How do you replace a thermocouple on a wall heater?
How do you replace a thermocouple on a wall heater? Lift the control cover and turn the gas control knob all the way to the “Off” position. Remove the thermocouple from its packaging and unwind it. Hold the probe, which is the small bulb on one end of the wire, between your fingers and reach into the burner.
Why does my Mr heater keep going out?
The problem with the heater shutting off is most likely due to not enough gas flowing through the pilot orifice (this orifice is almost as small as the diameter of a human hair). When this happens, the pilot flame does not burn vigorously enough to activate the thermocouple.
What to do if your water heater pilot won’t light?
The Pilot Lights But Won’t Stay Lit. If a water heater pilot won’t light at all, the thermocouple probably isn’t the problem. The procedure for lighting a standing pilot always includes lighting the flame, then manually holding in the gas valve to keep the flame burning and give the thermocouple time to heat up.
Why does my furnace pilot not stay lit?
The pilot won’t stay lit on my furnace, when I release the button it just goes out. This started occurring after I did some gas plumbing and had to relight the pilot. I suspected the thermocouple and replaced it, but this didn’t fix the problem.
What to do when your wall heater wont light?
If the gas is flowing but the pilot still won’t light, the pilot tube might be blocked. Reach into the combustion chamber and clear the tube with some compressed air. Turn off the gas and wait 10 minutes for any gas in the combustion chamber to dissipate before attempting to relight the pilot.
Why does my Williams wall heater not stay lit?
Please contact the Williams wall heater troubleshooting service. The pilot will not stay lit even after following the lighting instructions. This could be from loose of dirty valve connections or a defective generator or gas valve.
Why is the pilot on my gas heater not working?
A pilot that won’t stay lit could be the result of a blockage in the pilot tube. Turn off the gas, clear the tube with compressed air, and relight the pilot. If that doesn’t work, you may need to call a repairman to come and install a new thermocouple.
If the gas is flowing but the pilot still won’t light, the pilot tube might be blocked. Reach into the combustion chamber and clear the tube with some compressed air. Turn off the gas and wait 10 minutes for any gas in the combustion chamber to dissipate before attempting to relight the pilot.
What does a pilot light on a water heater do?
In furnaces and water heaters, and in some ranges and dryers, the pilot light is accompanied by a safety device called a thermocouple — a heat sensor that turns the gas off if the pilot flame is extinguished. Newer gas appliances have igniters that start the pilot light as needed.
What should I do if my pilot light won’t stay lit?
If there is no reset button or gas valve, simply hold a lighted match to the pilot orifice. Step 3: If the pilot flame won’t stay lit after several tries, it should be adjusted by a professional. Don’t try to adjust the mechanism or tamper with the gas line. ©2006 Publications International, Ltd.
