Gen 3: Run Float Switch Diagnostic

Confirm the current position of the float switch

• MTCE Menu, FLT
• “dn” indicates float is in down position.  “UP” indicates float is in up position.
• After mist cycle and batch makeup, FLT should display “UP.”

Confirm the float switch is working

• Remove controller from cavity in shroud so that you can manipulate float in batch tank.
• MTCE Menu, FLT
• With your hand, move the float position from down to up and confirm correct position is displayed by controller.
• If display does not reflect float position, ensure secure connection to wiring harness and repeat diagnostic.
• If display still does not reflect position, it is likely that float has failed and requires replacement.  See Gen 3:  Clean or Replace Float Switch.
