The following troubleshooting information includes
checking procedures for various electrical components
in order to help identify faulty components. The
troubleshooting guide below is designed to identify
various symptoms and provide the suggested remedy.
COMPONENT CHECK PROCEDURES
Checking the Power Switch
The Power Switch has a built-in LED that lights
red when the switch is in the on position. Check the
following before replacing the switch.
• Make sure the power cord is plugged into the correct
receptacle. The broiler operates on 120VAC 60Hz
line current.
• Check the circuit breaker assigned to the broiler.
• Try a different receptacle before replacing the
switch.
• It’s possible for the LED in the switch to fail. Turn
the switch on and check the Control Board display.
If the display is active, the LED is burned out,
replace the switch.
Checking the Control Board
Under normal conditions, the Control Board displays
the current status of the broiler. It can be used as a
diagnostic tool, when it is working properly.
Try the following before replacing the Control Board.
• Cycle the broiler off and on; observe the Control
Board.
• Try running the Control Board through a couple
of different cook cycles.
NOTE: If the Control Board is still not performing
properly, try these procedures:
1. Turn the broiler off.
2. Remove the Control Board.
3. Check each connection on the back of the Control
Board. Make sure they are all connected correctly.
4. Loosely attach the Control Board, turn the broiler

on. Observe the display and product key LEDs.
5. Turn the power off and reattach the Control Board

Checking the Conveyor Drive Motor
The Conveyor Drive Motor is located on the front of
the broiler on the lower discharge side. Before replacing
it, check the Conveyor for jammed meat product.
Next, try turning the Conveyor discharge shaft with
the Multipurpose Broiler Tool. If the Conveyor does
not turn, check the following items:
• Check the Discharge Chute.
• Check the Loader Ramp.
• Check the Ash Scraper.
• Check the Cook Chain (Conveyor).
• Check the Flame Arrestor.
Testing the Conveyor Drive Motor
The Conveyor Drive Motor may be tested without
removing it from the broiler.
