How do you adjust a thermocouple?

Adjusting the Thermocouple Correcting the first condition is a simple process. Simply shut off the gas, reach under the burner and push or pull the probe to reposition it. If the thermocouple is faulty, remove it by unscrewing it from the burner and pulling it out. Reverse the procedure to install a new one.

How do you position a thermocouple?

Mount the sensor end of the thermocouple at the pilot / flame into its supporting bracket next to the pilot flame tubing. A small nut or clip is used on many appliances to hold the sensor tip in proper position. Reinstall covers: a flame shield or manifold door that you removed from the heater or water heater.

How close should a thermocouple be to the flame?

about 1/2 inch
The flame should strong enough to cover about 1/2 inch at the end of the thermocouple tip. If the flame is too strong and not adjusted correctly, it will be blue and may make a hissing sound as the flame crosses the thermocouple. The pilot should be adjusted to reduce the intensity of the flame.

How do I reset my thermocouple?

Press the reset button on top of the box to turn on the pilot light. Hold the reset button between 30 to 60 seconds to give the thermocouple time to heat up. Release the button to see if the pilot light goes out. The pilot light should stay on after the reset.

Should the flame touch the thermocouple?

The pilot flame should touch the thermocouple at a specific level. If the flame is blue and weak, and barely reaches the thermocouple, it needs to be stronger. If it extends well above the thermocouple, it’s too strong.

How tight should a thermocouple connection be?

Proper tightness should be finger tight plus ΒΌ turn. Inspect thermocouple to ensure that it is fully engaged into pilot bracket. Adjust tip of thermocouple to be fully engulfed by pilot flame.

How should pilot burner be adjusted?

How to Adjust the Pilot Light Flame on a Gas Furnace

  1. Turn that screw counter-clockwise, and the flame should grow. Do this if you believe your flame is too low.
  2. Rotate the screw on the pilot light clockwise, and the size of the flame will decrease.
  3. Return the access place to the front of your gas furnace.

Can you over tighten a thermocouple?

When replacing a thermocouple, it is imperative to remember that the thermocouple cannot have any kinks in the copper tubing and overtightening the thermocouple will short the electrical signal to the gas control valve causing malfunction of the device.

Can you bypass thermocouple on furnace?

Realistically, you have just disabled the thermocouple, but you can also reach in and unclip it from its holding bracket where it meets the pilot light. In most cases it will be held on with a gravity clip, but some are held on with a screw that must be removed with a small screwdriver.

Can you adjust the flame on a gas furnace?

All you will need to do is to twist the adjustment screw of the flame till the flame goes from one and half inches to two inches, which is about 4 to 5 centimeters high. Look for the adjustment screw on the pilot assembly close to the gas valve if the control valve has this adjustment feature.

Is it OK to bend a thermocouple?

Yes, you can bend your thermocouple probe. Bending the thermocouple probe will not harm the probe unless bent to excess. Bending the thermocouple probe will allow for a more accurate reading in most cases, compared to when just the tip of the probe is sitting in the solution or vapor you are trying to monitor.
