TROUBLESHOOTING GUIDE
3. Sparking occurs at
electrodes when all control
knobs are turned off
Disconnected switch lead or short
in switch lead
4. All burners that are turned
on have lighted but
electrodes are still sparking
B. Oven Burner
1. No main burner flame
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
Defective safety thermocouple 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
Defective thermostat (unit under
oven control knob) , no main burner
flame at any setting
2. Oven will not maintain
proper baking temperature
Oven bulb not in proper location Secure oven bulb in clips that hold it in proper location
Oven bulb coated with foreign
material (i.e. oven cleaner etc.) Use fine steel wool or scouring pad to gently clean the surface of the bulb
- NOTE: Replace carefully in locating clips
Oven bottom covered with aluminium
foil If foil blocks holes or slots in oven bottom, oven heat distribution will be
affected - remove foil
Utensils too large for oven reducing
free circulation of air Allow at least 1 1/2" to 2" (38mm to 5.0mm) clearance for air circulation
between utensils and between utensils and oven surface
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
Ground/Earth lead to module
disconnected or range chassis not
properly connected to ground/earth
by ground/earth lead or through
third prong of power cord plug,
combined with reversed power
supply polarity Check ground/earth connection of range chassis and ground/earth lead
connection to module
FOR ALL BURNERS EQUIPPED FOR REIGNITION
WITH " FLAME RECTIFICATION "
Check all switch lead connections for looseness and wires for damage
Problem Cause Remedy
A. Spark Ignition
1. No sparks when any control
knob is turned to “light”
No power to spark module - module
switch faulty
Check electrical supply to spark module with voltmeter - replace module
2. No sparks when one or
some control knob(s) is
(are) turned to “light”
Reignition electrode controlled by
knob switch is grounded or has
a high resistance leak
Electrode to far from burner
base
Check high voltage wires carefully for loose connections or pinches in the
wires; if connections are tight, replace high voltage wire
The igniter is on a eccentric pin, so rotating the igniter in its place will bring
the igniter closer to the burner base
5. One or more burners have
lighted but eletrodes are still
sparking
Pots or cooking utensils (i.e. griddle
plates) are too large and are
smothering the flame causing the re-
ignition to spark Use smaller sized pots or reduce size of flame. Do not use
griddle plate directly over top of grates. Heartland Appliances
sells a griddle kit #7602 complete with griddle support.
