Tools and Hardware Reviews of Chamberlain WD822KD Whisper Drive 1/2-HP Belt Drive Garage Door OpenerCustomer Review: Excellent product - well made with quality parts, and QUIET Summary: 5 Stars
I used this product to replace an aging chain-drive LiftMaster. Installation was fairly straightforward; it took me about 8 hours total to install (including coffee breaks) and that included some minor adjustments and clean-up (I'm your average Joe - not especially stupid but not an expert in garage door openers either). Because I was replacing an existing door opener I was able to re-use the header bracket supports and (eventually....) the control unit support brackets too. As noted by a previous reviewer, if you're installing from scratch, some of the fasteners needed for installing your own header bracket support and the control unit support brackets are not included in the box - you should plan accordingly and install these items first before attempting the opener install process. The provided installation document is lengthy but has very clear instructions and excellent diagrams.
Once installed, I found most of the factory settings to be exactly what I needed - mine needed very little adjustment in terms of up/down force or travel distance. The unit is very quiet - MUCH quieter than the chain-drive opener it replaced. The safety sensor clamps provided are a breeze compared to older kits I've had to use and they made sensor aligment trivially simple. Everything worked right out of the box - fit and finish of the various components is excellent, a high-quality product. The unit comes complete with two wireless remotes for use in your car(s), a wired switch for operation from inside your garage and a battery-operated wireless keypad device to enter a four digit number sequence. The last device I actually installed inside my home (as I have a detached garage and it made sense for me to do so) - however, it's typically installed directly outside the garage entrance. All of these devices worked perfectly right out of the box.
Although the product per se worked exactly as advertised, I did have some follow-on problems. I own three cars - all of them equipped with HomeLink (the universal garage door opener technology). Previously, each vehicle's HomeLink button was programmed to operate my old LiftMaster and they all worked fine. However, after reprogramming them all to learn the new WhisperDrive's code - none of them worked. I called Chamberlain tech support but they told me flatly that they wouldn't work on any HomeLink issues (even though this product is advertised as being HomeLink-compatible). Instead, they referred me to Homelink for support - which I found a bit annoying. However, the Homelink support line was great and diagnosed my issue in about two minutes: on this model garage door opener, it's not enough to reprogram the Homelink button in each vehicle. You must also subsequently press the "Learn" button on the WhisperDrive's control unit and within 30 seconds press your reprogrammed Homelink button in your car, so that the WhisperDrive can learn that vehicle's new signal. When it has done so successfully it will blink both control unit lights. Repeat this process for each car.
I'd consider this issue to be a Chamberlain problem (it's not documented in the install guide) and not a Homelink problem. Chamberlain's tech support should have been able to handle this one but instead played the finger-pointing game. However, that's a very small nit in what was otherwise a very pleasant(and unexpectedly uneventful) installation experience and a very satisfactory end result.
A very good product - buy it with confidence.
