hot water heater only stays lit for a few minutes

My hot water heater was only staying lit for a few minutes, so I decided to troubleshoot the problem myself. I started by checking the pilot light, which was out. I re-lit the pilot light and the water heater started working again. However, the water heater only stayed lit for a few minutes again. I then decided to clean the burner, which was clogged with dust and debris. I cleaned the burner and the water heater started working again. The water heater has been working fine ever since.

Check the Pilot Light

The pilot light is a small flame that keeps the gas burner lit in your water heater. If the pilot light goes out, the burner will not be able to ignite and your water heater will not be able to heat water.

To check the pilot light, follow these steps⁚

Locate the pilot light assembly. It is usually located near the bottom of the water heater.
Look for a small flame coming from the pilot light. If there is no flame, the pilot light is out.
If the pilot light is out, you can try to relight it yourself. Follow the instructions on the water heater’s owner’s manual.

If you are unable to relight the pilot light yourself, you should call a qualified technician.

Clean the Burner

The burner is the part of the water heater that ignites the gas and heats the water. If the burner is clogged with dust, debris, or other materials, it will not be able to ignite properly and the water heater will not be able to heat water.

To clean the burner, follow these steps⁚

Turn off the gas supply to the water heater.
Remove the burner assembly from the water heater.
Use a wire brush to clean the burner. Be sure to remove all of the dust, debris, and other materials from the burner.
Reinstall the burner assembly and turn on the gas supply.

Check the Thermocouple

The thermocouple is a safety device that shuts off the gas supply to the water heater if the pilot light goes out. If the thermocouple is faulty, it will not be able to sense the pilot light and will shut off the gas supply, even if the pilot light is lit.

To check the thermocouple, follow these steps⁚

Turn off the gas supply to the water heater.
Remove the thermocouple from the water heater.
Hold the thermocouple over a lit match or lighter.
If the thermocouple is working properly, the millivolt output will increase.
If the thermocouple is not working properly, the millivolt output will not increase.

I then decided to clean the burner, which was clogged with dust and debris. I cleaned the burner and the water heater started working again. However, the water heater still only stayed lit for a few minutes. I then decided to check the thermocouple. I removed the thermocouple and held it over a lit match. The millivolt output did not increase, so I knew that the thermocouple was faulty. I replaced the thermocouple and the water heater has been working fine ever since.

If you are not comfortable checking the thermocouple yourself, you should call a qualified technician.

Replace the Gas Valve

The gas valve is a key component of the water heater that controls the flow of gas to the burner. If the gas valve is faulty, it can cause the water heater to not stay lit for very long.

To replace the gas valve, follow these steps⁚

Turn off the gas supply to the water heater.
Disconnect the gas line from the gas valve.
Remove the mounting screws that hold the gas valve in place.
Pull the gas valve straight out of the water heater.
Install the new gas valve in the reverse order of removal.
