The Smoke Function does not Operate
WARNING: Electric shock and arc flash hazard.
Use caution when measuring line voltage.
Wear Personal Protective Equipment (PPE).
Is the smoke icon available to be selected on cook
screen?
No
Check dipswitch settings on the control board.
Dipswitch 4 needs to in the ON position. Cycle
power to the oven after setting dipswitch. If the
icon is now able to be selected, but the oven
does not smoke, continue with the
troubleshooting tree.
Yes
While the smoke element is activated, measure the
current draw of the smoke element at RY2-1. Do you
read any current draw?
No
Smoke element should be making heat.
Yes
Disconnect smoker element wires and measure the
resistance of the smoke element. Does the element
read OL?
No
Replace smoke element.
Yes
While the smoke element is activated, check the AC
voltage supplied to the smoke element. Do you have
line voltage?
No
If still no LED, replace the control board.
Yes
Measure the AC Voltage supplied to the smoke relay
on the control board in reference to a known neutral
or L2. Do you have line voltage coming into the smoke
relay on the control board?
No
If you have L1 coming into the relay, but nothing
out when the relay is activated (LED illuminated),
the relay is faulty. Replace the control board.
Yes
Measure the AC Voltage between TB3 and TB4. Do
you have line voltage?
No
Inspect and repair the wired connections.
Measure the incoming voltage to the smoke
relay.
Yes
Measure the AC Voltage between TB1 L1 and TB1 L2/
N. Do you have line voltage?
No
Inspect and repair the wired connections.
Measure the incoming voltage to TB3 and TB4.
Yes
Check circuit breakers. Are either tripped?
No
Reset circuit breakers and retest incoming
voltage to TB3 and TB4.
Yes
Measure the AC voltage between both circuit
breakers. Do you have line voltage?
No
If you have line voltage on the incoming side of
the circuit breaker but not on the outgoing,
replace the circuit breaker.
Yes
