Ans: Most of the modern appliances like fridge and AC come with a bigger voltage range for hassle-free operation. This means that if the earlier models of the fridge worked between 200-240 V range, the latest models offer a bigger range of 170-290 V. Thus, the refrigerators come with in-built low and high voltage cut-off but they don’t come with in-built voltage stabilizers. Using a voltage stabilizer might not be that important unless the voltage in your area shoots up or down beyond or below the limits constantly.
