CORRECTIVE ACTION
If a High Frequency unit is being
used, make sure it is connected
properly. There may be high fre-
quency intrusion from another
source in the immediate area.
Remove all possible forms of RF
intrusion.
If the problem persists, the
control board may be faulty.
Check for proper selector
switch/handle alignment.
Check the selector switch and
associated wiring. See the Wiring
Diagram. If the problem persists,
the control board may be faulty.
