My garage door opener unit was having trouble. The logic board was going out on my Chamberlain Liftmaster unit since it was older (1997). I have Fidelity Home Warranty (highly recommended) which referred/recommended me to Design Array Garage Door Store to fix my unit. Mike came out and did an EXCELLENT job. He was able to fix my unit by changing the logic board, program my remotes, and mount my keypad remote to the garage wall which he was so courteous to do. I highly highly recommend this company. They treated me very well and I'm glad Fidelity sent them out.
