Upkeep makes use of turning off the aviator each spring and relighting it each fall. Newer, more effective gas heaters utilize an electric stimulate to light the gas as required.
What Can Go Wrong?
Many gas heating systems are rather trusted. Exactly what are the signs of issues? The furnace might not produce heat or could not produce sufficient heat. The pilot light could go out repeatedly or refuse to light. The thermocouple could be faulty. The aviator could light however not ignite the burner. The heater might be noisy.

Fix-It Tip
To decrease problems with your gas furnace, take time each month to examine the air filter and clean or change it if needed. As soon as a year, clean the blower blades, lubricate the blower motor, and examine the belt.
How Can I Identify the Problem?
If there is no heat, inspect the electrical service panel for a burned fuse or tripped breaker. Relight the pilot burner (see below).
If there is not nearly enough heat, readjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not remain lit, clean the aviator orifice thoroughly with a toothpick, test the thermocouple and change it if it is defective (see below).
If the flame flickers, readjust the aviator (see below).
If there is a blowing up sound when the burner ignites, adjust the aviator to a higher setting and cleanse the pilot orifice and the burner ports.
If the burner takes more than a few seconds to spark, clean the aviator orifice and adjust the pilot burner.
If the burner flame is uneven, clean the burner ports. If the burner flame is really yellow, clean the burner; open vents in the heating system room to offer more air; adjust the burner air shutter.
If the heater makes a rumbling noise when the burners are off, clean the burner and adjust the burner air shutter.
If the air is too dry, wash or change the evaporator pad if you have a humidifier; test the humidistat; and adjust the water-level float to raise the water level.
If some spaces are too cool and others too warm, the distribution system may require balancing. Describe the Forced-Air Distribution Fix-It Guide at FixItClub.com

To light the aviator on a standing-pilot (constantly on) ignition system, follow the lighting guidelines located near the control. Otherwise, attempt these steps:.
Light the aviator:.
1. Press and hold the pilot control knob to begin the aviator. Set the control knob to the aviator position. Hold a long match under the pilot gas port.
2. Press the control knob; the aviator needs to light. Hold the control knob down till the flame is burning brilliantly (about 30 seconds). Launch pressure on the knob, and turn it to the on position.
3. If the aviator goes out when you release the control knob, try relighting, holding the control knob down longer. If the pilot again goes out, check the thermocouple (below).
Readjust the aviator:.
1. Eliminate any cap covering the pilot adjusting screw on a combination control.
2. Turn the adjusting screw counterclockwise to increase the flame or clockwise to decrease it. It is correctly readjusted when the flame envelops the thermocouple bulb by 1/2 inch and appears dark blue with a small yellow pointer.
Test and replace a thermocouple:.
1. Hold the control knob to aviator and light the aviator as above.
2. Unscrew the thermocouple fitting with an open-ended wrench.
3. Set a multimeter to the DVC (most affordable voltage) scale.
4. Clip one multimeter lead to the end of the thermocouple tube nearest the aviator and the various other cause the fitting on the various other end of television.
5. If the multimeter shows a reading besides absolutely no, the thermocouple is functioning. Replace the thermocouple tube.
6. If there is no reading, you will need to clean or replace the thermocouple following steps 7 with 11.
7. Release the control knob and shut down the main gas valve on the gas-supply pipeline that leads into the burner. Turn off power to the burner at the electrical service panel.
8. Get rid of the thermocouple from its mounting bracket.
9. Wipe the mix control clean and set up a new thermocouple, tightening it by hand, then offer it a one-quarter turn with a wrench.
