If The Reverse Sensor Adjustment Is Broken Is It Replaceable?

I have an Elite Miracle One gate opener from 2001 with upgraded board from 2013. The gate will move only a bit and then stops. The reverse sensor light then turns on. This happens in either direction. The sensor screw offers little resistance when turned and has no stop, so I cannot reduce the sensitivity. My guess is that I broke it when adjusting the sensitivity recently. The gate moves easily when the drive is unlocked. Everything is well lubricated and level. Is this part replaceable? Would I have to get a new board (which probably means a new opener and the model is so old)? Any other way to confirm this is the cause or is the light and the lack of a stop sufficient evidence..

REPAIR MALFUNCTIONING GARAGE DOOR SENSOR

It sounds like you may have damaged the sensor on your Elite Miracle One gate opener. The sensor is responsible for detecting objects in the path of the gate and stopping the gate if necessary. If the sensor is damaged, the gate will not be able to close properly and may even reverse direction.

The sensor is a replaceable part, and you can find replacement sensors for Elite Miracle One gate openers online or at some hardware stores. To replace the sensor, you will need to disconnect the power to the gate opener and remove the old sensor. The new sensor will come with instructions for installation.

If you are not comfortable replacing the sensor yourself, you can call a qualified technician to do it for you.

Here are some other ways to confirm that the sensor is the problem:

Check the sensor wires to make sure they are not damaged.

Try adjusting the sensitivity of the sensor. If the gate still stops after adjusting the sensitivity, then the sensor is probably damaged.

You can also try shining a flashlight at the sensor while the gate is moving. If the gate stops, then the sensor is working properly. If the gate does not stop, then the sensor is damaged.

If you have confirmed that the sensor is damaged, you will need to replace it in order to get your gate opener working properly again.

THE HARD TEST: Feeling handy after that first test? If you still haven't identified the problem or if you want to test the sensor wires themselves...
  1. Remove the sensors from the brackets.
  2. Remove the wires from the wire nuts or cut the sensor wires 12R43; from the sensors.
  3. Strip both ends of wires from each sensor and twist like colored wires together. Proceed with both sensors to the garage door opener motor unit.
  4. Remove existing wires from the white and grey terminals on the back of the operator.
  5. Attach or insert white wires into the white terminal and black/white striped wires into the grey terminal.
  6. Point the sensors at each other - if both sensor LED's turn on, there is an issue with your wiring. Replace the wires between the opener and the sensors. If the LED's DO NOT turn on, replace the sensors.

If you've gone through these tests and are still stumped as to what the problem could be - or if you just don't want to deal with it - give us a call.
