Temperature Sensor; Setting Temperature Offsets - Thermador ME301J Series Service Manual

Service Manual for Thermador Masterpiece J-Series Built-in Wall Ovens
models have true European convection (both a convection fan and a
convection element) in the upper oven and thermal convection in the
lower oven. MED models have true convection in all cavities.
Depending on the cooking mode selected, the fan may be used, with
or without the ring element, to circulate heat evenly throughout the
cavity in various cooking modes.
The ring element (240V 2000W) and/or fan blade are easily accessed
on the rear wall of the oven cavity behind the convection baffle. The
convection fan motor is accessible only from the rear of the unit.
Refer to the Element Strip Diagram to test the element at the control
module, or:
1. Remove 2 T20 screws on either side of the element terminals.
2. Pull the element toward you so that terminal wires are inside
the oven cavity.
3. Disconnect the wires from the terminals.
4. Use an ohmmeter to check for resistance of ~29 ohms.
