Water heaters go out at the most inconvenient times don't they? Have you tried re lighting your water heater with out success? This is a common problem with all water heaters and there are a number of different reasons why your water heater won’t stay lit.
The most common cause of a water heater that won’t stay lit is a bad thermocouple. The thermocouple is a safety device that shuts off gas to the water heater when there is no pilot flame. One end of the thermocouple sits in the pilot flame and the heat from the flame generates a voltage which holds open a magnetic switch in the gas valve. If the thermocouple fails no voltage is created even though the flame is lit and the gas valve shuts down the water heater.
This is fixed by removing the entire burner assembly, removing the bad thermocouple and replacing it. It is important that this is done by a licensed technician to ensure that it is installed correctly and everything is checked for gas leaks.
The second most common cause of a water heater that won’t stay lit is a bad gas valve. Gas valves are usually very reliable but they do fail from time to time. In this case the water heater needs to be drained so the gas valve can be screwed out of the tank and replaced.
Newer water heaters have additional safety mechanisms that may be causing problem with lighting and those will need to be diagnosed on site.
