ENDURANCE SERIES GAS RANGES - SERVICE PROCEDURES AND ADJUSTMENTS
OVEN BURNER NOZZLE AND
ORIFICE CHECK
The oven burner nozzle is mounted between the
oven gas supply tubing and the u-burner assembly.
If burner operation seems poor and other systems
have been checked, remove the burner nozzle and
check for blockage or damage.

If burner operation seems poor and other systems
have been checked, remove the burner nozzle and

1.
Turn off burners and oven.
2.
Disconnect unit from gas flow and allow to cool
completely.
3.
Remove the kick plate as outlined under
COVERS AND PANELS.
4.
Remove the burner nozzle.
5.
Check for blockage or damage.
NOTE: Nozzle blockage can be cleaned or nozzle
replaced. Use high-pressure water and tip cleaner to
clean the nozzle. Replace the nozzle if damaged or
blockage cannot be removed. Check nozzle for
correct orifice size and BTU rating. Use a flow meter
(available from Vulcan-Hart Service Parts Depots,
Part #495) to check BTU rate. See flow meter
instructions for proper installation and use.

CONVECTION OVEN MOTOR
AND DOOR SWITCH CHECK
A control switch mounted just below the convection
oven control valve controls the motor.

1.
Shut off the yellow gas supply knob.
2.
Allow the range to cool completely.
3.
Disconnect electrical power to the range.
4.
Loosen the screws in the sides of the control
valve knobs and remove the knobs.
5.
Remove the control panel mounting screws and
the control panel cover.
6.
Activate the power switch (see illustration)
several times and check for wear, damage, and
loose wiring connections. Repair connections as
necessary.
loose wiring connections. Repair connections as
necessary.
7.
Connect electrical power to the range.
8.
Check power connections for power range (220
volts AC or 120 volts AC).
9.
With the power switch in the ON position, check
for voltage at both switch connections. If no
voltage is available, check power source and
breakers. If voltage is available at switch input
only, replace the switch.

10. If voltage is available at power switch
connections, remove kick plate as outlined
under COVERS AND PANELS.
under COVERS AND PANELS.
11.
Locate the door switch.
12. Disconnect electrical power to the range.
13. Inspect the door switch for wear, damage, and
loose or broken connections. Repair as necessary.
14. Place multimeter in the continuity range. Check
for continuity between the switch connections in
the open and closed position. If continuity is not
available replace the switch.
the open and closed position. If continuity is not
available replace the switch.
15. If continuity is available with switch closed,
connect electrical power to the range.
16. Place multimeter in appropriate AC range (220
volts AC or 120 volts AC).
17. Place the power switch in the ON position.
18. Check for voltage at the door switch input
connection. If voltage is not available,
disconnect electrical power and check continuity
between the motor switch and door switch.
Repair wiring as necessary.

switch (close the door) and check for voltage at
the switch output connection. If voltage is not
available, replace the switch.

available, replace the switch.
20. If output voltage is available, disconnect
electrical power to the range.
21. Remove the cover from the motor electrical
junction box located on the back of the range.
