When the Oven Lies About Its Temperature
If your oven runs hot or cold, the cause is usually calibration, the temperature sensor, a weak element or igniter, or a leaking door seal. That's most of our oven temperature calls across metro Atlanta. You set 350 and the cake burns at the edges while the middle stays wet, or a roast takes 30 extra minutes. Here's how to narrow it down before you call us.

What "running hot or cold" actually means
Ovens don't hold one steady temperature. They cycle. Heat climbs past your setpoint, shuts off, drifts down, then fires again. A normal swing is roughly 25 degrees either way, which is fine for most cooking. Drift is different. Drift means the average is wrong, so everything browns too fast or nothing browns at all. Some ovens preheat correctly and then lose control halfway through a long bake. Note which pattern you have. Write down what you set, what the display says, and how the food came out. That detail narrows the cause more than anything else you can tell us.
Cause one: calibration and habits
Start with the cheapest possibility. Many ovens have a user calibration setting buried in the control menu, and it can get shifted by accident or set by a previous owner. Check your manual for the offset option. Then look at how you bake. A dark metal pan browns faster than glass. Racks crowded with two sheets block airflow, and opening the door to peek dumps heat fast. In a humid Atlanta kitchen the recovery takes longer than you'd think. Also confirm you aren't leaving convection on for a recipe written for standard bake. Fix these and some "broken" ovens turn out fine.
Cause two: the temperature sensor
Most electric ovens use a thin metal probe that sticks into the upper cavity. The control board reads its resistance and decides when to heat. When that sensor ages or gets coated in baked-on grease, the reading drifts. Symptoms that point to a sensor: the oven is consistently off by 40 or 50 degrees, or it overshoots badly then undershoots. Sometimes the probe gets bent against a rack and touches the wall, which reads hot. With the oven cool, look at it and see if it's obviously bent or crusted. Don't tug on it. Replacing one is a straightforward job for us.
Cause three: heating elements, igniters, and door seals
On an electric oven, a bake element that's partly failed still glows but puts out less heat, so the oven never quite gets there. Browning only from the broiler is another clue. On a gas oven, a weak igniter opens the valve slowly and burner cycles get long and uneven. That one is ours to handle, not yours. Then there's the door. Run your hand near the closed door while the oven is hot and feel for escaping heat. Look at the rubber or braided gasket for gaps, tears, or flattened spots. Check the hinges too, because a door that doesn't sit square leaks constantly and the oven runs cold trying to keep up.
Safe checks versus what we do
Safe for you: put a standalone oven thermometer on the center rack, run a 350 bake for 30 minutes, and read it. Repeat at 425. Clean grease off the cavity walls. Inspect the gasket and hinges, and confirm the calibration setting. Stop there. We take it further with a probe meter that logs the full heat cycle, so we see overshoot and recovery instead of one snapshot. We measure sensor resistance against spec at temperature, check element draw, and watch relay behavior on the control board. Anything behind a panel, near the gas line, or inside the control housing is our work. Call us with your thermometer numbers ready.
When the Oven Lies About Its Temperature — fast answers
How far off is too far off?
A swing of about 25 degrees around your setpoint is normal cycling. If a standalone thermometer shows the average is 35 degrees or more off your setting, or the oven never reaches temperature, something needs attention.
Can I just set the oven higher to compensate?
It works for simple roasting. It doesn't work for baking, because the drift often isn't the same at every temperature. You'll guess wrong at 425 after calibrating your habits at 350. Better to fix the cause.
Does self-cleaning damage the sensor or control?
The cycle runs very hot and stresses sensors, gaskets, and door latches. It doesn't usually cause failure by itself, but it can push a marginal part over the edge. Plenty of temperature calls come in right after a self-clean.
How it works
- Step 1
Tell us the symptom
Call us or fill out the form. Describe what the machine is doing: the noise, the smell, the error code. Brand and rough age help us load the right parts.
- Step 2
We schedule a window
Metro Atlanta traffic is real, so we book arrival windows that hold up. You get a heads-up before the technician rolls out, and we work around your day where routes allow.
- Step 3
Diagnose, then repair
The technician tests the unit, finds the failed part, and explains what's wrong in plain words. You approve the work before anything gets replaced. Most common parts ride on the van.

Why homeowners call us
- Built for Southern humidityDamp air punishes appliances. Dryers take longer, gaskets grow mildew, ice makers sweat and freeze up. We see these patterns weekly, so we check for them instead of chasing the obvious part first.
- Pollen-season know-howSpring coats every condenser coil in yellow film. A fridge that struggles in April often just can't shed heat. We clean it, test airflow, and tell you what actually failed versus what was choked.
