Gas Water Heater Pilot Light Won T Stay Lit

As a result the pilot doesn t get enough fuel to stay lit.

Gas water heater pilot light won t stay lit.

Most recently manufactured water heaters function with the aid of a thermocouple. A bad thermocouple will shut off gas to both the pilot and the burner so the pilot light won t stay lit. This control is part of the gas valve assembly and normally has a dial that will allow for temperature adjustment and will also have a probe that monitors the water temperature. Sometimes this tubing will get kinked in places which will prevent proper operation.

This is also a likely cause if the pilot won t ignite at all. If you ve checked everything else and the light continually goes out this is probably the cause. There is a chance that your thermocouple has simply gone bad and is the reason your pilot light won t stay lit. Why does your heater s pilot light keep going off.

These are the most common reasons why your heater s pilot light won t stay lit. The gas supply to the pilot assembly is controlled by this valve. Dirt and debris can collect in the pilot tube causing the flow of gas to be blocked. A pilot light can also keep going out because of a problem with the thermocouple.

The light goes out due to improper venting or air supply. In this case you may need to replace your pilot light. 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. If you re fairly certain this is the source of the problem you will either need to have the thermocouple replaced or repaired.

Most of the time improper venting would cause the pilot outage on direct vent gas water heaters dv. Another possible reason why a pilot won t stay lit has to do with the flex tubing. The thermocouple has been damaged. If this is the problem then unkinking the tube will occasionally resolve the issue.

Thankfully a dirty pilot tube is the easiest issue to fix. 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. The primary reason a pilot light won t stay lit is simply equipment malfunction. If your gas water heater doesn t stay lit you may have a defective control thermostat.

This tubing connects to the gas controller and will ensure a steady stream of gas.
