An oven that will not reach temperature, heats slowly, or does not heat at all is a frequent call across Larchmont. The cause depends on whether the oven is gas or electric, and on the igniter, the element, the sensor, or the control.
Notes by Brand
The same symptom can have different causes depending on the brand. Here is how we approach oven not heating across the roster.
Wolf
A gas oven slow to heat often has a weakening igniter that glows but cannot fully open the valve. Electric and dual-fuel models point to the bake element or a relay.
Viking
We test the bake element or gas igniter and the temperature sensor. A drifting sensor drives slow or uneven heating.
Thermador
Pro ovens point to the igniter or element and the relay board. We test each circuit and read any E-code.
Monogram
A GE-platform F2 over-temperature or an F3/F4 sensor code guides the diagnosis. We test the sensor and relay.
Kitchenaid
An F2-E0 over-temperature or an F3-E1 sensor code points the way. We test the element, sensor, and relay.
Jenn-Air
F#-E# codes name the fault. We test the bake element, the RTD sensor, and the control relay.
La Cornue
The vaulted oven relies on burner performance and the thermostat. We check the igniter, burner, and thermostat calibration.

Indications and What We Check
| Symptom | Likely Cause | What We Check |
|---|---|---|
| No heat | A failed element or igniter | Test the bake element or the gas igniter |
| Slow to heat | A weak igniter or a drifting sensor | Test the igniter current and the sensor |
| Over-temperature code | A sensor or relay fault | Measure the sensor and test the relay |
