Followed the warranty process to the letter (return authorization directly from Liftmaster, telephone and email correspondence with Gatecrafters), returned to gatecrafters for refurbishment using their mailing process) then nothing. Frustrated calls, emails, etc were met with excuses (eg, "factory was between model runs, etc", or "we will get to it right away"), then no responses at all. Calls go unanswered. Beyond frustrating. I would have pursued local repair if I knew they were not going to return the product I sent. So, now I'm out the money ($700) AND dont even have the option of getting someone to fix it. All while under Liftmaster's warranty window. This company may be the most disorganized mess I've done business with.
