  4 flashes is a bad mode shifter coil. You have to replace the mode shifter. You can check coil with multimeter. Unplug 2-wire connector and check across plug wires (red and yellow). There's two different types out there, some made with copper wire, others with aluminum. Copper coil reads about 98 ohms, aluminum reads about 65 ohms.

if shifter coil is open you can cut rivets and short out internal  fuse which opens,just make sure to install external fuse with holder in the supply line,and re test resistance before hookup[65-98 ohms]

  The problem with that is the internal fuse is a thermal type fuse. It opens based on temperature of an overheated coil, not the amount of current through the coil. The coil gets hot due to a higher coil current if the user opens the lid during the fill portion of the cycle. The coil gets 135vdc applied to it to pull the solenoid in but only needs 35vdc to hold it in. In early models, if the lid was opened at the wrong time, the 135vdc was applied for too long a period of time causing the coil to overheat. Adding an external fuse won't protect the coil if this happens because the fuse rating must be high enough to compensate for inrush current when voltage is first applied. You can however, replace the internal thermal fuse with one of the same rating. There are a couple different ones being used.

  The fuse is in the coil assembly of the mode shifter, not the motor/inverter. The mode shifter is the part that drives the agitator and basket. Check the coil to make sure it is faulty. If so, you must remove the inner tub, take out the whole outer tub and support to flip it over and replace the mode shifter.

Here's another thread about this with part numbers for the thermal fuses. I've got one sitting on my shelf, haven't decided if I'm going to rebuild it or not.
