Good possibility? It is a definite FACT. With the 30 amp rating of the
conditioner,a 20 amp plug would be a requirement. Particularly on a 20
amp circuit.

Don't assume a 30A rating requires a 30A plug. That rating is the
maximum input current, and you can absolutely change the plug to a lower
rating if the load on the conditioner is less than full load. The
circuit protection is at the panel feeding the receptacle, so if that
receptacle is on a 15A or 20A circuit it is fine. If the load is too
high the breaker will trip.

Look at the pictures. Wouldn't you agree the breaker didn't trip?

We don't know what size breaker is on the circuit. We don't know what
the actual load amperage on the circuit is. It's entirely possible that
a bad connection caused overheating of the contact at well below even a
15A load.
