Fujitsu (ASU24CL) Flash code

[Kahu]

Mini-split. Tripped breaker. On reset the CU cranked up and when I went inside the IC was blowing but not cold. Lights weren't on.

If you turn it off/on you get a quick 4-red/OP flash and slow 3-green/Timer. That happens with most of the button presses (and test).

If you leave it be... either on or off... it will flash 2 green/Timer, pause 15 secs, and same.

When I went back outside to look the CU/fan was off. hmmm... flipped breaker for a couple minutes then back on. CU/Fan doesn't even twitch, although inside unit fan motor runs (and flash codes as above).

247vac supply voltage. Same inside. Outside it makes it across boards and converts to 300vdc.. no LED on the main board but if I remove either thermistor it will rapid flash, which will go out if I plug that back in.

??? Sparse paperwork at hand so not enough info to OHM thermistors or check specific volts at connectors.
