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
any liability in connection with
their use.
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) any un-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 C - Timer Programming
Step 1: For oven to operate, time
of day must be set in timer.
Step 2: Press clock symbol
Step 3: Press increase or
decrease symbols to select
time
Step 4: Press start symbol to
set
Note: Pressing twice the clock
symbol toggles time of day

Step 1: Disconnect power supply to
range.Pullrangeawayfromwall
andremovebackguardheldby3
screwsand washers. See Proce-
dure A Step 1.
Step 2: PropTop Up.See Proce-
dure P.
Step 3: Markandremovewiring
ends from broil element by pulling
endsupandaway from element
terminals-please note sequence of
black and red wires to ensure they
areplaced on newelementin the
samesequence.
Step 4: Test for continuity. Place
test probes on each terminal.
Needleshouldreadapproximately
24 ohms for 3500W elements. 36”
models use two 2500W broil plates
and each plate has four leads. Test
the two outer and the two inner
leadsforapproximately 45 ohms.. If
noreadingorsignificantlydifferent

Step 5: If element faulty - Replace.
Step 6: Openovendoorandremove

pull element into oven cavity. Trans-
fer the wiring in same position as
originally.
Step 7: If broil element tests in
good condition, test continuity in
wiringto relay board, bake/limitbroil

Procedure E - Self Clean Latch Mechanism
Step 1: Disconnect power supply to
range.Pullrangeawayfromwall
andremovebackguardheldby3
screws and washers. See Proce-
dure A Step 1.
Step 2: PropTop Up.See Proce-
dure P.
Step 3: If self clean results are
poor, check all switches, wiring and
connections to self clean
microswitch.
Note: Black microswitch allows
signal from latch to confirm timer
that oven door is locked - this
allows self clean cycle to begin. If
latch is stuck or switch is
disconnected or faulty, self clean
will not commence.
Step 4: Test switch with multimeter
for continuity - switch is normally
open, close switch and test.
Step 5: To replace switch, with a
slot screwdriver push on the two
clips and pull the switch upwards
Replace black wires on new switch
in same two left positions, right
position is empty.
Step 6: Check microswitch to
cooling fan - top white switch.
Chech to ensure wiring is making
good contact to the two outer
positions(centerposition remains
empty). If incorrectly wired, unit will
not self clean properly since cooling
fanwillnotengage during self clean
and safety temperature limit in timer
willshutdownoperation.
Step 7: Test microswitch for
continuitywhen button is depressed
across terminals 1 and 2 by placing
test probes on terminals. If no
continuity in the on position, replace
switch.
Step 8: To replacem unscrew
microswitchfromsupportplace and
transferredwires from old switch.
Step 9: If all switches and wiringto
switches test in good order, latch is
not operational, Disconnect all
wires from micro switches, one at
the time and place on new latch
assembly.
Step 10: With short Phillips
screwdriverremovefourscrews
holdingassembly to top ofstove
Push both clips
away from
switch to release
Step 11: Replacewithnew
assembly
Step 12: LatchReplacement (latch
warpedorbent): Removetwo
Phillips screws holding latch in
place and replace with new latch.
Note: Donot over tighten screws
as they must allow movement of
the latch back and forth.
Self Clean Operation:
During selfclean,door automati-
cally locks (wax motor energized
and pushes latch to lock) and
coolingfan starts. temperatures
cycle off the timer.
When door locks, “black”
microswitch closes, sends signal to
timer to confirm door locked - unit
will begin self clean cycle.
If latch is stuck and door does not
lock, self clean program will shut
down.
If any of the 2 microswitches on the
selfclean assembly malfunction,
unit will not self clean properly.

Step 4: Pull locking tabs away and
releasecablefromrelayboard.
Step 5: Release coaxial cable from
timer(see Procedure B for timer
access).

testforcontinuity between fan and
terminal block and to fan limit.
Step 5: To access fan limit. Prop

ity. Remove both red wires and test
across, limit should be open and no
readingtakenacross terminals.
Step 7: If limit test in good condi-
tion, inspect self clean assembly
microswitch(seeProcedureC).
Step 8: If limit is faulty, replace.
remove wires to limit and transfer
red wires to new temperature limit.
Step 9: Remove one nut/bolt
holding limit to mounting bracket.
Note: Please ensure that red wires
do not run parallel with coaxial timer
cable or oven thermostat probe
when finished.

Step 4: Test wiring and connections
to spark module, particularly black,
whiteandgreenwiresto ensure
they are tightly connected.
Step 4: There should be no conti-
nuity across any of the correspond-
ing terminals from one side of the
module to the other. If any show
continuity, replace spark module.
Step 5: To replace faulty spark
module,removeonewire at a time
from old module and transfer to
new module in the exact same
terminals as the original. Please
ensure quick connect leads are
properlyandfully inserted into the
spark module spades (use pliers if
needed).
Step 6: Spark modules are held in
placebyvelcro.
Step 7: Test wiringfromspark
moduleto ignition switchesfor
continuity and/or wires to elec-
trodes. Replaceas needed.

Step 3: Beforereplacingregulator
becauseflames are toohighor too
low,checkregulatorcapfor proper
gas setting.
Step 4: Cap is stamped with either:
”NAT” on the convex side or “LP”on
the hollow concave side. If stove is
set for Nat Gas and it receives
Propane, the flames will be large. If
stove is set to Propane and it
receivesNat Gas, flames will be
small. See Procedure K for Gas
conversionsteps.
Step 5: If no gas flows through
regulator but there is gas to the
regulator,it is either mounted
backwards (although unlikely,
howeverthereisanarrowstamped
on the body of the regulator to
ensureproperorientation); or it is
faulty.
Step 6: If installed backwards,
disconnectregulatorfrommanifold
andinletpiping,reverseorientation
and re-install. Check all gas con-
nections with soapy water solution
to ensure no gas leaks.
Step 7: If regulator is faulty (i.e no
gas flow, leak, etc.) then replace
regulator.
Step 8: To remove regulator,
carefully rotate and unscrew from
manifold. Ensure new regulator is
oriented with arrow pointing in
directionofgasflowand ensure pipe
dope is used in all threaded connec-
tions.
Step 9: When finished check all
gas connections with soapy water
solution to ensure no leaks are
present.
