DEcosse, glad to meet you, I knew there would be some experts on this forum...
But in this case, before diving deep, I'd give out a +1 to Bob R. A careful cleaning with either clean air, or better yet, PLASTIC SAFE spray contact cleaner, (Please note the plastic safe, it is on the front of the can, available at Lowes in a dark blue can) and take a careful look at how they are making contact. I'm a trained electrician who also spent 28 years in manufacturing keeping machinery running at the most horrendous times, and I've found over the years that a connector often can be saved.
Not that you should not replace it in time, but you might be surprised how little damage there is in there, or dirt, or critter stuff...
As usual, JMHO.
