Food is consistently undercooked or overcooked compared to recipe times.

Safety first: Use a food thermometer to verify safe internal temperatures when adjusting recipes.

• 1. Verify sealing: Ensure the sealing ring, float valve, and steam release valve are in good condition so the cooker can reach full pressure.
• 2. Perform water test: Run a 10-minute pressure cycle with 2 cups of water. Note how long it takes to reach pressure and whether steam leaks. Abnormal behavior suggests a hardware issue.
• 3. Adjust recipes: If hardware checks out, adjust cook times in small increments (±2–5 minutes) to match your specific Chefman model’s behavior.
• 4. Replace sensors (advanced): If the unit clearly runs too hot or too cool, consider replacing the bottom NTC sensor and/or pressure sensor module.
