Could a failing Silicone Sealing Ring cause the INSTANT POT DUO to have symptom: General Troubleshooting?

The sealing ring is the primary mechanical barrier for pressure retention; over time, the silicone loses its durometer/elasticity or develops micro-fissures. When the seal fails, the cooker cannot reach the necessary 10.2-11.6 psi to stabilize internal temperatures, leading to liquid depletion and localized overheating of the stainless steel base. Replacing the ring restores the hermetic seal and prevents the thermal runaway condition that triggers the burn message.

// ENGINEER'S LOG

The failure mode is categorized as a thermodynamic imbalance. The base NTC sensor is spring-loaded to ensure contact with the inner pot; if the pot bottom is warped or the element is contaminated with carbonized food debris, heat transfer becomes inefficient, leading to localized 'hot spots.' However, the 'loop' symptom most frequently points to steam bypass. As steam escapes, the latent heat of vaporization is lost to the atmosphere rather than contributing to internal pressure, resulting in the desiccation of the food load and subsequent scorching of the vessel floor. The controller interprets this rapid rise in resistance from the thermistor as a potential fire hazard and terminates the heating cycle.
