8. Control board 15
amp fuse blows
when Open/Close
command is given.
1. Fuses blow primarily for one reason, the gate cannot move. Causes
might be something keeping the gate from moving, the gate is trying
to move in the wrong direction due to incorrect limit switch setting or
there might be a wiring problem. A wiring problem is most likely in a
splice that might have been made during installation or it could be in
the actuator housing.
2. Open the control box and locate the Patriot control board, locate the
2 LED’s under the actuator connector on the control board. Press
the “LED Indicator” push button and hold it in, observe the LED’s
and determine if the retract limit or extend limit LED is on. Then
determine if the correct LED is on for the gate position. For example
if the left LED is on that is the retract limit and the actuator should be
in the retracted position. The right LED represents the extend limit
position.
3. If the retract limit LED is on and the actuator is extended, a
command to operate the gate will try to extend more, which can blow
a fuse. If the extend limit LED is on and the actuator is retracted,
a command to operate the gate will try to retract more, which can
blow a fuse. In either case, the limit switches need to be adjusted
and then the cause for them becoming misadjusted needs to be
determined. The cause generally has to do with wiring; bad actuator
plug connection at the Patriot control board or too much adjustment
has been made during installation. Limit switches also get out of
adjustment if the actuator runs while disconnected from the gate.
4. If a wiring problem is suspected, the orange, white and green wires
are the ones to concentrate on. Check all splices and verify actuator
connector is connected at the control board.
5. If the actuator is suspected of being bad either due to an internal
wiring problem or a motor problem, call the factory for further
troubleshooting and return information.
