This phrase can also be used as an an Interjection, when someone is disappointed about some lost opportunity or when something does not go “right”. In that situation, the speaker might use this phrase in order to “cheer up” the person who is upset about that lost or missed opportunity.
The phrase “When One Door Closes, Another Door Opens” is Idiomatic because it is almost never referring, literally, to actual “doors”. And if the person speaking actually WAS referring to “doors”, then he or she would be showing his or her lack of discernment about how “doors” actually work.
This phrase is a Prepositional-Phrase of Time because of the word “When”. The word “When” is not referring to a specific time, but is referring to ANY time that one is in a situation where-in an opportunity is lost or missed (the “Door Closes”), and another (usually better) opportunity presents itself (another “Door Opens”).
When One Door Closes…
…Another Door Opens.
This phrase is a Proverb AND an Aphorism because, well… Those two things are quite often the same. The only difference is that an Aphorism can be ridiculous, Cliche, and sometimes not even true – where-as a Proverb is used to convey a general Truth or tid-bit of Wisdom. And, as the Universe is filled with far more opportunities (“Doors”) than every single human on the planet, collectively, for all time – past, present, and future – could ever take advantage of, then this is a general Truth of what we are experiencing collectively and “currently” as “Reality”. There-fore… a Proverb
Referring to any phrase as a “Saying” – though being the most commonly used – is actually kind of a ridiculous lexical term. However, for people who do not study Grammar, and probably do not even know what “Lexis” is – this is the most common term for things such as these.
Despite what a lot of text-books show and imply – Interjections are more than just one or two-word exclamations, such as:
Now, all of those expressions ARE Interjections, because they are used to express emotion, and display one’s feeling and/or opinion about something.
. But… an interjection can also be any expression (word, phrase, sentence, etc.) that is used to express one’s thoughts, feelings, opinions, or simply offer commentary on a situation – where-in the person is not asking a question and is not expecting there to be any further commentary on what is being expressed.
. There-fore, the phrase “When One Door Closes, Another Door Opens”, can also be used as an interjection for the same reasons as were explained in the first paragraph above. However, it should also be noted that this is usually (but not always) done by people who are (as explained in the section about Aphorisms, above) trying to sound wise by make some commentary on a situation where-in – not only is it not necessary, but – it is probably not the right time to say such a thing. And therefore, to do-so would not be welcomed, nor would it be appreciated.
So unless, you absolutely know that the person you are thinking of telling this phrase to will be receptive to what you have to say (like if the person is actually coming to you for consolation), and that that person may need to be reminded of this very well-known fact (as we all sometimes do)… then please… do not use this, or any other phrase like it, as an Interjection.
Smart people will thank you for it…
