Keeping this in view, how much does it cost to replace a furnace thermocouple?
Cost to Replace a Thermocouple on a Furnace Replacing a thermocouple costs $150 to $250, mostly due to labor time. On older models without an ignitor, it checks to make sure your pilot light is lit. If it's not, it'll shut the gas off.

Similarly one may ask, how long does it take to replace a thermocouple?
Replacing a Thermocouple Shut off the gas and electrical power to the furnace. Remove the furnace's access cover. If the furnace has been running, wait 30 minutes for the thermocouple to cool completely. Unscrew the nut that holds the thermocouple end fitting into the gas control valve, using an open-end wrench.
Are thermocouples universal?
Universal Thermocouples. Universal thermocouples, as the name implies work on most water heaters. They are available online and in home supply stores for a reasonable cost. The length and the thread type are the two concerns when purchasing one.
Related Question AnswersHow do you know if you have a bad thermocouple?
If you can't get the flame to light at all, and you're sure the gas is on, there's probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that's the sign of a thermocouple malfunction.Can you fix a thermocouple?
A burned out or broken thermocouple should be replaced. To replace a thermocouple: Step 1: Unscrew the copper lead and the connection nut inside the threaded connection to the gas line. Step 2: Under the mounting bracket at the thermocouple tube, unscrew the bracket nut that holds the tube in place.What causes a thermocouple to fail?
Changes in temperature can cause regular expansion and contraction in metal, which will cause thermocouples to weaken over time. After enough time, metal fatigue can cause a thermocouple to break. If thermocouples start to give out unusual readings, it may be suffering from metal fatigue.Can a furnace last 40 years?
While some furnaces can last over 40 years (extremely rare), the average lifespan of a typical gas furnace is around 15-30 years. As long as you have scheduled yearly furnace maintenance, your furnace should easily last over 15 years.How do you test a thermocouple?
Steps- Locate the pilot light controls on the gas valve.
- Turn the pilot light on for 30 seconds.
- Release the button to see if the pilot light goes out.
- Turn off the gas supply to test the thermocouple again.
- Count to 20 and wait for the pilot light to go out.
- Listen for clicking near the gas valve.
How long do blower motors last?
10 to 20 yearsWhat causes furnace circuit board failure?
If the starting capacitor is failing, it can cause problems with your system. Replacing the capacitor is an inexpensive fix to solve the problem. A blower motor that is failing can also blow a fuse. It cause strain against the motor and draw too much power, which causes the system to short.Can you clean a thermocouple?
If the Thermocouple is faulty it will cause the unit to shut down. How to clean? Remove Thermocouple from pilot assembly, using steel wool or emery cloth to lightly clean the tip removing any soot or build up that might have accorded due to an improper pilot flame.How do you troubleshoot a thermocouple?
Before the test, turn off the gas supply because you must first remove the thermocouple. Remove the thermocouple by unscrewing the copper lead and connection nut (first) and then the bracket nuts. Next, take your meter and set it to ohms. Take the two leads from the meter and touch them—the meter should read zero.What does thermocouple look like?
The thermocouple looks like a piece of metal tubing smaller than a soda straw. To find it, first locate the gas control box. This is the box that the main gas line enters, where you turn the gas on in the furnace. The other end of the thermocouple sits in the flame of the pilot light.Should a thermocouple be in the flame?
Typically the thermocouple sensor is mounted right in the flame of the pilot light on gas fired heating equipment. But not all of these systems use a thermocouple. Some gas fired heating equipment relies on an electronic ignition to ignite the flame. Those devices generally will not use a thermocouple.Does the length of a thermocouple matter?
The length of a thermocouple has no effect on its measurement accuracy or its ability to transfer the signal to the instrument. In other words, thermocouples do not experience “voltage drops” or power loss along its length as a high current power line might possess.How do you remove a thermocouple?
How to Replace a Water Heater's Thermocouple- Turn off the gas supply.
- Unfasten the three nuts that hold the thermocouple and the two gas tubes to the valve.
- Detach the thermocouple from the burner.
- Install the new one the same way that you removed the old one.
- Turn the gas back on and follow the lighting instructions on the water heater.
