I have a Vollrath warmer #71001, the water temp is actually higher than the knob setting. Is there a way to calibrate the thermostat or do I need to replace it?

How do you know it’s running too hot? The label is only marked 1 to 10.
If you feel like it’s running too hot – no matter what setting it’s at, then the thermostat is probably bad. Therefore,
I recommend you have the thermostat replaced. Additionally, you should have the regulating thermostat replaced as well.
I’m not there to observe or test it with my test equipment, but it’s very likely that the operating thermostat isn’t controlling AT ALL (just ON or OFF), so the regulating thermostat (essentially a high-limit) is getting a workout.
FWIW: That operating thermostat is an EGO thermostat. The cost for a replacement is minimal when compared to any efforts necessary to calibrate it. It is NOT user-serviceable and, although there IS a calibration procedure for those thermostats (which VERY FEW technicians know about), it requires considerable TIME, special tools and be removed in order to calibrate it.

Never mind about what I typed. I just looked up the price for that 71001 and it’s a ridiculously cheap unit by commercial equipment standards.
There are many RESIDENTIAL countertop appliances that cost more than that thing…for which there’s NO parts/service support for.
If you feel that it’s not performing properly and is out of warranty, just replace the whole thing. A service call and parts necessary to fix it would EASILY exceed the cost of a new one.

Why do you think it is to hot? Did you measure the water temp with a calibrated thermometer? Is it boiling?
You can test control to function with this warmer by adding cold water and turning on. Turn temp knob all the way up till the water is above 140 F. Now watch the heat light and turn it down slowly till it goes out. If it does not go out the thermostat is welded on and needs to be replaced. And as Ectofix say’s the high limit is working overtime.
