Learn Turkish: Kablo sıkışırsa, cihazda muhtemelen temassızlık başlıyordur. - If the cable jams, a loose connection is probably starting in the device.

The -dur suffix here does not state a hard fact. When added to a verb that already has a tense marker like -ıyor, it expresses an assumption, guess, or strong probability. So başlıyordur means 'is probably starting' or 'must be starting.' The word muhtemelen (probably) is often paired with this suffix to emphasize the guess.

Why use the aorist conditional sıkışırsa instead of the present conditional sıkışıyorsa?

The aorist conditional (sıkışır + -sa) is used for general rules, possibilities, or future hypothetical situations ('if it ever jams'). If we used sıkışıyorsa, it would specifically mean 'if it is jamming right now.' Since we are talking about a general cause and effect regarding the device, the aorist conditional is the natural choice.

How does the word temassızlık literally break down to mean a loose connection?

It starts with the root temas (contact or touch). Adding the negative suffix -sız (without) gives temassız (contactless). Finally, the noun-forming suffix -lık creates temassızlık, which literally translates to 'lack of contact.' In electronics and wiring, this is the standard Turkish term for a loose or faulty connection.
