    The old gooseguide say's to replace exhuast fan M13, or remove paper blocking fan M13.......... nothing else listed. could be a problem with the IOB or BCU depending which pcb drives the fan.................

      Could be a problem with the wiring harness. Bad/dirty/loose connector or open lead.

      From the Point-to-Point, four leads from CN679 (connector at the fan) to CN215 pins A1,A2,A3, &A4 on BCU. Pins A1&2 appear to be motor power. A4 shows as motor speed signal from the BCU. Pin A3 shows as a signal from the motor to the BCU and therefore is the lock signal. A loose connection to A3 could cause vibration to result in the SC.

        did you ck the old fan for "free spin"
        in a pinch i pull the bearing label.a little triflow oil,a can of air on the impellers and
        do this till it spins like a top.a little lithium grease, cover it up wth some packing tape
        to keep it sealed and have seen a 75% success ratio..are you sure on the fan you changed?
