Instant Pot Burn Notice Error
The Instant Pot burn notice is not a malfunction — it's the overheat protection sensor doing its job. The sensor is a thermistor embedded in the base of the inner pot that monitors surface temperature. When it detects the bottom of the inner pot exceeding approximately 300°F (150°C) without sufficient liquid coverage — typically from scorched sauce or insufficient water — it halts the cooking cycle and displays 'Burn' (or 'OvHt' on some models). Understanding why it triggers helps you prevent it systematically.

Common Symptoms
- 'Burn' or 'OvHt' displayed on the Instant Pot screen mid-cycle
- Cooking cycle stops before pressure is reached
- Smell of scorched food from inside the pot
- Burn notice appears consistently with the same recipe
- Bottom of the inner pot shows dark brown or black residue after burn notice
Most Likely Causes
- 1
Insufficient Thin Liquid
Pressure cooking needs a minimum of 1 cup (240ml) of thin liquid — water, broth, or thin sauce — to generate steam. Thick liquids like tomato paste, cream of mushroom soup, honey, or cheese sauce don't vaporize effectively. The bottom scorches before the unit pressurizes, triggering the burn sensor. Always place thin liquid at the bottom of the pot, with thick sauces layered on top without stirring.
- 2
Residue Left on Inner Pot Bottom
Using the sauté function before pressure cooking (for browning meat, sautéing aromatics) leaves fond (browned food residue) stuck to the inner pot bottom. This residue scorches before the rest of the liquid heats up. Deglaze the pot after sautéing — add liquid and scrape the bottom with a wooden spoon until all browned bits are dissolved before switching to pressure cook mode.
- 3
Starchy Liquids Without Dilution
Rice, pasta, legumes, and potatoes release starch into the liquid, making it thicker and more prone to settling and scorching. These ingredients need adequate water ratios: at least 1:1 liquid to starch volume for grains, and at least 1 cup additional liquid for beans. Adding a teaspoon of oil also reduces foam and starch precipitation on the pot bottom.
- 4
Dirty or Discolored Inner Pot Bottom Sensor Area
Over time, hard water mineral deposits and cooked-on residue on the outer surface of the inner pot (not the interior — the exterior bottom that sits on the heating plate) can insulate the temperature sensor, causing erratic temperature readings. Cleaning the exterior bottom of the inner pot with white vinegar removes mineral scale.

Quick DIY Checks
Never force the Instant Pot lid open after a burn notice — the pot is still pressurized. Cancel the cycle, allow the float valve to drop on its own or use the steam release handle with steam-rated gloves, then open the lid.
Hot liquid inside the inner pot can scald on contact. Use silicone mitts when handling the inner pot immediately after a burn notice event.
- 1When burn notice appears: cancel the cook cycle, wait for pressure to release naturally or use quick release, then carefully open the lid. Do not force the lid open under pressure.
- 2Inspect the inner pot bottom: use a wooden spoon to scrape along the bottom of the pot. If you feel resistance or see dark stuck-on bits, deglaze — add 1/2 cup warm water and scrape all browned residue free. This is the most common fix and takes 2 minutes.
- 3Assess your liquid: pour or measure the remaining liquid. If under 1 cup, add thin liquid (water or broth) to bring total to at least 1.5 cups. If the original recipe called for thick sauce, layer it on top of thin liquid without stirring — don't mix thick sauce into the liquid at the bottom.

- 5Adjust your recipe technique: if burn notice is a recurring problem with a specific recipe, the fix is usually (1) deglaze after sauté, (2) add thin liquid first, then layer thick ingredients, (3) add a splash of oil to reduce starch foam, (4) do not stir after layering — let the liquid work up from the bottom.

Repair vs Replace
Burn notice is almost never a hardware failure — it's a cooking technique issue 95% of the time. No parts needed. If the inner pot bottom is warped or severely pitted from repeated burn events, a replacement inner pot costs $25–$35 and is a worthwhile fix. The heating plate and sensor only need replacement if the unit won't heat at all.
Est. Repair Cost
$0 (technique adjustment) to $15 (new inner pot if bottom is warped)
Est. Replacement Cost
$80–$200 for a new Instant Pot

Frequently Asked Questions
- Why does my Instant Pot give a burn notice on rice?
- Rice releases amylose starch into the cooking water, causing the liquid to thicken at the bottom before pressure builds. Add a teaspoon of oil to the water — this breaks the starch gel and reduces scorching. Also use the rice-to-water ratio appropriate for your model (typically 1:1 for white rice in the 6qt). Do not use the sauté function before cooking rice — start cold in pressure cook mode.
- Does burn notice mean my Instant Pot is broken?
- No — the burn notice is the overtemperature sensor working as designed. The sensor detects that the inner pot base has exceeded safe cooking temperature without sufficient liquid to absorb the heat. If you consistently get burn notices with sufficient liquid and a clean pot bottom, test by running a plain water test: add 2 cups of water, pressure cook for 1 minute. If it pressurizes without a burn notice, the unit is fine — the issue is recipe-specific.
- Can I prevent the burn notice when cooking tomato-based sauces?
- Yes. Tomato sauce is high in sugar and acid, which scorches easily. The solution: layer the tomato sauce on top — never at the bottom. Put broth or water on the bottom (at least 1 cup), add your other ingredients, then pour the tomato sauce on top without stirring. The steam coming up from the bottom cooks the tomato sauce without it contacting the hot base. This technique works for any thick sauce.
