SERVICE
PART FAILURE VERIFICATION
CONTROLS AND ASSEMBLIES
All attempts have been made to provide solid information and techniques to verify that a suspect part has in fact
failed. We are committed to providing the absolute best possible service to our customers throughout the life of
their product.
1. Visually inspect the switch for damage.
2. Observe the mechanical function and snapping action to the ON and OFF position.
3. Disconnect the wires to a minimum of 1 terminal. Use an Ohm meter to verify the closed
contact (switch ON) is less than 1 Ohm and that the open contact (switch OFF) is an open
load (OL).
4. Replace the switch if mechanically or electrically damaged.
SWITCHES
1. Visually inspect the breakers for damage.
2. Use an Ohm meter to verify that the breaker measures less than 1 Ohm.
3. Replace the breaker if mechanically or electrically damaged.
BREAKERS
1. The fan power connector can be pulled out slightly, allowing meter leads to access the
terminals.
2. Measure the voltage on these terminals. If MAINS voltage is present and the fan is not
spinning, replace the cooling fan.
COOLING FAN
1. If the transformer is suspected, test the windings before powering the oven. The
secondary (yellow/blue wires) of the transformer will measure between 0.5~2 Ohms. The
primary black/white wires (120V) or black/orange (240V) of the transformer will be 10~30
ohms.
2. If either winding is OPEN or SHORTED, replace the transformer.
TRANSFORMER
The Induction Blower/Fan should spin freely and ramp to high speed when line voltage is
applied.
1. If the motor rotates roughly, has excessive drag, or fails to start when voltage is
applied, replace the motor.
