Okay, this is wacky. People think I'm crazy but I'm convinced that there is a random source of radio interference that jams my car remote and now is jamming my light in my garage.
Here's the deal. After installing an aftermarket remote starter in my car, I noticed that at certain times - and only when the car is parked in my driveway - that the remote ignores my commands. I can't unlock the doors and I can't start the car. I have to use the factory remote (which operates at a different frequency) to get into the car and disable the antitheft system. I've been living with it because it's more or less random.
The plot thickens....
I installed a Liftmaster 3800 garage door opener over the weekend. The light unit plugs into any outlet and receives the on/off commands wirelessly from the motor unit. It worked fine for days but now had stopped working. It stopped working the same day the aftermarket keyless entry stopped working on my car. I suspect they operate at around the same frequency.
I don't know what causes this interference and it comes and goes. It will be good for weeks, then stuff doesn't work for a few days, and then it works again.
I don't know exactly what frequency these things operate at. A quick google search of Code alarm systems makes me think they operate at 433 Mhz. I guess maybe the light in the garage is the same. It's also the same frequency at which my wireless thermometers operate. I pulled the batteries out of all of them but still cannot get my car nor the light in the garage to work.
Anyone have any idea what other household devices operate in the 400 Mhz range? This is driving me nutz.
Don't call me crazy,
