Methods and systems for detecting membrane blockage in a gas detector are disclosed. In some embodiments, the gas detector comprises a membrane defining a sensing chamber of the detector, the sensing chamber comprising a relaxed state pressure. The method comprises applying one or more forces on one or more walls of the membrane, wherein applying the force causes a volume change inside the sensing chamber. The method further comprises measuring a pressure change inside the sensing chamber, the pressure change being caused by the volume change. The method further comprises determining a rate of return to the relaxed state inside the chamber and determining a condition of the membrane based on the determined rate of return to the relaxed state.
