DIAGNOSIS & TROUBLESHOOTING

DIAGNOSIS

FAILURE/ERROR DISPLAY CODES TECH SHEET #9753028, REV. B

All diagnoses of this range must begin with a normal check of the line voltage, blown fuses, and failed components.

All units that have failed during the first few days of use should be checked for loose connections, or miswiring.

All checks should be made with a meter having a sensitivity of 20,000 ohms-per-volt, or greater.
