I've had a 4250 code on a PURY P250 YGM A, I ordered a new IPM board to replace it but Mitsu only sent the IGBTs ( the grey box where you apply thermic paste or putty) the PCB is actually called G/A Board and is literally clipped into the IPM ( not welded) Careful when you order spare parts.

Hi Bon, what was the issue. The second video you have not uploaded after this video. May I Know what the issue was and how you solved it? Now I am facing the same issue. After changing the inverter PCB the same issue persists.

If you have a cassette unit that needs to be programmed, you can add it or you have to start from scratch to start programming?

What mean program?

Hi! we encounter the same issue error 4250 on master accu, we replaced the blinking inverter board with a functioning one, but the units are still not working.

Voltage ok?

@@BonMj Yes, we have verified the voltage and power supply condition, and everything appears to be normal.
