Garage Door Corporation has now had several Liftmaster model 8550w Myq belt drive with battery backup and wi-fi which are not recognized by the Liftmaster MyQ servers. The problem is that when a customer tries to setup MyQ for smart phone access (Android, IPhone, browser) one of the first steps after creating the online account is to enter your MyQ serial number. The Liftmaster server reports that it does not recognize the serial number entered. After checking with Liftmaster support in Tucson, AZ it was determined that this is a known problem which they are trying to resolve.
Garage Door Corporation has received numerous customer calls regarding the MyQ false push notifications 4/28/15. Liftmaster reported on 4/28/15 via email that they were aware of the problem and subsequently issued the comment below to explain the problem:
Don't be surprised if you visit liftmaster.com which redirects to https://www.liftmaster.com and you do not get a SSL padlock in your browser.

Liftmaster is using SSA-1 which is being deprecated and their SSL certificate expires in 2017. This certificate was issued 07/2014 after it was well documented that SHA-256 needed to be used!
Garage Door Corporation receives calls on a regular basis from customers seeking a new remote for their Intercontinental Dynamics ESP Micom remote control transmitter (usually model T-9) and occasionally a M-9 receiver. The manufacturer has been out of business for over 20 years. There has been one after market clone transmitter but we have found it to be highly unreliable and poor quality. The universal remote controls (ie Clicker Corporation or Liftmaster 385LM) will NOT work with an ESP Micom receiver.
Garage Door Corporation has been advised that some LiftMaster garage door openers (models 1355, 3255, 3270, and 3265-267) manufactured between January and March, 2014 may be generating a higher amount of sound than normal from the powerhead. LiftMaster testing has shown that only a small percentage of these garage door openers vibrate more than LiftMaster finds acceptable. To correct this issue, LiftMaster has designed and tested a Chassis Bracket which an installer can attach to a unit that they determine is experiencing above normal sound levels.
Every year about this time we see a sharp increase in the number of drive gear and sprocket failures in garage door openers. We have customers asking "Can I get just the large plastic gear by itself?" Most of these customers have seen "cheap" aftermarket gears on the internet. Many of these gears are made in Venezuela or other aftermarket sources and include just the large gear and not the drive gear on the motor shaft. These will work for awhile but if put any value on your time you should always change both gears at the same time and be sure to lubricate them well.
Garage Door Corporation has received the pdf versions of the new Liftmaster 8355 model literature and owners manual. These are both available on our website at www.gdcorp.com Literature is available on our home page and the manual is on the instructions page (click the link near the top of our home page). We expect stock on the new model next week and still have some model 3280 belt drive openers for sale. See our previous post about the additions and changes for this new model.
Garage Door Corporation has received an official announcement from Liftmaster (by Chamberlain) that the model 3280 1/2hp belt drive garage door opener has been discontinued. Rumors of this have been circulating for awhile but as seen below it is not official. In a move towards expanding the MyQ product line Liftmaster has replaced the model 3280 with the model 8355 which is a 1/2 hp belt drive with MyQ. The model 3280 was our most popular model since it was quieter than the chain drive (ie model 3255 or 3265) and was priced competitively.
