The warm outlet with a loose terminal

Use was stopped and an electrician confirmed abnormal connection heating.

Initial observation

The homeowner recorded the location, timing and a photograph before changing the surface.

Competing explanations

Several plausible causes were retained until a repeatable trigger separated them.

Decisive clue

The linked check produced a pattern that aligned with one cause and weakened the alternatives.

Resolution

The source was corrected before finish repair, affected material was allowed to stabilize and the original trigger was tested again.

Outcome

No recurrence was reported during the verification period. The timeline and evidence were retained as part of the house history.
