Did you replace all three Hall Sensors with Honeywell SS41 Hall Sensors?
If you used different Hall Sensors, it is possible that they may operate differently to the original ones.
Hall Sensors can also be damaged if heat from the soldering iron is applied for too long.
Use a voltmeter to check the operation of all three Hall Sensors to confirm they are all working correctly.
Take a look at
this post and
this video for more details on testing the operation of the hall sensors.
