d. Blower is not circulating air:
i. Blower wiring is faulty or disconnected.
ii. Blower needs replacing.
4. Indicator light is not working:
It is rare that an indicator light will be defective but it is possible. The thermostat contacts may not be closing
and therefore the heater element is not being energized. Check the thermostat and pilot light and their
respective wiring.
5. No heat generated:
a. If the heat indicator light is on, but the cabinet does not draw the appropriate amperage per the chart on
page 11:
i. Air heater element may be faulty.
ii. The wiring to the air heater element may be faulty or disconnected.
iii. The thermostat may be faulty.
b. If the heat indicator light is not on, the thermostat contacts may not be closing and therefore the heater element
is not being energized. It is rare that the indicator light will be defective but it is possible. Check the thermostat
and pilot light and their respective wiring.
6. Moisture level is too low:
a. If the heat indicator light is on, and the cabinet draws the appropriate amperage per the chart on page 11:
i. Check that the water pan has water.
ii. A door is not closed or sealing properly.
iii. Moisture set point is too low. Turn moisture control knob to a higher setting.
b. If the heat indicator light is on, but the cabinet does not draw the appropriate amperage per the chart on
page 11:
i. Air heater element may be faulty.
ii. The wiring to the air heater element may be faulty or disconnected.
iii. The thermostat may be faulty.
c. If the heat indicator light is not on, the thermostat contacts may not be closing and therefore the heater element
is not being energized. It is rare that the indicator light will be defective but it is possible. Check the thermostat
and pilot light and their respective wiring.
7. Cabinet trips GFCI (ground fault circuit interrupter):
A GFCI receptacle protects against “ground faults” whenever an electrical product is plugged into the GFCI outlet
by constantly monitoring the electricity for any loss of current. If the current flowing out of the receptacle differs by
a small amount from that returning, the GFCI quickly switches off power to that circuit. The GFCI interrupts power
extremely fast to minimize the possibility of an electric shock.
a. The heater element may absorb some moisture into its casing and insulation during shipment or during long
periods of not being used (such as during the summer in a closed school kitchen). Plug the cabinet (without
water in the water pan) into a non-GFCI outlet, set the temperature to “10” and let it run for 30-60 minutes to dry
out any moisture the element may have absorbed. (If it trips the standard circuit breaker call factory approved
service agent.) After drying the element, plug the cabinet into the GFCI outlet; the cabinet should run without
tripping the GFCI.
b. If the cabinet still trips the GFCI, call a factory approved service agent.
