SERVICING GUIDE
This section contains servicing information intended for use by Authorized Service Personnel. If Fault Isolation Procedure
is required, be sure to start at step #1.
A/Problem: Skillet is not heating at all. (Skillet must be on, in a down position and
thermostat control set).
Possible Causes
1. No power — either gas or electric. 8. Defective pilot flame sensor.
2. Micro (cut-off) switch faulty or not activated 9. Defective pilot re-light.
(skillet in a tilted position). 10. Defective cycling pilot safety timer.
3. Defective on/off switch. (Spark ignition)
4. Defective control thermostat 11. Defective or incorrectly adjusted gas
5. Defective safety thermostat control valve.
6. Defective 208-240/120 VAC transformer. 12. Blown 4/10, 1 1/2, or 10 amp fuse.
(208-240V units) 13. Incorrect spark gap-(Spark ignition)
7. Defective 120/25 VAC transformer. 14. Poor ground.
15. Faulty wiring.

It is assumed that there is proper operating incoming gas pressure of minimum 7" WC for natural gas and 12" WC for
LP gas. For manual ignition, go to step #10. For spark ignition natural gas, go to step #12. For spark ignition LP gas, go
to step # 17.

adjust flame if necessary. If adjustment is not
required or unsuccessful, go to step #11.
No Replace defective gas control valve.
11. Does the pilot flame sensor (thermopile) generate
450-750 mV? Yes Replace defective gas control valve.
No Replace defective pilot flame sensor.
12. Look through peep hole. Can a pilot flame be
achieved? Yes Go to step#16.
No Go to step # 13.
13. Is a spark being generated? Yes Go to step#15.
No Go to step # 14.
14. Is the spark gap 1/8" ± 1/32"? Yes Replace defective pilot re-light
No Adjust spark gap.
15. Yes Replace defective gas control valve. Measure continuity across pilot flame sensor's
pins #3 and #4. is it a closed circuit? No Replace defective pilot flame sensor.
16. Yes Replace defective gas control valve. After pilot has been lit for 5 minutes, pull pilot
flame sensor's connection off and quickly
measure continuity between pins #2 and #4.
Isit a
closed circuit at first and after pilotflame sensor
cools down the circuit opens?
No Refer toPilot Flame Adjustment Procedure and
adjust flame if necessary. If adjustment is not
required or unsuccessful, replace defective pilot
flame sensor.
17. Yes Go to step # 19. Look through peep hole-Is a spark being
generated? No Go to step # 18.
18. Is the spark gap 1/8"± 1/32"? Yes Replace defective pilot re-light
No Adjust spark gap.
19. Yes If burners now fail to ignite, go to step #21. Turn power on/off switch to "off" for 5minutes.
This wit! zero the cycling pilot safety timer. Then
turn unit back on. Is a pilot flame now available? No Go to step # 20.
20. Measure continuity across pilot flame sensor's
pins #3 and #4.Is it a closed circuit? Yes
Replace either defective cycling pilot safety timer or
gas control valve. (Note: Gas control valve would
be the more reliable component)
No Replace defective pilot flame sensor.
21. Yes Replace defective gas control valve. After pilot has been lit and just as pilot goes out
due to cycling pilot safety timer, pull pilot flame
sensor's connection off and quickly measure
continuity between pins #2 and #4. Is it a closed
circuit at first and after pilot flame sensor cools
down the circuit opens?
No Refer toPilot Flame Adjustment Procedure and
adjust flame if necessary. If adjustment is not
required or unsuccessful, replace defective pilot
flame sensor.
16

B/Problem: Skillet heats too slowly or not hot enough. (Note: Maximum surface temp. is 425°F).
Possible Causes
1. Low incoming gas pressure.
2. Detective or incorrectly adjusted gas control valve.
3. Detective or incorrectly adjusted control thermostat.
4. Detective or incorrectly adjusted safety thermostat.
Fault Isolation Procedure
Step Test Result Remedy
1. Yes Go to step # 3. Tilt skillet fully forward and manually activate the tilt
safety switch. Inspect the burner flame for a period of
4or 5 minutes, Is the burner flame strong and
constant? No Go to step # 2.
2. There is an operating gas supply problem. either
incoming or outgoing. Refer to Pilot Flame
Adjustment and Gas Pressure Adjustment Procedure.
If this does not correct the problem, check incoming
operating gas supply. It should be minimum 7" WC
natural gas or 12" WC LP gas. If gas pressure is
correct, replace defective gas control valve.
3. Yes Go to step # 4. In an operating situation and with control thermostat
set at #10, does the operating (upper) pilot light go
out too early? (Burners shut off too early) No Go to step # 2.
4. Yes Adjust or replace safety thermostat (adjust to470°F) Immediately after operating (upper) pilot goes out,
turn control thermostat to#1.
Can you hear or feel the
thermostat "clicking" off? No Adjust or replace control thermostat (adjust to approx.
425°F)
C/Problem: Skillet is overheating.
Replace or adjust control thermostat (adjust to approx. 425°F)Verify that the safety thermostat shuts off
at approx. 470°F.
17

D/Problem: Skillet fails to tilt (Power tilt units) (Note: A thermal overload in jack motor does not allow
constant consecutive tilting)
Possible Causes
1. No electrical power to the skillet.
2. Defective rocker (up-down) switch.
3. Detective start capacitor.
4. Blown 10 amp fuse. (208-240V units)
5. Detective 208-240/120 VAC transformer. (208-240Vunits)
6. Detective power jack.
Fault Isolation Procedure
Step Test Result Remedy
1. Is there electrical power to the skillet? Yes Go to step #2.
No Correct external power supply problem.
2. Yes Replace blown fuse. On 120V units, go to step#4. On 208-240V units, is
either one of the 10 amp fuses blown? No Go to step # 3.
3. Yes Go to step # 4. Is there 120 VAC present at output of 208-240/120
VAC transformer? No Replace defective 208-240/120 VAC transformer.
4. Yes Go to step # 5. Test rocker switch for continuity. Is it operating
properly? No Replace detective rocker switch.
5. Yes Replace defective power jack. Remove motor from power jack. Activate tilt switch.
Does the motor rotate? No Go to step # 6.
6. Yes Replace defective start capacitor. Remove power jack wiring from connections-Measure
resistance across each of the three wires. Do they read
(approx.) 14 ohms between black and white, 29 ohms
between black and red, and 14 ohms between red and
white?
No Replace defective motor.

GAS PRESSURE ADJUSTMENT PROCEDURE
CAUTION: The following procedure, as well as other work on gas controls should be
performed only by a qualified service technician.
NOTE: Gas pressure adjustment is pre-set and rarely needs any adjustment
1. Remove gas pressure adjustment cover screw.
2. Operating gas pressure output should be regulated to 6" W.C. natural gas and 11" W.C. LP gas.
3. Turn gas pressure adjustment screw (under cover screw) clockwise to increase or
counterclockwise to decrease gas pressure.
4. Replace cover screw.
PILOT FLAME ADJUSTMENT PROCEDURE
CAUTION: The following procedure, as well as all other work on gas controls should
be performed only by a qualified service technician.
1. Remove pilot adjustment cover screw.
2. Turn pilot flow adjustment screw (under cover screw) clockwise to increase flame (see
below drawing for correct flame adjustment).
3. Replace cover screw.
