JennAir Range Code 1d12: Temperature probe circuit alert

What 1d12 means

A 1d12 message on a JennAir range such as the JIS1450DS or JDS1750ML says the oven temperature sensor, the control, or the wiring in the sensor circuit may have a problem. In the oven you will usually see a stopped cycle and a code in place of the temperature. It belongs to the same 1d family as 1d11, 1d21 and 1d22.

Common causes of 1d12

Oven temperature sensor problem
Control board not reading the sensor properly
Wiring problem in the sensor circuit

✓ One safe check you can try

1. Open the oven door and let the cavity cool down. 2. Press Cancel and close the door. 3. Cut power at the breaker for sixty seconds, then restore it. 4. Run a brief Bake test. 5. If 1d12 shows again, call us and do not continue baking.

! Why to stop there

Sensor and wiring are inside a hot cavity and behind panels.
Control and sensor problems need a meter to tell apart.
Using the oven without a proper reading risks overheating food and cookware.

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.

1d121d12 questions

Does 1d12 mean the same as 1d11?

They share the same meaning: the oven temperature sensor, the control or the wiring. On site we use extra tests to find out which of the three actually failed.

The oven heated, then stopped. Why?

The control keeps checking the sensor while the oven runs. If the reading disappears or jumps, it stops heating and shows the code, even partway through a recipe.

What does a 1d12 visit include?

We inspect the sensor, its wiring and the control, explain what we found, and give you a written price. Approved repairs come with a 30-day workmanship warranty.
