What Things You’ll need to Adjust Chamberlain Whisper Drive Garage Door Opener? 

This section will cover everything you’ll need to adjust your Chamberlain Whisper Drive garage door opener. The list includes:

  • Screwdriver or nut driver
  • Wrench with a torque setting Adjustment tool
  • Extra strong rope ladder
  • Tester for electrical connections

Steps on How to Adjust Chamberlain Whisper Drive Garage Door Opener

Step 1: Check the Chain Tension

If you can, use a screwdriver instead of any other tool to avoid damaging them. Once you have removed the door from both sides, take a close look at the hinge and identify anything that looks wrong with it. Check the screws and hinges to see if they have somehow been damaged or dislodged from their positions. If you find a screw missing, fix the issue by replacing it with a new one of the same size. You can also check for cracks in the door hinge and other parts to determine whether they need to be replaced.

Step 2: Check the Roller Bracket Adjustment

If the chain is too loose, it’s probably because of something wrong with roller bracket adjustment. So before moving on, we’ll show you how to check and adjust the roller bracket. First, determine if the problem is with only one side or both. If it’s just one side, you must adjust accordingly to that side. If it’s both sides, we’ll show you how to adjust them simultaneously in step four.

Step 3: Check for Bent Rollers

If the chain is too loose, then it’s likely that one or more rollers are bent. For example, the roller may be bent if there was any damage to your garage door while it was installed. You can fix a bent roller by pushing both ends of the roller back into alignment with a hammer and screwdriver. But be careful not to permanently bend the roller, as this could make it difficult or impossible for the chain elevator to pass over the roller.

Step 4: Check and Adjust Both Sides Simultaneously

If both sides of your garage door are too loose, then something is wrong with the bracket adjustment on both sides. To adjust them simultaneously, you’ll need to insert the adjustment tool into a slot in the bracket and then turn it until you feel or hear it click. Before adjusting, verify that the chain is taut by manually pulling up on it with your hands.

Step 5: Check Roller Bracket Tension

With the roller now adjusted, you can go back and check if there is enough tension on the roller bracket. To do this, you’ll need to have another person hold the garage door opener remote and put pressure on the button while manually pulling up the chain with your hands. If it’s too tight, there will be a lot of slack in the chain between it and the roller.  

To decrease the tension, you’ll need to loosen the screw on the bracket. If it’s too loose, there will be very little slack between the chain and roller. So the solution here is to tighten the screw on the bracket, so there’s enough slack between them for proper movement of the Chamberlain Whisper Drive garage door opener chain.

Step 6: Check Fall-Down Prevention and Perform Quick Test

You can then check to see if your Chamberlain Whisper Drive garage door opener is working properly with all of that done. First, test that it’s engaging and disengaging by pressing the remote control button to open and close the door. Next, ensure it won’t fall down with just a little force; try doing this with only one hand holding onto the garage door. And finally, perform a quick test by having someone push the button on the remote while you hold onto the garage door with one hand.

Step 7: Clean Your Chain and Roller Brackets

The final step to ensuring your Chamberlain Whisper Drive garage door opener is working properly is cleaning the chain and roller brackets. To do so, you’ll want to remove the roller by removing screws from the bracket and then cleaning both with a wire brush.

Step 8: Check Other Garage Door Openers

If your garage door opener works fine, then there’s no real reason to adjust it. If not, make sure you’re using the remote control that came with your garage door opener. If you’ve lost it, we recommend using Chamberlain’s Universal Garage Door Opener Remote Control Kit, which includes a receiver and two remotes.

Step 9: Call a Professional for Any Further Assistance

If, after all that, there is still something wrong with your Chamberlain Whisper Drive garage door opener, then there’s likely a problem with your door opener. If this is the case, we recommend contacting Chamberlain or another professional for further assistance.

Step 10: Enjoy Your Smoothly Opened And Closed Garage Door

Now that you’ve adjusted your Chamberlain Whisper Drive garage door opener to work properly, you should enjoy the smooth and quiet movement of your garage door. To keep it from making noise in the future, clean your chain and roller at least twice a month with a metal brush and some light oil on both sides.

