With no firm failure mechanism/mode information, Random Vibration followed by Thermal Cycling with few Power On/Off cycles is a good default condition. Screening should not stress the equipment such that fatigue failures are precipitated

Temperature cycling is an important test for electric heaters. The expansion and contraction from heating and cooling leads to one of the primary failure mechanisms for heaters. The different materials in the heater have different coefficients of thermal expansion. So, turning the heater on and off and cycling between near ambient and the operating temperature or maximum achievable temperature helps reveal failure mechanisms and locations. It can also be used as a stress in ALT of heaters. It is also important for temperature sensors in environments with significant temperature deltas.
