With the stove disconnected from the power, take one wire off of that sensor on the exhaust motor and see what happens. I'd say it's likely that sensor is defective, telling the control that the stove is still hot.

Have you unplugged the stove for a good while, to reset the control? If so, I suspect that the triac or relay that controls that motor is shorted.

There are three different snap discs and a "thermistor" on that stove. Usually troubleshooting is done by bypassing the sensor. Many set up a wire with the appropriate connectors on the end to lessen the likelihood of a short. This will work for the snap discs. Once you rule out none of those are causing a problem, it leaves the thermistor. Not sure how to troubleshoot those.... Always unplug when working in the cabinet.
