Replacement Instructions for Limit Switch Assembly 41D4671

You will need a 1/4" magnetic nut driver.

1. Fully close the garage door.

2. Disconnect power to the opener.

3. Remove the opener lens (refer to your owner’s

manual).

4. Remove the cover:

• Using a 1/4" magnetic nut driver, remove the two

screws recessed in the bottom of the cover.

• Unplug the wires to the light sockets inside, and

place the cover aside.

5. Lift off the control center access door and set aside.

6. Unfasten the receiver logic board assembly from the

chassis by removing the two screws inside the panel

under the top edges . Allow it to hang suspended(a)

by wires.

7. Disengage the limit switch assembly from the(b)

retention slots in the limit switch bracket (c) by

squeezing the top and bottom on the right near the

drive gear (see illustration).

8. Disengage the hook on the left and allow(d)

assembly to hang by wires.

limit switch and reconnect them to the new

assembly.

reassemble the unit.

The garage door MUST be in the fully closed position during

installation.

CAUTION

CAUTIONCAUTION

Testing the Safety Reverse System:

TEST:

• With the door fully open, place a 1-1/2" (3.8 cm) board (or a

2x4 laid flat) on the floor, centered under the garage door.

• Operate the door in the down direction. The door must

reverse on striking the obstruction.

ADJUST:

• If the door stops on the obstruction, it is not traveling far

enough in the down direction. Increase the DOWN limit by

turning the DOWN limit adjustment screw counterclockwise

1/4 turn.

NOTE: On a sectional door, make sure limit adjustments do

not force the door arm beyond a straight up and down

position.

• Repeat the test.

• When the door reverses on the 1-1/2" (3.8 cm) board,

remove the obstruction and run the opener through 3 or 4

complete travel cycles to test adjustment.

• If the unit continues to fail the Safety Reverse Test, call for

a trained door systems technician.

IMPORTANT SAFETY CHECK:

Test the Safety Reverse System after:

• Each adjustment of door arm length, limits, or force

controls.

• Any repair to or adjustment of the garage door (including

springs and hardware).

• Any repair to or buckling of the garage floor.

• Any repair to or adjustment of the opener.

1-1/2" (3.8 cm) board

(or a 2x4 laid flat)

Without a properly installed safety reversal system, persons

(particularly small children) could be SERIOUSLY INJURED or

KILLED by a closing garage door.

• Safety reversal system MUST be tested every month.

• If one control (force or travel limits) is adjusted, the other control

may also need adjustment.

• After ANY adjustments are made, the safety reversal system

MUST be tested. Door MUST reverse on contact with 1-1/2" high

(3.8 cm) object (or 2x4 laid flat) on the floor.
