    Has anyone got a spare (possibly dead) FF91/92/93/P procond control module?

    I’ve got one where the M34510E8SP MCU seems to have lost control of its P1 I/O ports (pins 28-31), resulting in it being unable to switch the triacs that control the evaporator fan and heaters on.

    I’m hoping to source a replacement MCU but in case that doesn’t happen I was wondering if there are any (dead) modules I could transplant the MCU from.

    Failing that a trusty Arduino or RasPi might add the FF92 onto the IoT band-wagon 🙂

    Hi feefifofum,
    How did you get on with the M34510E8SP MCU?
    I have the same problem it started at the time the yellow thermistor had failed.
    The freezer temperature reaches a temperature of -22 degrees the evaporator fan fails to operate.
    On start of the F/F P1 is displayed for a second then shows the freezer temperature.
    On power up the fan can run for 20secs then shuts off maybe the MCU is doing a self check.

    Amrik..
