Whether you own a newer model or a unit that is several years old, this guide walks you through the brand-specific causes, model-by-model diagnostic differences, and the repair costs you can expect. Kenmore appliances have unique engineering choices that make generic troubleshooting guides insufficient — this guide focuses on what actually goes wrong in Kenmore units specifically.</p> <h2>Quick Answer</h2> <p>The most common causes of oven temperature wrong in Kenmore ovens are: Temperature sensor drift; Calibration needed; Convection fan failure. Estimated repair cost: varies by model and condition.</p> <h2>Affected Kenmore Models</h2> <p>This issue is most commonly reported on the following Kenmore oven models:</p> <ul> <li><strong>790.xxx (Frigidaire — sensor 316490000)</strong></li> <li><strong>665.xxx (Whirlpool — sensor WPW10181986)</strong></li> </ul> <h2>What Are the Common Causes?</h2> <h3>1. Temperature sensor drift</h3> <p>reads approximately 1080 ohms at room temp; drift causes 20-50F offset</p> <p>Our field data from Kenmore repairs confirms temperature sensor drift drives most complaints of this nature that we diagnose.</p> <h3>2. Calibration needed</h3> <p>Kenmore allows +/- 35F adjustment via Settings</p> <h3>3. Convection fan failure</h3> <p>uneven heat distribution perceived as wrong temperature</p> <h2>Step-by-Step Troubleshooting</h2> <p>Before starting any troubleshooting on your Kenmore oven, disconnect power at the circuit breaker or unplug the unit. For gas appliances, turn off the gas supply valve as well.</p> <ol> <li><strong>Identify your exact model:</strong> Locate the model number on the serial plate (typically inside the door frame, on the rear panel, or under the lid).
