or damaged
Check cable between
receiver and powerhead
main board for
disconnection or damage
to the cabling.
Correct any issues or replace
any faulty parts.
Firmware glitch
or transient
condition
Power cycle the operator
completely. If the power
cycle does not resolve
the issue, restore factory
defaults settings and
recongure the operator.
If the steps listed in the
diagnosis resolve the issue,
there may have been a
transient condition that
caused and issue that was
resolved. If the issue occurs
excessively, the problem may
lie elsewhere.
Bad receiver
module or bad
powerhead
main board
Replace the receiver
module with a known
good unit.
If the problem is resolved,
replace the receiver with a
new one.
If the known good unit still
does not work, replace the
powerhead main board.
Other bad

Temporarily remove
other accessories from
between the wireless

If issue is resolved, add
accessories back one by
one to nd the accessory
that causes the issue, then
troubleshoot that device
