No it doesn't actually bypass it, it is in series with the one on the freezer.
If the one on the freezer is bad it could be by-passed and then the external thermostat could be used to control the temp, but first you need to know definitively what the problem is and then you need someone who fully understands what they are doing to accomplish this.
Good luck, here's hopping you have some really cold beer soon!
