Apple's sixth-generation smartwatch, with optional cellular connectivity, released September 18, 2020. Model A2376, 44 mm.

Apple watch series 6 LTE sensor assembly ONLY replacement.

Hi guys,

The blood sensors on my Apple watch series 6 LTE suddenly decided to die.

No visible lights come from the sensors, none of the measurements work.

I did several shutdowns, force-restarts, hard-resets, let battery die and recharge, nothing changed.

The rest of the watch function is not effected.

I am perfectly able to do the repair the common way (open the whole watch and replace the entire back with the sensors), but i would prefer not to, as the repair is always messy, and always leaves the watch "scared" inside.

Can the sensor assembly alone be unglued from the back of an Apple watch with some heat and some isopropyl alcohol?

A picture from the net as an example:

After that it's just connecting a single connector and gluing it back.

Not sure there really is a way without going in from the top. I’d would review Step 8 from here Apple Watch Series 6 Teardown the iFixit teardown team believes it’s not that easy without breaking it.

Thanks Dan,

My goal is to replace it, hoping the problem is limited on the sensor group and not further inside the watch.

So breaking it is not important (as long as the rest of the back crystal stays intact).

If it doesn't work, then I'll just go in from the top.

I was hoping for info on how this can be unglued "safely" (ironic since i read about cases where the sensor group just "fell off")

@nikgeo - True in the older series Apple encountered issues, since Series 5 they appear to have solved the issue more effectively. I’m not sure which side will break, my money is on the glass piece.
