Abstract
In one form, the present disclosure is directed toward a method of controlling temperature of a heater including a resistive heating element. The method includes applying power to the resistive heating element at a variable ramp rate to decrease temperature of the heater to a desired temperature setpoint, where the variable ramp rate is set to a desired ramp rate. The method further includes monitoring the temperature of the heater to detect a runaway condition and adjusting the variable ramp rate from the desired ramp rate to a permitted ramp rate in response to the runaway condition being detected.
