Jck for Model Number fphn2899lf1 Fridge displaying SY EF. Ordered fan from your store. Replaced and made sure connections secure. Opened breaker for 20 min to clear error. Same error code after a while. Ran diagnostics. Was able to operate all other equipment (lights on/off etc), but using test 15 for the fan = no movement at all for high/low. I then accessed the main board and checked the voltages at the Brown/White and Red/White and got 12 V. Then Brown/White to Blue/White and got about 3 V (per other answers you provided). Next step is to replace main board, right? Thanks.
