Inside the encoder box is a photoelectric sensor. As the magnet rotates it counts the rotations and sends that information to the control unit.

This is how the control unit measures the distance that the doors slide open or shut. It is very rare that the encoder ever goes out. Although it may be a popular repair to do, because it is so easy, many times the repair can be avoided all together. If your Stanley MC Pro reads a b1 error, turn the power off to the door opener. Unplug the encoder plug from controller. Plug it back in. Make sure it is secure. It is very common for the encoder plug to not get plugged in all the way causing a b1 error.

It is also common that the encoder wire harness may have gotten snagged by the moving timing belt. Analyze the encoder harness and make sure it is not damaged in any way. Turn the power back on the door, and see it it runs normally.

Another common way to get a b1 error is if the timing belt is too loose. The door may slam shut or open, because the door controller thinks the door panels are only half open, when they are actually full open with no distance left. When this happens and the door slams, you will get b1 encoder error.

To solve this you would need to perform a new first install sequence FIS. Fix 3 0b Obstruction Error The 0b error code means obstruction. To solve this turn the door off. Then check the door track and make sure there are no rocks or obstructions. Make sure the bottom track plastic insert is operational and not damaged. Slide the door panels fast and slow.

It is very common for the bottom guides to have failed rollers or a sticky bottom guide shaft which can obstruct the door. Push up and down on the bottom guide forks at the bottom of the heel of the moving door panel. The bottom fork guide should move up and down.

If it moves up and sticks, and does not come down, then your bottom guide is defective, and is causing the obstruction. Also check the top rollers, make sure that each roller has a functional bearing and rolls smoothly. It is always wise to replace the bottom guides with the top rollers at the same time to reduce any chance of future failure.

Fix 4 20 Breakout Error The 20 error code means breakout. This indicates that one of the door panels is swung out. With the door off, swing open each door panel and firmly snap it back in. Turn on the door. If the error is still there, check the breakout switches. You will either need to re-adjust them, or replace them. Confirm that the photocells in the door stiles are functional and not damaged.

Check the safety beam control board. On the safety beam control board is an led. When the safety beams are not activated, there should be no light on. When the safety beam is triggered the led should light up.
