Gas Water Heater Pilot Light Won T Stay Lit

Another possible reason why a pilot won t stay lit has to do with the flex tubing.

Gas water heater pilot light won t stay lit.

A bad thermocouple will shut off gas to both the pilot and the burner so the pilot light won t stay lit. This is also a likely cause if the pilot won t ignite at all. There is a chance that your thermocouple has simply gone bad and is the reason your pilot light won t stay lit. This tubing connects to the gas controller and will ensure a steady stream of gas.

In this case you may need to replace your pilot light. The thermocouple has been damaged. As a result the pilot doesn t get enough fuel to stay lit. These are the most common reasons why your heater s pilot light won t stay lit.

If your gas water heater doesn t stay lit you may have a defective control thermostat. The gas supply to the pilot assembly is controlled by this valve. Most recently manufactured water heaters function with the aid of a thermocouple. The light goes out due to improper venting or air supply.

The primary reason a pilot light won t stay lit is simply equipment malfunction. Sometimes this tubing will get kinked in places which will prevent proper operation. Remove the burner access covers and unscrew the nuts on the gas pilot and thermocouple lines. If this is the problem then unkinking the tube will occasionally resolve the issue.

Down draft from the ceiling fan draft at the bottom of the unit or high winds are also common reasons when the pilot would go out. Most of the time improper venting would cause the pilot outage on direct vent gas water heaters dv. A pilot light can also keep going out because of a problem with the thermocouple. Why does your heater s pilot light keep going off.

A faulty thermocouple or malfunction of the gas valve could be the culprit but the problem may be as simple as a draft coming from a crack in the wall or under the door. If you re fairly certain this is the source of the problem you will either need to have the thermocouple replaced or repaired. Turn off the control valve and the shutoff. Dirt and debris can collect in the pilot tube causing the flow of gas to be blocked.

Although a blocked gas line is one reason why the pilot light on a rheem water heater won t light or stay lit there are other reasons as well some easier to correct than others.
