ERROR 162
BURNER HEAD HIGH TEMP LIMIT BEFORE FLAME ESTABLISHED:
The burner
body high temp limit was reached before flame was established. If this problem persists,
try the following:
•
Check that Air Inlet High Temperature Switch (AIHT) is not set too low (180
°
F
is normal setting).
•
Check that the burner body thermocouple is connected using Type-K
thermocouple wire to the temperature controller and that the wire is not loose.
ERROR 163
HIGH TEMPERATURE CONDITION AT BURNER:
This error will shut the burner down
due to a high temperature condition sensed in the air inlet screen area, before the burner
head, by the AIHT switch. This temperature sensor will only be exposed to flame or
excessive heat when air through the Humidaire Unit is suddenly interrupted, causing the
flame to go in a direction other than the spray chamber. This can be caused by opening
the spray chamber door during operation. It can also be caused by not cleaning the air
inlet screen. See ERROR 162 for more details.
ERROR 164
BAD WATER THERMOCOUPLE:
The integrity of the thermocouple wiring and
thermocouple is checked during the pre-ignition checks each time the Humidaire Unit is
started. This error occurs when the water thermocouple (TCW) connection is an open
circuit indicating a loose wire or a failed thermocouple sensor.
ERROR 165
BAD AIR THERMOCOUPLE:
The integrity of the thermocouple wiring and
thermocouple is checked during the pre-ignition checks each time the Humidaire Unit is
