No, "the doorbell rang" is not an independent clause; it is an independent clause. An independent clause contains a subject and a predicate and expresses a complete thought. In this case, "the doorbell" is the subject, and "rang" is the predicate, making it a complete idea.
The independent clause is 'When the doorbell rang.' It is an adverbial clause, modifying the verb 'was sleeping'.
The independent clause in the sentence "Trevor was sleeping when the doorbell rang" is "Trevor was sleeping." This clause can stand alone as a complete thought, while the phrase "when the doorbell rang" serves as a dependent clause that provides additional context.
"You rang the doorbell" is an indepent clause, because it can exist on its own. So is "but no one answered," because it is using a coordinating conjunction, which acts as a independent marker for an independent sentence. See https://owl.english.purdue.edu/owl/resource/598/01/.
