No, as long as light finger pressure will retract it. There is a
compression spring in the cooler thermostat assembly to close the sensor
when it has cooled adequately. It is NOT fast. In operation, there is a
limited amount of travel to open the bypass valve. When testing the
sensor in boiling water, it extends way past that limit and can stick a
bit. It is not a failure. Just press it back by hand and install.
