Fujitsu-General AOH12LSAC Manual

[jaimea]

Can anyone provide me with a service manual for the AOH12LSAC ?? Thanks...

What is your problem?

After some 30 seconds to a minute, the timer light flashes on the indoor unit. Another tech told me the problem was with the PWB in the outdoor unit. I switched PWBs between 2 identical outdoor units and the problem switched as well indicating that there is indeed a fault on the board.

I forgot to add that the system does not cool or heat.

If only timer light flashes than you have communication problem between indoor and outdoor unit.
Since you swapped PCB-s and problem is related to that PCB than you should change that PCB.

Changing the PCB is not an option because the local distributor wants some 300+ euros. With the schematic, there should be no problem in finding the faulty component(s). Hence the need for the manual.

We are all hostages of the Big Corporations in the face of the "local deelers" and alike them. I evaluate your chances of having repaired a PCB at 1 from 100. Good luck.

In that regard, I'm pretty fortunate. With some 40+ years as an electronics technician and with some pretty fancy test equipment and tools at my disposal, there hasn't been a board yet that I haven't been able to fix and we're talking about consumer, industrial, and avionics equipments. It's just a question of how much time one wants to spend (or has to spend).

Jaimea, which PCB are you talking about?
Controller PCB, main board on top,
TR PCB on left hand side
Or ACTPM, Diode Bridge underneath the controller PCB?
Check your PM's

Just tried to send you a PM but they are disabled??
