Hey everyone, welcome to this channel! Today we'll be talking about the F8 or E7 error in Mabe or Haier air conditioners. Specifically, we'll be discussing when the error persists even after repairing the power supply problem on the condenser unit's circuit board. In most cases, the fault is caused by bad electrolytic capacitors in the power supply area, which is made up of an integrated circuit 1200P100, or rather, an NCP1200. If you're interested, this first problem was solved in a previous video; I'll leave the link below if you want to watch it. But in this case, the F8 or E7 error persisted even though the board no longer had power supply problems. So, the cause of the error was another component. You won't believe how many hours I spent trying to find the problem. In my case, the error persisted because the condenser fan motor, which is a BLDC type, has trouble starting. It can't do it on its own, and when the board sees that it's not turning, it blocks the air conditioner and displays the infamous error. F8 or E7.
