Problem

Possible Cause

Correction

No Gas to oven pilot

Oven slow to heat; poor baking; poor ignition
of burners; pilots won't stay lit; popping
sound from top burners; carbon on pilot
shield; burner flame too low or high

Improper control-knob
setting
Defective gas pressure regulator

Set oven-control knob to "oven
pilot on" position
Have regulator tested

Oven pilots won't light or stay lit

Incorrect poilot adjustment;
damaged pilot tubing; defective
pressure regulator; incorrect
oven-control-knob setting

Adjust pilot; check pilot tubing for
kinks or clogs; have pressure
regulator checked; be sure oven
control knob is not in "pilot off"
position

Top burners won't light

Top burners and flash tubing out
of position; no pilot flame; air
shutter improperly adjusted;
clogged burner ports

Check and adjust position of
burners and flash tubing; check
and adjust pilot flame; adjust air
shutter; clean burner ports with a
toothpick

Gas smell

Leaky gas line

Check all connections with soapy
water; repair if necessary

Cake rises higher on one side than other

Uneven heat

Pans set too close to side of
oven; allow 2 inches from side.
Level range

Cake burns on bottom

Improper circulation

Oven too full for proper circulation
; remove item; do not use a pan
with a dark bottom

Oven will not operate

Pilot not lit

Relight pilot

Oven door not closing properly

Misaligned door

Open oven door and slightly
loosen four sheet-metal screw
holding the door panel to the liner

No constant pilot

No gas to range

Constant-pilot-selector key turned
off
Blocked tubing supply line


Blocked orifice


Blocked pilot



Pilot too close to oven burner
flame

Check gas supply; turn on LP-
gas tank
Adjust constant-pilot-selector key
to LP position
Disconnect tubing at source and
at pilot end and blow out to clear
passageway
Single tube pilot; disconnect
tubing from pilot and blow out to
clear orifice
Disconnect tubing from pilot;
remove orifice from pilot and
clean out blockage or replace
pilot
Adjust position of pilot assembly

No heater pilot

Thermostat turned off

Blocked tubing supply line


Blocked orifice


Blocked pilot

Turn thermostat knob to setting
above oven temperature
Disconnect tubing at source and
at pilot end and blow out to clear
passageway
Single tube pilot; disconnect
tubing from pilot and blow out to
clear orifice
Disconnect tubing from pilot;
remove orifice from pilot and
clean out blockage; replace
pilot

Oven will not maintain proper temperature

Oven bulb not in proper location




Oven bulb coated with foriegn
material

Oven bottom covered with
aluminum foil
Pilot flame not cycling off




Safety devices not closing; flame-
responsive element is being
heated by oven burner flame due
to either improper location or an
overrated oven burner

Safety device not closing when
flame-responsive element is not
being heated

Secure oven bulb in clips that
hold it in proper location; oven
buld should not touch any surface
; place approx. 1/2 inch away from
surface of oven drum top
Use fine steel wool or scouring
pad to gently clean surface of
bulb
High pressure can cause the
constant-pilot flame; check
pressure and adjust as
necessary, if that fails to solve the
problem, replace the thermostat
Check flame-responsive element
for proper location on burner pilot
; pilot burner must be properly
located on bracket, bracket must
be in proper location; check oven
burner rate
Replace safety device

No main burner flame

Thermostat set lower than oven
temperature
Closed over burner orifice
Flame-responsive element not
hot enough




Defective thermostat
Defective safety valve

Reset knob to higher temp

Readjust to rated input
Check position of flame-
responsive element; it must be
enveloped in the heater-pilot
flame; check gas pressure;  
check pressure regulator; repair
if necessary
Replace thermostat
Replace safety valve

Yellow tips on burner flame

Improper gas-air mixture

Open the air mixture on units
having adjustable air shutters;
orifice hoods may be out of
alignment

Flames blowing off ports

Excessive gas pressure; air
shutter opened too much

Close air shutter slightly; check
gas pressure regulator

Flames flashing back in mix tube

Gas-air mixture too lean 

Reduce air shutter opening;
check for sufficient gas pressure
