In experienced hands, a
judicious touch of freeze spray can be just perfect for quickly isolating overly temperature sensitive defective components, and this persons particular case would be a good candidate.
A little reading up on component specs before use is good.
A little perusing of a schematic before use is good too. You could be violently altering bias points in a circuit designed to be at an overall temperature that is more stable. A case in point would be the output section biasing circuitry in a power amp. So what does happen to a component and the surrounding circuit when the temperature drops precipitously on that one part and the circuit is active? What kind of reaction should you expect? You should know before using the stuff. Most of the signal level and digital processing equipment is pretty safe to use freeze spray in though.
I would rather take care of a solder joint that would crack (I've never had one do this) now, than to have the joint fail later, which it would do so eventually if freeze spray is going to be messing with it.
