DIAGNOSIS & TROUBLESHOOTING
DIAGNOSIS
• 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.
FAILURE/ERROR DISPLAY CODES
• All diagnoses of this range must begin with a
normal check of the line voltage, blown fuses,
and failed components.
