Denys Mitchell Key Takeaways
- A failed fan element in convection mode is the most common cause of uneven heating on OCS series.
- Error code F1 points to an oven temperature sensor fault — a quick, affordable repair.
- Baking element failures cause hot spots at the bottom of the oven cavity.
- Calibration offset can be adjusted in the service menu without any parts replacement.
- Replacing a faulty temperature sensor on Asko ovens starts from $130.
The Bottom Line
Uneven heating in an Asko OCS or OEP oven usually traces back to a faulty temperature sensor (F1) or a failing fan element — both are repairable starting from $130 and well worth fixing given the longevity of Asko appliances.
Asko oven not heating — this comprehensive guide covers everything you need to know.
Asko OCS and OEP series ovens are designed for precise, even heat distribution, so burnt edges with an undercooked center — or vice versa — point to a specific component failure rather than a cooking technique issue. Identifying the cause quickly prevents wasted meals and unnecessary technician visits.
Quick Diagnosis Table
| Symptom | Error Code | Likely Cause | DIY Fix? |
|---|---|---|---|
| Uneven baking, burnt edges | F1 | Temperature sensor fault | No — sensor replacement |
| Convection mode not heating evenly | None | Failed fan element | No — element replacement |
| Bottom burns, top undercooks | None | Baking element failure | No — element replacement |
| Oven runs too hot or too cool | F2 | Thermostat or sensor drift | Sometimes — calibration first |
| Fan runs but no heat | F6 | Fan element open circuit | No — technician required |
Check the Temperature Sensor First
The temperature sensor on OCS and OEP models is a slender probe mounted on the back wall of the oven cavity. Error code F1 indicates the sensor is reading out of range. A technician can test resistance with a multimeter — a working Asko sensor reads approximately 1,080 ohms at room temperature. Sensor replacement starts from $130.
Inspect the Fan and Fan Element
In convection mode, the circular fan element behind the rear panel heats air before the fan distributes it. A partial failure — where only some coil sections are broken — produces hot and cold zones inside the cavity. If the fan spins freely but heat is uneven in convection mode, the fan element is the most likely culprit.
Try a Calibration Adjustment
If the oven consistently runs 10–20°C off without triggering an error code, access the calibration offset through the control panel's settings menu (hold the temperature button for five seconds on most OCS models). An offset of up to ±35°C can be dialed in without any parts replacement.
When to Call a Technician
Error codes F2 and F6 both require a technician to safely access the oven's rear panel. Fan element replacement involves working inside a high-voltage cavity — not a safe DIY task. Most Asko oven element repairs are completed in a single visit starting from $130.
Prevention Tips
Avoid lining the oven floor with foil — it disrupts air circulation and forces the heating elements to work harder. Run the self-clean cycle no more than twice a year, as the extreme temperatures accelerate sensor wear on OCS models.

Frequently Asked Questions About Asko Oven Not Heating
When your Asko oven not heating problem affects only the top or bottom element, the issue is almost always a burned-out heating element. Asko ovens use separate upper (broil) and lower (bake) elements. Test each element individually by setting the oven to broil mode versus bake mode.
If your Asko oven not heating issue is intermittent, the oven temperature sensor (thermistor) may be drifting out of calibration. On Asko OCS and OP series ovens, this sensor is located at the rear wall of the oven cavity. Its resistance should read approximately 1,100 ohms at room temperature.
The Asko oven not heating problem combined with error code E01 confirms a faulty temperature sensor. Replacement sensors are available from Asko parts distributors. The repair takes about 30 minutes and does not require removing the oven from the cabinet.
