Whirlpool gas water heater pilot light will not stay lit.
Thankfully a dirty pilot tube is the easiest issue to fix.
Pilot will not stay on.
When the thermocouple detects the pilot light is off it will shut down the gas flow.
The flex tube is how the gas reaches the device and if the continuous flow of gas is interrupted the pilot light won t stay lit.
Dirt and debris can collect in the pilot tube causing the flow of gas to be blocked.
The thermocouple detects the pilot light as it can sense the heat the pilot light creates.
Diagnostic light does not give any indications and answered by a verified plumber.
This is also a likely cause if the pilot won t ignite at all.
Check along the tube to straighten it so there s no obstruction to the flow of gas.
The gas supply to the pilot assembly is controlled by this valve.
The function of the thermocouple in your gas furnace is to check to see if the pilot light is on or off.
No gas or faulty gas valve does not release the gas.
If your gas water heater doesn t stay lit you may have a defective control thermostat.
As a result the pilot doesn t get enough fuel to stay lit.
Check the flex tube.
This is all done as a safety feature so there are no gas leaks.
When troubleshooting the pilot light problems such as when it does not stay lit keep in mind that there are often different causes for this and other conditions.
