Common causes include: faulty igniter or ignition module, failed heating element (electric ovens), thermostat or temperature probe failure, gas valve issues, or clogged burner ports. Start by checking error codes on the control panel if equipped. If the oven lights but doesn't reach temperature, the thermostat or temperature probe is often the culprit. A certified technician can diagnose the root cause quickly.

Signs of compressor problems: unit not reaching temperature despite running constantly, compressor making loud knocking or grinding sounds, compressor starting and stopping rapidly (short cycling), compressor not starting at all, or high pressure shutdowns. Compressor failure is typically the most expensive refrigeration repair. Early diagnosis can sometimes allow for less costly repairs — don't wait if you hear unusual compressor noises.

Signs your oven needs calibration: food is consistently undercooked or overcooked at standard settings, cooking times are significantly longer or shorter than expected, the displayed temperature doesn't match an independent thermometer reading. Oven calibration should be part of every service visit and can drift over time from component wear. A variance of more than 25°F warrants professional calibration.
