Hi we have 2 mitsubishi reversible aircon units. We had a leak in the roof and one of the indoor units went bang. I have opened up the unit and checked that power is getting to the unit and the mains lead has power. I have the technical manual and it says check the power across the terminal block on termnals 1 and 2. There is no power here so I think maybe the PCB is dead. As we have 2 units I could swap the PCB's but I can't get the PCB out. It is slid into a carrier. How do you get the board out? Anyone know the rough cost of a replacement PCB?
