These are commercial grade openers. I paid somewhere around $650 each. In a visit with my supplier he offered to take them back and get me two more. Mutually we agreed we can't agree that the problem would be fixed....
This is a pic of mine, it is a commercial grade also that lifts a 12x24 ft insulated steel door that is 3" thick. Notice the little box on the perforated angle iron mounting bracket? It is slightly above the opener unit and has 4 wires connected to it.
That is what changes the frequency from the troublesome 3** the opener puts out, to the friendly 2** frequency which is compatible with my radio and 20 fixtures with 6 tube T-8 florescent lights and supposedly LED lights. It is a LiftMaster product sold and installed by my door company out of Ames Iowa.
