Infrared Thermometer Trouble Shooting

[BassNoid]

Ok !

Using a can of Freeze to cool a part that's over heating to ID it as a bad part has been a common practice.

How about using a Infrared Thermometer to Trouble Shoot.

ID a part as to hot to be good ??

Tricky to focus. At least mine is, and the laser guide is above the sensor, so needs compensating for. But in principle, a useful tool.

Interesting idea, but since you don't want the precise temperature just what's hot or not how about a thermal imaging camera, they are just hundreds of $ not thousands nowadays, you can even strap them on your portable telephone:

You can identify overheating parts, but many parts fail at normal operating temperature. Freezing them not only shocks them mechanically, but also puts them back below normal operating temperature for a moment. Thermometer won't help there.

I used FLIR One for iOS to observe driver temperature during power test.
