Wolf M Series Code 5021: Upper oven too hot during self-clean

What 5021 means

On Wolf M Series wall ovens like the SO3050TM/S/T or DO3050PM/S/P, 5021 is an overtemperature alert for the upper cavity during a self-clean cycle. The lower cavity equivalent is 5022. The control has seen the cavity hotter than allowed while cleaning, so it ends the cycle and shows the number. The oven may stay locked while it cools, and it will not finish the cleaning.

Common causes of 5021

Upper cavity temperature sensor reading wrong
Heating element or relay staying on too long
Control board misreading the clean cycle
Heavy food residue or grease burning hotter than normal

✓ One safe check you can try

1. Leave the door alone and let the oven cool until the lock releases. 2. Wipe out loose spills and heavy grease once it is cool. 3. Remove racks and foil from the cavity. 4. Flip the oven's breaker off for a minute, then on. Do not start another clean cycle if 5021 returns, and call us instead.

! Why to stop there

An overtemperature event involves heating parts and sensors that must be tested by a trained technician.
Running more clean cycles can stress the oven and the control.
We test the sensor and heat control, then give you a written price before any repair.
Our work has a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

50215021 questions

Is 5021 the upper or lower oven?

Upper. Code 5022 is the same alert for the lower cavity. Both only apply while the oven is running a self-clean cycle. Note which cavity showed it before calling so we plan the visit correctly.

Why is my oven door still locked?

The lock stays engaged until the cavity cools to a safe temperature after the alert. Wait for it to cool and the door should release on its own.

Can I use the oven for baking?

Often it still bakes, but we suggest holding off until it is checked, because the same sensor or relay that caused the clean-cycle alert can affect normal heating.
