1, pressure relief is actually a cooling process. When the ambient temperature is high, the cooling speed is slow and the pressure relief is slow. When the ambient temperature is low, the cooling speed is fast and the pressure relief is fast.
2. The electric pressure cooker has air leakage fault. Check the silicone sealing ring of the pressure limiting valve and the silicone sealing ring of the floating valve of the electric pressure cooker. If there is no problem, it is the pressure switch. Adjust the pressure switch. The electric pressure cooker leaks air and is easy to burn out at high temperature. It is recommended to stop using it immediately for maintenance.
