Appendix C: Troubleshooting
PROBABLE CAUSE
a. Lack of gas supply.
b. Obstruction in burner orifice.
PROBLEM
Burner will not light.
REMEDY
a. Ensure gas supply valve is in open position or fill LP
gas cylinder, if applicable.
b. Clean burner orifice (See Fig. 8, Pg. 10).
Burner output at HIGH
setting is too low. (Cooks
more slowly than
previously experienced or
makes a rumbling noise
and has a fluttering blue
flame at burner surface.) a. Lack of gas supply.
b. Kinked regulator hose.
c. Insufficient gas pressure despite ample gas supply.
This may result when Burner Output Knob is very
quickly turned from OFF to HIGH with the gas
supply valve open, or if the gas supply valve is
opened AFTER the Burner Output Knob is
turned from OFF to HIGH. Both actions may
cause the regulator to shut off gas supply as if there
is a leak in the line.
d. Dirty or clogged orifice.
e. Venturi tube obstructed by spider or spider webs,
wasp nest, or other foreign matter.
f. Regulator is defective or needs adjustment.
g. Cracked burner.
a. Ensure gas supply valve is in open position or fill LP
gas cylinder, if applicable.
b. Reposition regulator hose, as necessary.
c. Return Burner Output Knob to OFF. Make sure gas
supply valve (at LP cylinder or nat. gas line) is open.
Then, when turning the gas on as instructed on pg. 9-
10, turn Burner Output Knob SLOWLY from OFF to
HIGH.
d. Clean burner orifice (See Fig. 8, Pg. 10).
e. Clean out all obstructions from venturi tube. (See Fig.
8, Pg. 10).
f. Adjust or replace regulator, as necessary.
g. Contact TEC Authorized Dealer. Replace ceramic
burner head.
Burner output at LOW
setting is too hot (or too
cool). a. Reduce (or increase) low heat setting following
procedures on Page 11.
Burner backfires (during
operation burner abruptly
makes a loud “woosh”
sound, followed by a
continuous blow-torch type
sound and grows dim).
a. Burner overheated due to inadequate ventilation
(too much cooking surface covered).
b. Cracked ceramic.
c. None of the above. Probable cause is leak in
packing within or under ceramic burner head.
I n all cases turn Burner Output Knob to OFF position
and let it cool for at least two minutes; then:
a. Remove any object covering the entire cooking surface
or any object obstructing the ventilation openings.
Allow the burner to cool for approximately two
minutes, then re-light the burner.
b. Allow burner to cool and inspect very closely for cracks
(which may be nearly invisible). If cracks are found,
contact TEC Authorized Dealer to replace burner
head.
c. Contact TEC Authorized Dealer. Replace fiber
insulation packing under burner head.
Burner will light with a
match, but the igniter will
not spark. a. Igniter wire has come unplugged from backside of
igniter.
b. Dirty ignition electrode.
c. Incorrect spark gap.
d. Defective igniter.
a. Remove cooking grid, glass and heat shield and tug on
igniter wire to determine if it is secure. If necessary,
plug in igniter wire and make sure it is firmly secured.
b. Clean burner electrode (See Fig. 10, Pg 14). If
necessary rub probes with fine sandpaper to remove
residue.
c. Adjust spark gap to 1/8”.
d. Replace igniter.
