Receptacle contacts wear out. A plug that falls out of its own weight is arcing every time something draws current through it. Replacements are a few dollars each and this is the most common genuinely worthwhile small electrical job in a house of this age – with the breaker off, confirmed dead with a tester.

This is most common in homes built roughly 1940 to 1980. Post-war and mid-century — copper supply, aging cast iron stacks, 60 to 100 amp panels, first-generation central air.

You can handle this one yourself. No call needed.
