PROBLEM
The Gas Control
temperature sensor has detected
that the water temperature was too
high. Once this condition occurs,
the Main Burner and the Pilot Light
will be shut off. Since the Pilot light
will be off, should this condition
occur, this Flash Code will only
be displayed immediately after
the Pilot has been relit. Turn Gas
Control Valve/Thermostat knob to
OFF.
The temperature
(thermistor) is defective.
Gas Control Valve failure.
This condition only appears if the
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.
