6.1 General
DANGER
Hot cooking oil will cause severe burns. Never attempt to move this appliance when
filled with hot cooking oil or to transfer hot cooking oil from one container to
another.
The problems and possible solutions covered are those most commonly encountered. To
troubleshoot, perform the test set-up at the beginning of each condition. Follow each step in
sequence.
6.2 Pilot Burner Malfunction
A. Pilot will not ignite. No evidence of gas at pilot burner.
1. Check that incoming service line gas valve is open and gas is present at the gas valve.
2. Check pilot burner orifice for dirt or lint.
3. Remove pilot burner gas-supply line and check for contamination; blow out if necessary,
then reinstall.
B. Pilot burner ignites but will not remain lit when gas valve manual knob is released (Non-CE),
or the pilot button is released (CE).
1. For CE units: Check that thermocouple lead is properly screwed into thermocouple
connection bushing on gas valve.
2. For CE units: Remove end of thermocouple lead from thermocouple connection bushing
and clean with fine sandpaper or emery cloth.
3. Check the thermopile leads where they connect to the gas valve making sure that the
connection is clean and tight.
4. Pilot flame may be too high or too low. Adjust pilot flame adjustment screw so that pilot
flame extends about ¾-inch (22-mm) above the top of the pilot burner.
5. Check all connections for cleanliness and security.
C. Pilot flame of proper size, but is unstable. Flame wavers and does not envelope the
thermocouple completely at all times.
1. Check for drafts that might be caused by air conditioning equipment or make-up air
apparatus. Turn air-moving equipment off and recheck the pilot.
