Thermocouple On A Propane Stove

There are a lot of stoves that use a thermocouple, but the most common one is a propane stove. To change the thermocouple on your propane stove, you need to know the exact model of your stove, so I put together a short guide on how to change the thermocouple on your propane stove.

While propane stoves are the most common type of stoves used by campers, they do have some limitations. First, you can’t easily change or repair them, and you can’t use other types of fuel (like wood, charcoal, or unleaded gasoline). As a result, propane stoves are more expensive than some other options.

Where Is The Thermocouple Located On A Gas Stove

When you turn on a propane burner, it gets super hot from the gas pressure. This heat is what keeps the burner lit and produces the flame. There is a metal rod inside the burner that is linked to the gas pressure and temperature of the burner. This is what is called a thermocouple. It is a small metal rod that gets very hot from the gas pressure and is used to measure the temperature of the burner.

How Do You Replace A Thermocouple On A Gas Stove

Thermocouples are one part of a propane stove, and they are very important. If you don’t know how to change it, you could have a dangerous situation.

If you have a propane stove and you want to change your thermocouple, you can do so easily. All you have to do is remove the old thermocouple, screw in the new one, and light.

Activate The Access Cover

  • Remove the access cover from the furnace. Wait at least 30 minutes for the thermocouple to cool completely before continuing if the furnace has been operating.

Remove The Old Thermocouple From The System

  • Unscrew the nut that holds the thermocouple end fitting into the gas control valve with an open-end wrench. There should be either a nut at the bottom of the bracket or two nuts, one below and one above the bracket, where the thermocouple is secured to the standing pilot burner assembly bracket. Remove the thermocouple by loosening the nut(s).

Replace The Thermocouple

  • Straighten the new thermocouple’s lead and shape it to look like the previous thermocouples. It’s unnecessary to be exact; simply start with a similar form. Tighten the nut(s) on the new thermocouple to the pilot burner assembly bracket until it’s just snug. Make sure you don’t over-tighten.

Re-Connect The Gas

  • Thread the thermocouple’s end, fitting it into the gas control valve, and tighten it by hand. Then tighten it about a quarter-turn more with the open-end wrench; do not over-tighten.

Turn On The Gas And The Power.

  • Turn on the furnace’s gas and electrical power. Turn on the pilot light and make sure the thermocouple reaches about 1/2 inch into the flame. Replace the furnace access cover and check the performance of the furnace by adjusting the thermostat settings to ensure the furnace turns on and off properly.

What Are The Symptoms Of A Bad Thermocouple

Perform a visual inspection after you’ve found the thermocouple. You’re looking for the following information:

  • Discoloration, fissures, or pinholes on the tube are all signs of contamination.
  • Signs of wiring deterioration or corrosion, such as missing insulation or bare wire.
  • Physical damage to the connectors can affect the test reading’s reliability.

If you can’t see any obvious abnormalities, it’s time to hire an HVAC contractor to examine your thermocouple’s performance.

Can You Replace A Thermocouple Yourself

Yes! But, there are several types of propane thermocouples and those are different sizes of “T” and “J” size thermocouples. So, if you are having a problem with your LP gas stove and you want to replace it with a stainless steel one with a new thermocouple, then you may need to check the size of the new thermocouple before you buy it. So you don’t buy the wrong one. However; if you can’t do this yourself, it is advisable you call a professional to help you install a new thermocouple. It should cost no more than $10.
