Trouble Shooting Guide
FOR ALL BURNERS EQUIPPED FOR REIGNITION
WITH " AUTO RE-IGNITION "
Problem
Cause
Remedy
A. Spark Ignition
1. No sparks when any con-
trol knob is turned to “light”.
2. No sparks when one or
some control knob(s) is (are)
turned to “light”.
2. Oven will not maintain
proper baking temperarture
.
B. Oven Burner
1. No main burner flame.
5. One or more burners have
lighted but electrodes are still
sparking.
4. All burners that are turned
on have lighted but electrodes
are still sparking.
3. Sparking occurs at elec-
trodes when all control knobs
are turn
ed off.
No power to spark module - module
switch faulty.
Reignition electrode controlled by
knob switch is grounded or has a
high resistance leak.
Electode to far from burner base.
Disconnected switch lead or short in
switch lead.
High resistance or open connection
between spark output terminal and
H.V. wire receptacle. (spark will jump
small gap but sensing current will
not.)
Defective module.
Ground/Earth lead to module discon-
nected or range chassis not properly
conn
ected to ground/earth lead or
through third prong of power cord
plug, combined with reversed power
supply polarity.
Defective safety thermocouple.
Defective thermostat (unit under
oven control knob), no main burner
flame at any setting.
Oven bottom covered with aluminium
foil.
Utensils too large for oven reducing
free circulation of air.
Check electrical supply to spar
k module with voltmeter -
replace module.
Check high voltage wires carefully for loose connections
o
r pinches in the wires; if connections are tight, replace
high voltage wire.
The igniter is on an eccentric pin, so rotating the igniter
in its place will bring the igniter closer to the burner base.
Check all switch lead connections for looseness and
wires for damage.
Push receptacles firmly onto all terminals
Check positioning of shrink sleeving on receptacle -
should be flush with end of receptacle - trim if necessary.
Replace module.
Check ground/earth connection of ran
ge chassis and
ground/earth lead connection to module.
Make sure thermocouple is hand tightened +1/4 turn.
Replace safety thermocouple - NOTE: There are no field
adjustments for this control.
Replace thermostat above - always check gas pressure
before replacing thermostat..
Secure oven bulb in clips that hold it in proper location.
Use fine steel wool or scouring pad to gently clean the
surface of the bulb - NOTE: Replace carefully in locating
clips.
If foil blocks holes or slots in
oven bottom, oven heat dis-
tribution will be affected - remove foil.
Allow at least 1 1/2” to 2” (3.8cm to 5.0 cm) clearance for
air circulation between utensils and between utensils and
oven surface.
Pots or cooking utensils are too large
the reignition to spark.
use griddle plate directly over top of grates. Heartland
sells a griddle kit #7602 complete with griddle support.
Oven thermocouple is out of position.
Please refer to Figure 31 regarding proper thermocouple
placement.
