Replacing Your Circuit Board on Most Garage Doors

You push the button on your garage door opener and nothing happens. You’ve checked the power to the outlet. You’ve even put fresh batteries in the remote. And still, nada. The most likely culprit is a bad circuit board. Strangely, this is often caused by lightning strikes.

Fortunately, replacing a circuit board is a fairly easy garage door repair to do yourself. You’ll need to purchase a new board and install it. We’ll walk you through it. It takes about 10 minutes, and all you need is a new board and a ¼ inch nut driver.

But First – Have You Checked the Power Supply?

Of course before you start replacing the circuit board, you should first check to see if it might be a battery or power supply issue. Yes, your garage door repair problem could be this simple.

You’d be surprised how many emergency garage door repair calls we get that turn out to be nothing but a set of bad batteries. It’s so common that we make sure all of our response trucks are stocked with fresh batteries.

Power is an issue that’s easy to overlook. Switch out the batteries in your remote. Check to make sure the garage door opener is plugged in. Take a look at the circuit box to see if you’ve blown any fuses. If your garage door opener plugs in, make sure the socket is connected.

Replacing the Garage Door Opener’s Circuit Board

Once you’ve determined there’s no good reason your garage door shouldn’t be working, it’s time to head to the hardware store and get yourself a new circuit board. A new garage door opener circuit board and surge protector will run you less than $100.

Now, replacing the circuit board is super easy:

  • Remove the light cover and light bulb.
  • Disconnect the switch and safety sensor wires.
  • Remove a few screws.
  • Reapply the new board.
  • Put everything back together.

You’re done! Congratulations.

But wait… what if this new circuit board hasn’t fixed the issue? Well, since you already confirmed power’s good, and now you know for a fact the circuit board is, the issue is likely the motor.

How to Replace Your Garage Door Opener Motor

This repair is a bit more involved, but still well within the do-it-yourself range of garage door fixes. If your garage door motor no longer seems to be working, it may need to be replaced. You can purchase a new motor assembly kit for your opener online, or check with your garage door company. For a 2-car garage, you’ll probably need a ½ HP motor. If you’re wondering what’s best to choose, give us a call for a professional opinion!

Once you’ve got your motor, the rest is simple – it’s just like a little 3D puzzle:

  • With the door in the closed position, disconnect the power to the garage door opener. All you need to do is unplug it.
  • Disconnect the motor and loosen the chain.
  • Take the cover off the opener by removing the screws that hold it in place.
  • Take a look at the white gear, your motor, and how it is connected to the unit. You’ll need to connect the new gear the same way.
  • Disconnect the RPM assembly and the motor, unscrewing the screws that hold it in place.
  • Attach the new motor in the same way, retracing your steps.
  • Attach the wires to the appropriate connections. Reattach the motor’s cover.
  • Oil all moving parts.

Congratulations! You just DIY repaired your garage door opener motor.

Have You Checked Your Battery Backup Lately?

While we’re already on the subject of tuning up our garage door opener and troubleshooting power issues, let’s check on the battery backup. Your opener will either have an integrated one, in which case it will be labeled “battery backup,” or you may have an add-on garage door battery backup, which will be its own unit.

LED lights let you know when your opener’s backup battery is charged, charging or dead. You can test the battery simply by unplugging your garage door opener and then trying to use it. It’s a good idea to do this every so often, as you don’t want to hit an emergency and find out you may as well have never had a battery backup at all.

Keep in mind that your garage door opener’s backup battery will need replaced every 12 to 24 months.
