STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-69
The fan driver current is too high. This status code will be displayed when the current in
the fan driver circuit exceeds its specific current limit.
The control is reset by recycling the key switch.

Controller
SYMPTOM
Control will not operate.
POSSIBLE CAUSE
· Shorted fan driver coil
· Short between wires connecting to
the fan driver coil.
If the fan driver coil resistance is
correct, then:
· Defective control. Replace
controller unit.

Accelerator potentiometer out of range
(for single accelerator potentiometer
operation).
This status code will be displayed when the voltage at
P7 is greater than 4.13V or less than 0.196V.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
· Defective accelerator pot.
· Measure the voltage from P9 to
NEG. It should be between 4.0 to
4.8V. If it is, replace the
accelerator pot.
· If the voltage from P9 to NEG is not
between 4.0 to 4.8V, remove the wire
from P9 and measure the voltage at
P9. It should be between 4.0 to
4.8V. If it is not, replace the control.
