To avoid electrical shock or moving parts hazards when covers are removed for troubleshooting, wait 45 sec- onds after unplugging power cord for stored electricity to dissipate. Keep clear of electrical and moving parts during troubleshooting procedures.

If no digital display is available, use the con- trol board status light to troubleshoot prob- lems. turn ON/OFF switch to OFF, remove control cover and then turn power back ON. Observe status light. Blinking LED total count equals digital error code (example: two blinks equals E=02).
