Why is my hot water heater not igniting?
When the water heater pilot light goes out, first try relighting it, following the directions on the water heater label. 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.
Why does my hot water heater igniter not ignite?
If the igniter fails, the burner will not light. To determine if the igniter is defective, first make sure the igniter is getting voltage. If the igniter is getting voltage, but it doesn’t glow, this indicates that the igniter is defective and should be replaced.
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.
What happens when pilot light goes out on water heater?
If the pilot light goes out, your water heater won’t be able to ignite the gas burner and therefore, won’t be able to heat the water.
Can you manually light a gas water heater?
Lighting a water heater is simple, no matter what type you have. Most newer models of gas water heaters have a simple ignition switch. In just a few steps the water heater is lit, no problem. If you’ve moved into an older house, though, you many have the kind of water heater that needs to be lit manually.
Why is my gas heater not igniting?
If your gas furnace initiates the start cycle but does not fire up, it’s likely because of a faulty, damaged, or dirty ignitor/sensor. This is a very common furnace problem—you can try to clean the sensor and replace the ignitor.
Why is my gas heater not lighting?
If your furnace won’t ignite, the source of the issue may be a broken flame sensor. The sensor is responsible for turning off the gas burners to avoid gas buildup. Once this component starts to malfunction, it may stop the burners from igniting altogether.
Why would pilot light go out?
Improper Venting & Airflow Sometimes a pilot light can go out as a result of some source of wind or air simply blowing it out. If this happens, there could be an issue with how your flue pipe is set up or how your system is venting.
Will gas shut off if pilot light goes out?
Since the thermocouple regulates gas going to the pilot, it should cut off on its own if the pilot ever goes out, but that’s only if it’s functioning correctly. If the thermocouple isn’t working properly, then it’s possible that it’s allowing gas to leak into the very room where the heater is located.
