In one embodiment, an operating condition of a thermoelectric module is monitored. It is determined when the monitored operating condition exceeds a desired range. Upon determining the monitored operating condition exceeds the desired range, a thermal adjustment is applied to the thermal condition to direct the operating condition to within the desired range. The monitoring the operating condition may include measuring an operating temperature of an environment adjacent a surface of the thermoelectric module, a surface temperature of a portion of the thermoelectric module, a thermal differential between the first surface and the second surface of the thermoelectric module, and an output voltage of the thermoelectric module. The desired range includes a temperature range below a level at which the thermoelectric module will sustain thermal damage and a thermal differential capable of causing the thermoelectric module to generate a minimum desired output voltage.
