B. MODULE
Your module has been designed to be user-
serviceable, assuming a basic knowledge of
the operation of electrical devices. This section
has been written to guide the user step by
step, and in layman’s terms, through the
dismantling and servicing of the module.
Before attempting to service your module, read
the appropriate Module Repair Procedures
(found elsewhere in this section) thoroughly. If
you do not understand the Repair Procedures
or prefer not to service your module yourself, or
if your warranty is still in effect, please contact
our Customer Service Department for the
factory authorized service agency nearest you.
CAUTION: IT IS IMPORTANT THAT ALL
SAFETY PRECAUTIONS PERTAINING TO
THE SERVICING OF ELECTRICAL DEVICES
BE OBSERVED AT ALL TIMES.
1. Dismantle your module for servicing per the
following instructions.
NOTE: To replace the Thermostat Knob, it is not
necessary to dismantle the module.
a. Make sure the power cord is not plugged
into an outlet. Be certain that the module and
any water in the water pan has cooled to a
temperature safe for handling.
b. To remove the module, eight thumb screws
must be removed from the ceiling of the
cabinet. First remove the water pan.
Separate the pan holder from the unit by
removing the four thumb screws.
c. At each corner of the cabinet ceiling remove
the retaining four thumb screws.
d. Lift the module from the cabinet and place
on a flat surface.
e. Unfasten the electrical cover by removing the
screws along the bottom sides and rear of the
module. Retain this hardware for re-assembly.
f. Lift the cover up off the module. Thread cord
through bushing. IF NECESSARY TO
RECONNECT THE OPENED MODULE TO A
POWER SOURCE, PRACTICE EXTREME
CAUTION SO AS NOT TO RECEIVE
ELECTRICAL SHOCK FROM EXPOSED
COMPONENTS.
2. Refer to the appropriate Module
Replacement Parts Diagram to identify the
internal components. Determine
malfunctioning component(s) by electrical
diagnostic procedures.
3. Refer to the appropriate column of the
Module Replacement Procedures Chart on
pages 10 and 11 for replacement
instructions.
4. After servicing, be sure to verify the routing
of each wire with the appropriate wiring
schematic before installing electrical cover
and connecting module to power source. Be
sure that the thermostat sensor tube does not
contact any electrical connections.
5. Assemble components using retained
hardware, making sure that no wires
are pinched between the cover and the
module platform.
