The Wall Switch and Remote Control Can’t Operate the Opener

If you are experiencing problems with your garage door not opening when you press the remote or wall switch, then the issue could be the power source. It is possible that there is a disruption in the power source. For this issue, check if the motor unit is plugged or unplugged. See to it that the cord has been plugged thoroughly all the way. 

Other possible culprits in this problem are the GFCI, fuse, or circuit breaker. These things control the garage door opener circuit. You need to check if they have been burned out or tripped. To do this, check the other electrical circuits or lights in your garage and see if they are working well. If they are not, then this might be the cause. 

To remedy this problem, reset the GFCI or breaker. You will also need to replace the fuse that has been burned out. Try to observe if the GFCI or circuit breaker has been repeatedly tripping. It is because it could be a sign that somewhen in your system, there’s a short circuit. 

Lastly, the motor of the garage door opener may have burned out that’s why it’s not functioning anymore. If this is the case, then the next thing you should do would be to call a garage door repair service so that they can replace the motor. 


The Garage Door is not Responding to the Remote Control 

If this is the problem of your Chamberlain garage door opener, then there are several solutions that you can try to make them work again. 

The first thing you can do is to move closer towards the door. Maybe you are simply out of range. Today’s garage doors operate at somewhere about 315mH. It means that just a few feet away from the range can greatly affect the signal. 

If that doesn’t solve the problem, then make sure that the motor unit’s antenna hangs downward. Also, check if the antenna has been damaged in any way. Another way to fix your Chamberlain garage door opener is to see if your door works just fine using the wall switch. If this is the case, then maybe the remote’s batteries need replacement. 

You may also reprogram your garage door remote. It has sensitive electronics inside so it is possible that the programming has been lost and only needs to be reset. Remember though that every garage door opener will be different when it comes to reprogramming it. It is best that you check the instructions first. To be sure, you can do a quick search online for the procedure for your specific opener.

Garage Door Won’t Completely Open

When your Chamberlain garage door opener causes your garage door to open but only partially, then there may be two likely causes to it. The first one is that you may need to move the up-limit switch closer to the motor unit. 

This particular switch is a touch-lever that is mounted near the motor unit around the end of the track. If the switch is far, then the motor will not continue to open the garage door fully. 

The best solution here is to move that switch nearer to the motor unit. This kind of problem is not that common. But if it is the case, then you can follow these tips and check if it will make the garage door open fully. 

The second cause of why the garage door won’t completely open would be damaged rollers. Inspect the rollers if there is any damage. You can then lubricate the ones that are already rusty. That should do the trick and you’ll be able to have your garage doors open completely.
