gas control/temperature knob has
been turned off and the thermopile
continued to produce electric
power. This condition can occur
if the thermopile does not cool
down as quickly as expected when
the unit is shut off. This condition
can also occur if the gas control/
temperature knob has been turned
off and the pilot continues to
operate because the pilot valve is
stuck in the open position.
Combustion chamber temperature
sensor circuit is open or shorted

following the lighting instructions on the water
heater's label. If this condition returns, replace
the gas control valve/thermostat. Contact a
qualified technician if you are uncomfortable
