The Cooling Fan(s) do not Operate
Before you start Put the oven into a heating mode.
WARNING: Electric shock and arc flash hazard.
Use caution when measuring line voltage.
Wear Personal Protective Equipment (PPE).
NOTICE
Do not operate the oven in a cooking mode for an extended
period of time with the service panels removed. Damage to the
electronics may occur without adequate cooling airflow.
An auxiliary fan must be used if the oven will be operated in a
cooking mode for an extended period of time with the service
panels removed.
Measure the DC voltage across terminals 2 and 3 of the P 21
connector on the control board. Is the voltage 12VDC?
No
Replace the control board.
Yes
Measure the DC voltage across terminals + and - of the RL 1
relay. Is the voltage 12VDC?
No
Repair or replace the wires from the
P 21 connector on the control board
to the RL 1 relay.
Yes
Measure the AC voltage across TB 16 and TB 22. Does the
voltage correspond to the voltage printed on the serial
number tag?
No
Reset the circuit breakers. Repair or
replace the wires to TB 16 or TB 22.
CE units—Repair or replace the line
filter.
Yes
Measure the AC voltage across the common terminal at the
RL 1 relay and TB 16. Does the voltage correspond to the
voltage printed on the serial number tag?
No
Repair or replace the wires from TB
22 to the RL 1 relay.
Yes
Measure the AC voltage across the normally open terminal
at the RL 1 and TB 16. Does the voltage correspond to the
voltage printed on the serial number tag?
No
Replace the RL 1 relay.
Yes
Measure the AC voltage across TB 16 and TB 26. Does the
voltage correspond to the voltage printed on the serial
number tag?
No
Repair or replace the wires from the
RL 1 relay to TB 26.
Yes
Measure the AC voltage across the terminals at the cooling
fan(s). Does the voltage correspond to the voltage printed
on the serial number tag?
No
Repair or replace the wires from TB
16 or TB 26 to the cooling fan(s).
Yes
Replace the cooling fan(s).
