Confirming the power supply quickly eliminates a common, yet overlooked, obstacle.

Evaluate the Heating Elements

Heating elements often fail silently. Remove the oven’s back panel or access cover and visually inspect the bake and broil elements for cracks or blistering. Use a multimeter set to continuity mode to test resistance; a broken element will read as open circuit. During my experience, I replaced a cracked bake element, which restored reliable heating and saved me the cost of more complex diagnostics. For detailed testing procedures, see Effective Oven Repair Tips & Diagnostics for 2025.

Assess the Temperature Sensor

The temperature sensor regulates oven heat by communicating with the control board. Remove the sensor and test for resistance; typical values at room temperature are around 1000 ohms. A faulty sensor will produce inconsistent results, causing under or overheating. I once replaced a malfunctioning sensor, which stabilized my oven’s temperature. Remember, a faulty sensor can mimic heating element issues, so testing here is critical.

Check the Control Board and Relays

If the heating elements and sensors test fine, the control board might be at fault. Visual cues include burnt spots or swollen relays on the circuit board. Using a multimeter, verify that relays are functioning correctly. Replacing a relay is often more affordable than a full control board replacement.
