What causes a pilot light to go out on a water heater?
Some of the most common reasons that water heater pilot lights go out include: A faulty thermocouple. Over time, thermocouples can begin to malfunction and shut off the gas supply to the pilot light even if it’s burning properly. A bent or dirty thermocouple.
Can I relight the pilot light by myself?
If your pilot light goes out, your furnace will not be able to produce heat because its burners will not ignite. Often, homeowners can relight the pilot themselves.
How do you light a hot water heater with an igniter?
Turn the water heat dial to Low and the On/Off/Pilot dial to Pilot. Then, turn the On/Off/Pilot dial downwards and push the igniter button at the same time. Let go of the igniter button, but keep pressing the Pilot dial downward for around 30 seconds. You should hear a “whoosh” sound when the gas is lit.
How 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.
How much does it cost to replace a thermocouple on a water heater?
Thermocouple – $20 to $150 The thermocouple is an apparatus that senses whether the pilot light is lit and triggers the gas control valve. Repairs typically cost about $150 to have it done professionally, though a new thermocouple itself only costs about $20 on average.
How much does it cost to relight a pilot?
Most service providers will charge a standard fee per visit that typically covers the cost to relight a gas water heater. This service call price can range from $80 to $100. Have you ever relit your own pilot light?
What do I do if pilot light goes out?
Your pilot light relies on your natural gas to stay aflame, so if your gas is shut off, your pilot light will go out. Simply turn your gas back on and either relight your pilot light yourself or call a professional.
How do I know if my pilot light is out?
How to Tell If the Pilot Light Is Out
- Locate the front cover panel on your furnace. It should be a little door that’s easily visible.
- If your pilot light is on, it should be easy to see – your eyes will be drawn to the little flame.
- If you don’t see a flame, your pilot light is out.
- If there is a flame, check the color.
Can I manually light my gas water heater?
Lighting the Pilot Light on a Manual Hot Water Heater If your hot water heater is a manual, grab a long lighter. Turn the pilot dial to the off position and wait 5-10 minutes for any gas to dissipate. Then, turn the pilot dial until it says the word pilot. After that, set your temperate knob to low.
What do I do if my water heater won’t light?
If you have a natural or propane gas water heater, chances are the pilot has gone out. If the pilot doesn’t relight, if it goes out right after lighting or if it goes out repeatedly, by far the most common cause is a bad thermocouple.
How do you relight an automatic pilot light?

- Set the thermostat on your furnace to its lowest setting.
- Remove the access panel covering the gas control knob.
- Turn the gas control knob to the OFF position.

If the pilot lights but the flame goes out as soon as you release the button after holding it for 60 seconds, then the thermocouple is bad. It’s possible to replace the thermocouple without removing the burner assembly, and many repair people do this.
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.
