Record whether it lands high, lands low, or wanders. Then work round the door with a banknote shut in it, checking the grip is the same at every point. ### Mass hides the problem A light domestic oven tells you immediately when something is wrong — it overshoots, recovers badly, and cakes fail. A heavy commercial-style cavity smooths all of that out. It holds heat so well that a sensor drifting by fifteen or twenty degrees produces food that is nearly right for months, and by the time somebody is sure, the drift is considerable. That is why we measure rather than adjust to taste. ### The door is a heat source in reverse Nobody thinks of a door as part of the temperature system, but a heavy one under spring tension is holding a seal against a frame, and when it stops doing that evenly the cavity develops a cold corner. Owners describe it as an element problem because that is what it feels like. Checking the seal takes two minutes and regularly saves an element. The temperature sensor has drifted The reading is wrong and the control acts on it faithfully. It happens slowly, shows nothing, and accounts for more of these calls than everything else together. The door has stopped sealing Once a gasket goes hard, or a hinge slackens, heat escapes from one region only. The cavity never finds equilibrium and one side runs cooler than the other. The heat source is weak rather than dead An element or an ignitor that is failing gradually will heat, slowly and never quite enough. It is the answer less often than people assume, which is why it is checked third. What does a thermometer say after thirty minutes? On a cavity this heavy, anything shorter is a reading taken while it is still heating. Thirty minutes gives a number worth acting on. Is one part of the oven worse than another? Variation from place to place accuses the door or the circulation fan. Wrong everywhere by the same amount accuses the probe or the board. Did it follow a self-clean cycle? The hottest hours of the oven's year. Things that were marginal frequently do not survive it, and a seal or a sensor is the usual casualty. Runs hot, runs cold, or drifts during a bake What it usually means Probe before element: the sequence is most of the answer One cold corner indicts the door, never the element If the oven shows a code, the digits after the letter are the message What to do in the next ten minutes Stand a separate thermometer mid-cavity, dial in 350, and leave it thirty minutes before you look — a quarter of an hour only tells you about the climb.

You can, and people do for years. It works for baking at one temperature and stops working the moment a recipe is temperature-sensitive or somebody else uses the oven. It also hides a drift that is usually still moving. Correcting it is not an expensive visit. ### Why does it need thirty minutes to test? Because you are measuring the cavity, not the air near the element. A heavy oven spends the first twenty minutes moving heat into its own metal, and a reading taken during that tells you about the climb rather than about where it settles. --- **[Read full article: Oven will not hold its temperature](https://dcsmiami.support/symptoms/range-oven-will-not-hold-temperature/)**
