Any upper control which does not pass the preoperational inspection criteria found in the Operator’s Manual must be removed from service and replaced. Customer Action: Continue to perform preoperational inspections, including testing upper controls for normal operation. Any upper control which does not pass the preoperational inspection must be removed from service and repaired. All upper controls on the affected units, regardless of functionality, must be inspected for potentiometers from the suspect Lot.
