Component test · Range / OvenMost electronic ovens use a platinum RTD probe, which works the opposite way to an NTC: resistance rises with heat. Many common sensors read about 1,080 Ω at room temperature and climb roughly 2 Ω per °F.
Guide · Range / OvenFirst confirm it is really slow: many ovens take around 10-15 minutes to reach 350°F, longer with large cavities or convection preheat. On electric ovens a partly failed bake element or a dead broil element (used during preheat on many models) slows preheat. On gas ovens a weak igniter that glows but draws too little current opens the gas valve late or not fully.
Guide · Range / OvenMost no-heat calls on electric ovens come down to a burned-out bake or broil element, a failed oven temperature sensor, or loss of one 120 V leg of the 240 V supply. Test elements and sensor with power off before suspecting the control board.
