Safety Information
Important Safety Notice
HeartlandAppliances’ Service
Manuals are intended for use by
individuals possessing
electrical, gas and mechanical
experience. Therefore,
Heartland Appliances cannot be
responsible for the interpretation
of its Service Manuals by those
not having a background of
electrical, gas and mechanical
experience, nor can it assume

Safe Servicing Practices
To preclude the possibility of
resultant personal injury and/or
property damage, it is imperative
that safe servicing practices be
observed. The following are
examples, but without limitation,
of such safe practices:
1. Before servicing, always
disconnect the product from
its source of electrical power
by removing the product’s
electrical plug from the wall
receptacle or tripping the
circuit breaker to OFF(or
removing the fuse) in the
branch circuit servicing the
product.
Note: If a specific diagnostic
check requires electrical
power to be applied such as
for voltage or amperage
measurements, reconnect
electrical power only for time
required for specific check,
and disconnect power
immediatelythereafter.
During any such check,
ensure no other conductive
parts, panels or yourself
come into contact with any
exposed current carrying
parts.
3. If a replacement part is
required ensure it meets
factory specifications.
4. Never by-pass or interfere
with the proper operation of
any feature, part or device
engineered into the product.
5. Prior to reconnecting
electrical power service to
the product, ensure that:
a) all electrical
connections
within the product
are correctly and
securely
connected,
b) all electrical
harness leads
areproperly
dressed and
secured away
from sharp
edges, high
temperature
components
(heaters, etc.)
and moving
parts,
c) anyun-insulated
current-carrying
metal parts are
secured and
spaced
adequately from
all non-current-
carrying metal
parts,
d) all electrical
grounds (internal
and external to
the product) are
correctly and
securely
connected, and
e) all access panels
and covers are
properlyand
securely
assembled
followingthe
servicing and
prior to operating
the product.
6. On gas appliances, do not
disturb gas-carrying
components or connections
until gas service to it is shut
off, and do not use a flame
to test for gas leaks.
Following repair work,
ensure all gas connections
are properly secured by
testing for gas leaks with a
bubble (soap) solution.
7. Do not attempt a repair if you
have any doubts as to your
ability to complete it in a safe
and satisfactory manner.

Procedure 1 - Breakers & Fuses
Step 1: Be sure all range controls
are turned off.
Step 2: To restore power, turn the
breaker switch to “OFF” position,
then back to “ON” (when a breaker
trips, the switch moves to an
intermediate position between the
“ON” and “OFF” positions)
Step 3: If breaker trips again, the
circuit is still overloaded.
Step 4: Fuse blocks utilize a
double pole fuse block with two
cartridge type fuses joined together
at the handle.
Step 5: Pull block out of panel
Step 6: Fuses can be checked
with ohnmmeter set at the lowest
resistance scale. Touch probes to
brass caps at each end. If no
continuity then replace with fuse
that meets local electrical codes
and is not larger than specified for
the range.
Step 7: Clip fuses firmly back on
panel (“ON” notation should appear
at the top of the block). Loose
connections can cause the fuse to
overheat.
Step 8: Proper power readings on
receptacle can be tested with a
multimeter set to AC volts.
Step 9: With range unplugged,
place test probes as per diagrams.

Section 5-3
18 MLSM2003-01-03
Procedure 2 - Terminal Block
Step 1: Disconnect power supply
to range. Pull range away from wall.
Step 2: Remove back panel. Refer
to Procedure 32 for details.
Step 3: Inspect terminal block for
burnt terminal connections. If
damaged, replace.
Step 4: To replace terminal block,
remove power cord by unscrewing
the three screws that retain the
ends of the cord to the terminal
block.
Step 5: Mark and disconnect all
wires attached to the terminal block
(including wire to ground stud for 4
prong power cords)
Step 6: Terminal block can be
removed from range by removing
the two center screws.
Step 7: Install new terminal block,
attach all red, white and black wires
as originally marked
Step 8: Attach power cord back on
terminal block. Be sure all wires are
secure. 3 prong power cords have
jumper cable from center (neutral)
side of terminal block to stud. 4
prong power cords have copper
wire from cord directly attached to
ground stud.

Section 5-3
19 MLSM2003-01-03
Procedure 3 - Power Cord
Step 1: Disconnect power supply
to range.
Step 2: Pull range away from wall.
Step 3: Pull plug from receptacle
with a quick firm tug (do not pull by
the cord). Power cord
configurations are as follows:
3 prong 240V; 60 Hz (electric)
4 prong 240V; 60 Hz (electric)
Step 4: Inspect plug for damaged,
corroded or burnt terminals. Look
around molded portion for signs of
over heating. If damaged replace
cord.
Step 5: Remove back panel (Refer
to Procedure 32 for details.
Step 6: Inspect power cord
connection at terminal block.
Inspect wires and strain relief clamp
for signs of damage. If damaged,
replace. See Procedure 2 for
details.
Step 7: If no visible damage
detected, check individual wires in
the power cord with a multimeter.
Step 8: Place one test probe on
the wire end and the other test
probe on the plug end. If no
continuity, replace power cord.
Step 9: For 3 prong cords, outer
terminal wire end (black side)
should indicate continuity to one
(not both) outer terminals of plug.
For 4 prong wires, black and red
wires at terminal end correspond to
specific terminal ends at plug.
Twist cord to ensure no internal
break occurs - replace if needle
drops.
Step 10: To remove power cord,
unscrew the three screws that
retain the ends of the cord to the
terminal block.
Step 11: Attach new power cord to
terminal block securely.

Section 5-3
20 MLSM2003-01-03
Procedure 4 - Timer Replacement
Step 1: For oven to operate, time
of day must be set in timer. See
Timer Programming (Procedure 5)
for details.
Step 2: Disconnect power supply
to range.
Step 3: Legacy Models. With
edge of fingers, pry on timer’s
edges to dislodge from control
panel.
Step 4: Metro models. Remove
control panel (see Procedure 34).
Step 5: Disconnect coaxial power
supply cable by lifting both locking
tabs.
