In all cases of spells cast, the practitioner has an ethical responsibility to keep full and correct records of the spells they cast.
If a candle spell "goes wrong" during the casting, immediately stop the casting , extinguish the candle and ground any and all energies you have raised.
If a candle spell "goes wrong" after the spell has been cast, consult your records (Book of Shadows) and check the ingredients (colours, timing, moon phase and house, incense and all of the other variables). If the spell is doing damage, it is up to you to do a correct reversal/banishment/grounding of the energies.
In both cases, you should be willing to take responsibility for your actions and their consequences.
Should you need to recast the spell, recheck the ingredients, and be very careful of your timing.
If a candle has no oxygen, its flame goes out.
There is nothing wrong.

Candles are a common component of many spells and rituals. If the candle is a spell candle with a specific single use, you should allow the entire candle to burn out on its own. If you must leave the area, place it somewhere safe and fire proof. I have left candles to burn out in the bathtub (no water in it) when I had to leave. If the candle is a spell candle, made with the expectation of relighting it, for example a seven-day prosperity spell, the candle is snuffed out, (do not blow it out) at the end of the allotted time of that segment of the spell. If the candle is part of a ritual, for example: the elemental candles used when calling a dismissing the elements (quarters, directions) then the candle may be snuffed out when you dismiss the elemental. If the candle is part of a ritual and used to invoke the deities then it should not be put out at the end of the ritual, but allowed to burn out on its own. In the case of large multi-use candles sometimes used for this purpose, you may snuff out the candle when you are dismantling the Altar after the ritual.
it melts then forms back onto the candle, dries, then rebuilds the candle. It is the fuel of the candle and is consumed during the burning process.

It goes out
it goes down
in case your electricity goes out.
The word is "candle."
As the candle is burning, some of the wax melts and turns into a gas in the atmosphere.
