BASIC TROUBLESHOOTING
Module operation basics:
When the power switch is on, the blower is always energized, circulating air, and the digital thermometer is always
displaying the cabinet temperature. A thermostat controls whether an element will be energized depending on the
thermostat setting and the air temperature it is sensing. The control knob is used to change the thermostat setting. When
a thermostat senses the temperature has gone below its set point, the thermostat contacts close, the appropriate indicator
will light and the heater element will begin to produce heat. When the thermostat senses the temperature has reached its
set point, the contacts open, the indicator light will go out and the heater element will stop producing heat.
Holding Module: The holding module has one heating element. It is in the air duct and heats up the air as it is circulated in
the cabinet. The thermostat senses the return air temperature and will energize the air duct element as required to heat up
the cabinet air. Some passive moisture can be introduced by filling a stainless steel pan with warm water and placing it on
large flat area of the heating module, in front of the air discharge cover.
Moisture Holding and Proong Module: There are two heating elements in these modules. One is in the air duct to
heat the air, and one is under the stainless steel water pan to heat the water and introduce moisture into the cabinet. One
thermostat senses the return air temperature and will energize the air duct element as required to heat up the cabinet air.
The other thermostat senses the air temperature around the water pan. It will energize the water pan element to heat the
water and release moisture into the cabinet.
Combination Proof and Hold Module: A combination proof and hold module has a mode switch, which allows the module
to act as either a holding module or a proofing module. Therefore, it has all the elements of both a holding module and a
proofing module. When the mode selector switch is set to HOLD, only the larger wattage air element is used. The stainless
steel water pan element is not used. When the mode selector switch is set to PROOF, the lower wattage air element and
the water pan element are used but independently controlled by individual thermostats. See the appropriate paragraph
above for more detail on how the Combination Proof and Hold Module operates in either holding or proofing mode.

Note: When heating element(s) are not energized, the amp draw for the blower and digital thermometer is approximately 0.8 to 0.9
amps.
Warning: Only factory-approved service agents should attempt to service, repair or replace electrical components, wiring or power cord.
1. Controls do not work (digital thermometer and indicator light(s) not lit):
a. Check that the cabinet is plugged in.
b. Check that the outlet has power. Is electrical service fuse blown or circuit breaker tripped?
c. Check that the power switch is in the “On” position.
d. Check the cabinet wiring from the power cord to the power switch and to the terminal block.
e. Power switch could be bad.
2. Temperature too hot:
a. Temperature set point is too high. Turn control knob down to a lower setting. Wait several minutes and see if
the displayed temperature decreases.
b. Thermostat may have failed with contacts closed. Check thermostat.
c. If displayed temperature exceeds 220°F (104°C):
220-240V
120V
