How To Fix A Not Whistling Pressure Cooker
If the Pressure Cooker is not whistling then one should not shake it but check 2 things: Whether there is no leakage of steam from any where else especially where the rubber gasket is there or from the safety valve because in such a case the steam is escaping and food will not get cooked.
A weight is placed on a pressure cooker and every time the pressure rises above the threshold pressure in the sealed chamber, the weight creates a whistle sound. People use this whistle as an indication that their food has been cooked.