Common Mistakes to Avoid When Adjusting Garage Door Openers

  • Don’t forget that the chain needs to be tight if you want your garage door opener to run smoothly. Unfortunately, many people will neglect this and end up with a garage door opener that doesn’t work anymore because they’ve accidentally broken it. 
  • If you don’t have enough force pulling up on the garage door, it’ll be easy for your chain to slip off the roller, which can cause other problems with your Chamberlain Whisper Drive garage door opener.
  • You shouldn’t put too much pressure on your garage door when adjusting it. This is because some Chamberlain Whisper Drive garage door opener models are quite delicate and won’t be able to handle much pressure.
  • Remember that there are two types of chains, single-sided and double-sided, and they have different configurations, so make sure you know which one yours is before adjusting your garage door opener.
  • Instead of trying to pull your garage door all the way up by yourself, use a Tri-lift to do it for you safely and easily.
  • Each time you adjust your Chamberlain Whisper Drive garage door opener, take note of where the screw holes are so that you can move your screws back into the exact same holes next time. This is a great way to ensure that you always have your screws in the right place, and it’ll help you get through the whole adjustment process quicker.
  • Make sure that your chain isn’t too loose, or else it will fall off when your door rises very high, which can cause a lot of damage to other components in your garage door opener.
  • If you don’t have enough tension on your springs and they’re not tight, then it’ll be easy for the chain to come off of one of the rollers, which can cause all sorts of problems with your Chamberlain Whisper Drive garage door opener.

Frequently Asked Questions

How To Determine Chain Drive systems on Chamberlain Openers?

There are two different Chain Drive systems used on Chamberlain Openers. You can determine which one you have by looking at the chain used to drive your door. Then, dig a little deeper and look at the side of your garage door opener casing itself. If it has an Am-Esk or Am-Ket Crest logo, it runs on a Chain Drive System manufactured by the Chamberlain Company.

If your opener has a black and gold logo on the front of its case, it is running on a Chain Drive system manufactured by Black & Decker. Unfortunately, this chain drive system does not lend itself to upgrading in this manner – you can only reduce the size of the sprockets using a Sawzall or equivalent. The good news is that the Chain Drive systems manufactured by Black & Decker are quieter.

How Can I Program My Chamberlain Whisper Drive Garage Door Opener?

To program your Chamberlain Whisper Drive garage door opener, you’ll have to follow the instructions that are included with your specific model. If no programming sheet is available with your garage door opener or if you’ve misplaced it, then go online and try downloading a manual from Chamberlain’s website.

If this doesn’t work or you don’t want to wait for your manual to be mailed out, call Chamberlain and ask them to help you with the programming.

Can I Make My Garage Door Open Higher?

Yes, you can make your garage door open higher by following these simple steps:

1. Locate the tension cable on the opener and remove it from the arm.

2. Disconnect the two wires from the arm and secure them to a terminal on your electrician’s panel.

3. Reconnect the tension cable to the arm and tighten it with a wrench or pliers.

4. Test your new height by raising the garage door manually and verifying that it moves at the desired height.

Can You Change the Sensitivity on a Garage Door Opener?

Yes, you can change the sensitivity on a garage door opener. This is done by adjusting the micro switch. There are two types of microswitches: fixed and variable.

A fixed microswitch does not allow you to adjust the sensitivity; it is either on or off. A variable microswitch allows you to increase or decrease the sensitivity, but it cannot be turned off.

To adjust the sensitivity on a fixed microswitch:

1) Open the garage door using your remote control.

2) Raise the arm of the opener until it is in its highest position (the “up” position).

3) Look for a small white plastic switch on one side of the arm. It will have a black knob on it.

4) Turn the black knob to increase or decrease the sensitivity of the micro switch.

Why Is My Garage Door Opening Very Slowly?

There are a few things that can slow down your garage door, including:

  • Weather conditions.
  • Age and condition of the garage door opener.
  • Size and weight of the object being transported.
  • Garbage or leaves in the garage.

Can I Speed Up My Garage Door?

Yes, you can speed up your garage door by following these simple steps:

  1. Clear the area around the garage door to ensure there are no obstacles in the way.
  2. Locate the belt and pulley system.
