#93642 - I have my doubts
Responding to: ???'s previous message
When temperatures close to freezing ocurr the unit doesn't work

I have my doubts this is a component, more likely it is a bad contact (solder or through-plating).

Many moons ago, I spent a week in Paris, France supervising a group that resoldered intermittent boards and soldered wires in every plated hole. I got a pile of resoldered boards and started testing them in the machine and as they proved good the boards pulled were sent to the resoldering group. Eventually the equipment did not react to the environment.
