generator is up to operating temperature.
NOTE: This led will cycle on and off even at idle.
Green (Solenoid Valve): When lit, it indicates that line
voltage is momentarily being supplied to the solenoid
valve coil.
NOTE: This LED is only lit for a split second.

minutes before use.
BLUE LIGHT BLINKING CODES (REFER ALSO TO THE
TROUBLESHOOTING SECTION)
Rapid Flashing: Under this condition, the generator
may, or may not get hot. The solenoid valve circuit is
disabled until the cause is corrected.
Possible Cause(s): An open thermistor or loose, burnt,
broken wiring in heating circuit or one of the two gen-
erator heaters is open, or faulty temperature Control
Board.
Slow Flashing (1 second on and 1 second off):
Under this condition, the generator surface temperature
has dropped below 280ºF (137ºC). The solenoid valve
circuit is disabled until the temperature rises above
280ºF (137ºC) and reaches proper operating temperature.
Possible Cause(s): The water pressure regulator is
improperly set or rotary switches are not correctly set or
one of the two generator heaters is open or faulty tem-
perature Control Board.
Slow Flashing (1 second on and 3 seconds off):
Under this condition, the electrical compartment tem-
perature has exceeded 155ºF (68ºC). The solenoid
valve circuit is disabled until the electrical compartment
temperature drops below 155ºF (68ºC).
Possible Cause(s): Insufficient ventilation around the
unit or faulty temperature Control Board.
