You are correct. It is a 6299.
I am not real quick on the keyboard but here are the details:
The cm15a was plugged into an outlet in a second floor bedroom. It controlled everything I asked it to. About two weeks ago, anything plugged into any outlet in the family room became uncontrollable with the cm15a. When I moved up to the cm15a, I removed all the transceivers from the house because the cm15a was supposed to receive all the house codes.
As part of the trouble shooting procedure, I moved the cm15a into the family room. Not only did it cease to control anything, I had to get the old transceivers out of the drawer and plug them in just to the the palm pilots (HR12a) to work.
So it looks like my family room has become disconnected from the rest of the house as far as the cm15a is concerned.
I doubt that a wire broke loose in the fuse box and it can't be a blown fuse since I did not have enough fuses in the box to dedicate two fuses to the 6299 so it piggybacks on other fuses. I know that this is not the best practice and I am considering having an electrician come in and put in a new larger box this time with breakers. But the permit and inspection costs are unreal in this area.
So before I tear open the fuse box again, I thought I would ask if there was a way to test the 6299. I will probably just buy another and when it arrives, I will open the fuse box. But if there was a test, I would test before spending money.
Thanks
