In this paper, we analyzed the fire risk caused by the influence of the plastic film capacitor degradation on the single-phase motor. Plastic film capacitors are used to start single-phase motor of most commonly used electric fans in everyday life. We analyzed the effects of plastic film capacitors on the motor using some electric fans. The combustion test of the plastic film capacitor material and the calorific value of the motor according to the capacitance change were analyzed. When the capacitor terminal was opened and shorted due to capacitor degradation, the temperature of the motor was tested. As a result, those were confirmed that the motor was stalled and the temperature of the motor was higher than normal operation in both cases. We proved that the capacitor failure could lead to the higher motor temperature and it might ignite the electric products.
