Your module has been designed to be user-
servicable, assuming a basic knowledge of
the operation of electrical devices. This

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.
The lead cord plug configuration designates
whether your module uses a 15 or 20 amp

the three screws along the front of the
module and the two screws along each
edge of the module. Retain this hardware
for re-assembly.
e. Open the module by raising the
component chassis from the electrical
cover and placing the chassis top down
on a dry, non-flammable work surface. 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. After servicing, be sure to verify the routing
of each wire with the 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.
4. Assemble components using retained
hardware, making sure that no wires are
pinched between the cover and the
component chassis.
5. Install water pan/water bottle. Then, feed
cord through clearance hole in cabinet and
slide module into cabinet.
CAUTION: IT IS IMPORTANT THAT ALL
