4. If the belt/deck was replaced, remeasure the AC input current. Damage to the MC
1
motor control module can occur if the machine has been operated in an overload/high
current condition for prolonged periods of time. This type of damage would not gen-
erate an error code but would cause the breaker to trip intermittently. Measuring the
AC input current draw will verify the condition of the MC: a high AC input current draw
or intermittently tripped ON/OFF circuit breaker indicates that the MC is damaged.
NOTE: Damage to the lower control module can occur if the unit had been run in an
overload/high current condition for prolonged periods of time. This type of damage
would not generate an error code but would cause the breaker to trip intermittently.
An amp draw test will verify this condition.
