.

Remove the light cover.
Remove the burned-out bulb. Replace it with a 5-watt halogen
appliance light bulb only. Don't touch bulb with greasy fingers.
Follow bulb manufacturer's instructions.
4. Replace cover. Turn circuit back on, if need be. (See Caution.)
CAUTION:
Before replacing the light
bulb, be certain the Oven
Light Switch is in the off posi-
tion. Let bulb and cover cool
completely before touching.
If the light bulb glass comes
loose from the base, turn the
power to the oven OFF at the
circuit breaker panel, before
attempting to remove the
bulb base from the socket.
POWER FAILURE
In the event of a power failure, only the standard
burners can be lighted manually. It is necessary to
light each standard burner individually.
If the range's cooktop is being used when the power
failure occurs, turn all of the burner control knobs to
the OFF position. Then, the standard burners can be
lighted by holding a match at the ports and turning
the control knob to the HI position. Wait until the
flame is burning all the way around the burner cap
before adjusting the flame to the desired height.
The two ExtraLow ® burners on the far left side cannot
be used during a power failure. Be sure to turn them
OFF if a power failure occurs because they will not
turn back on until both control knobs are turned OFF
and then turned back on again. See "What to do if
you Smell Gas," inside front cover.
If you have low gas pressure, contact your gas
company.
