are properly attached to the furnace.
If the wires aren’t in good condition, they’ll need to be replaced before installing a new thermocouple. Once the wires have been evaluated and potentially replaced, the new thermocouple will be installed, and the professional will ensure that it’s working properly.
They’ll also check the furnace’s pilot light to make sure it’s burning properly. If everything is working correctly, the HVAC technician will seal up the furnace. It’s critical to note that not all furnace thermocouples are created equal. Make sure you call in a professional who knows which thermocouple to use for your specific furnace.
How long does a replacement take?
A thermocouple replacement typically takes anywhere from 30 minutes to an hour, depending on the make and model of your furnace. It’s a relatively straightforward process, but it’s important to have a professional perform the replacement to ensure that it’s done correctly.
A professional can easily replace the thermocouple in your furnace in this timeframe. It’s a quick and easy process, and it will help ensure that your system is running properly.
Replace your malfunctioning thermocouple.
Overall, it’s vital to replace a furnace thermocouple when it begins to malfunction to maintain optimal furnace efficiency and prevent potential safety hazards. Not to mention, when your furnace is running at optimal efficiency, you’ll likely notice energy bill savings. Now that you know what’s involved in this process, you can better prepare for your HVAC technician’s arrival.
