Hello TheWriteOne,
I am seeing lots of TCs for repair at present. I have NOT been receiving the forum posts automatically and was just having a look, as 'everything seems to have gone quiet', which implies Apple have a fix at last.
I have no idea why forum posts have stopped being sent to me by email... just one of those things?
Using Apple's help service as a newbie would, you would NEVER know that heat related failures were the top two enquiries by an order of magnitude (possibly two orders). At the peak of TC failures the two top threads had more than 100000 enquiries together. Occasionally these would be chopped back to a few thousand (there are comments on the forum of this happening) and now we have them completely invisible and buried in all the noise. I could not find this thread from the start. I had to go back to my old emails and link back to the thread that way.
What are you doing Apple? Why has historic prominence of TC failures been suppressed?
In answer to your question however... sorry I got sidetracked there... there is a heat-related flaw in the TC design. It was there from day one and made thousands of TCs worldwide drop like flies after about 18 months. It is fixable. The internal PSU (power supply unit) has no cooling, despite an internal fan being fitted, and stews in its own heat until it can take no more.
The PSU was blamed as being a 'bad batch' and Apple issued the serial number range for swap-out, as these numbers occupied the majority of the failures. Statistically that may look correct but there is more to it than that.
The poor design persisted. Some slightly beefed up parts were installed that could maybe withstand a life of higher than designed temperatures, and this seemed to delay the failures.
However, time has passed (no pun intended) and some of the beefier TCs are now beginning to die. Apple will not touch them as they are outside the serial number range they allotted, so I (and probably others) have been seeing them. Design-wise nothing has changed...
I will now appear to shout but the capitals are merely for emphasis...
APPLE FIT AN INTERNAL FAN TO THE TC - THERE ARE 3 ERRORS CONNECTED WITH THIS:
1. THE FAN HAS NO AIR-INLET HOLE.
2. THE FAN DOES NOT BLOW THROUGH THE PSU, IT IS POINTING ONTO THE SIDE OF THE HARD DRIVE.
3. THE FAN, IN NORMAL OPERATION, IS NOT EVEN TURNED ON.
Correct these design flaws and the failure rate will drop like a stone. This is what I do. Others opt for an external PSU, which has many additional benefits.
