Methods and systems for calibrating a temperature control system in a vapor deposition chamber. A temperature sensor senses temperature within a semiconductor processing chamber and generates an output signal. A temperature control system controls a chamber temperature by controlling a heating apparatus based on the output signal. A method includes instructing the control system to target a setpoint temperature, and depositing a layer of material onto a surface in the chamber by a vapor deposition process. A variation of a property of the layer is measured while depositing the layer, the property known to vary cyclically as a thickness of the layer increases. The measured property is allowed to vary cyclically for one or more cycles. If there is a difference between a time period of one or more of the cycles and an expected time period associated with the setpoint temperature, the temperature control system is adjusted based on the difference.
