How do you fix a pilot light on a gas water heater?
How to Fix the Pilot Light of Your Water Heater
- The first step is to open the cover or door of the pilot light access.
- With the help of a flashlight or headlamp, identify the burner inside.
- Now, turn and press the knob to ‘Pilot’, and hold it for some seconds.
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.
What do you do if your pilot light won’t light?
If your pilot light won’t stay alight, it might be the thermocouple. Sometimes dust buildup collects on the thermocouple and blocks the sensor. Try cleaning the thermocouple and then relighting the pilot light. If it continues to go out, the thermocouple might need to be replaced.
Why is my water heater pilot not working?
The water heater pilot light is a small flame that ignites the gas burner on your water heater. 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.
Should pilot light always be on water heater?
The pilot should be on the water heating the house. The pilot flame can be difficult to see through a window. To know if the pilot is on or off, you need to remove the access door and shield and look at the burner and pilot through it.
Does gas still flow when pilot light goes out?
If your pilot light repeatedly goes out, this is a likely culprit. If this flame sensor should fail, gas will continue to flow even after the pilot light has been extinguished, causing a safety hazard, and requiring immediate repair.
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.
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.
Why is my gas heater not igniting?
The Pilot Light (Faulty Ignition Sensor) The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. This is typically the problem if you can hear your furnace click on but it does not fire up. If the sensor or ignitor is dirty, it will need to be cleaned.
How do you clean a thermocouple on a gas water heater?
Clean the thermocouple – using the emery cloth sandpaper, sand the ends of the thermocouple and then give it a finishing touch with the lint-free cloth. Hopefully, you can get to the ends of the thermocouple without having to detach it from the assembly, but you may have to do that.
