Commission and Operation
3.1
General Operation
To select a program:
1. Touch the “ON” (“ON/OFF” on double ovens) control.
2. Select the desired function (example: BAKE)
3. Select the desired specific operation from the sub-menu (example:
CONVECTION BAKE)
4. Select the temperature (example: 425o)
3.2
Turning off the oven
To turn off the oven, touch the "OFF" (“ON/OFF” on double ovens)
control. The oven will turn off and the time of day will appear in the
display.
3.3

message is displayed as shown in 3-1.
11:23 PM
Power Failure
Figure 3-1: ”Power Failure” message displayed
This message is displayed to advise that the incoming power was
disrupted (power failure, etc.). It does not require any type of technical
service.
The ”Power Failure” message can be cleared by performing the following:
1. Turn the oven on by touching the ON/OFF (“ON/OFF” on double
ovens) control.
2. Turn the oven off by touching the ON/OFF (“ON/OFF” on double

Technical Information

3.4.1
Special Features
Self Clean Function (P / Self Clean Models Only)
When the Self Clean function is selected, the oven is heated to very high
temperatures to burn off any residue inside the oven cavity.
The duration of the Self Clean function is not a timed function and is
based on the amount of soiling inside the oven cavity. Total time will vary
depending on the condition of the oven interior.
Once the Self Clean Program completes and the oven cools, wipe the
interior clean with a damp cloth to remove any remaining residue.
3.4.2
Door Lock (P / Self Clean Models Only)
The door lock is operated via a motorized control. During the Self Clean
function the door automatically locks after one (1) minute. The door
remains locked until the Self Clean process has completed and the oven
temperature has dropped below 392° F (200° C).
If the Self Clean function is accidentally started, shut off the oven and wait
for the oven temperature to drop and for the door lock to release. This
may take several minutes.
The door lock can be activated while in the Service Mode. See section 6,
Fault Diagnosis.
3.4.3
Master Chef (all Models except H394)
The “Master Chef” menu feature is designed to ease operation and
improve cooking results. This feature uses a list of selectable preset
functions for commonly cooked foods. Users can select the type of food
from a menu and simply reply to a few basic inputs (i.e. weight, etc.) The
oven performs the necessary functions automatically to ensure a perfectly
cooked meal.
20
Master Chef Ovens
Technical Information
3.4.4
Child Safety Lock (All Models)
The child safety lock is used to prevent children from operating the oven
or to conserve standby power when the oven will not be used for an
extended period of time.
To activate the child safety lock:
1. Slide the lock to position “O”.
2. The oven cannot be operated & the clock will not be displayed.
To deactivate the child safety lock:
1. Slide the lock to position “I”.
2. The oven can then be operated & the clock will be displayed.
Warning
Using the Child Safety Switch does NOT disconnect all sources of power
within the oven. To safely disconnect power during service shut off the
main supply via the circuit breaker.
Note
For further detailed appliance operation, refer to the Operating Manual for
that model.

Cooling Air Intake
The Cooling Fan (Figure 4-1, Item 9) takes in the air through the opening
below the Door. The air flows between the Outer and Interior Glass
Panes and into the area between the Housing and Upper Holding Plate
Insulation Mat.

Vapor Intake
The Cooling Fan takes in the vapor through the Vapor Outlet (Figure 4-1,
Item 8) and the Exhaust Duct (Figure 4-1, Item 10).
4.4
Cooling Air Path
The Cooling Fan moves the air and vapor into the air vents (Figure 4-1,
Item 7) and through the opening between the Bottom Plate and the Lower

Cavity Temperature Sensor (1R30 & 4R30)
The Oven Cavity Temperature Sensor is located in the guide tube of the
Upper Heating Elements (Figure 4-2, Item 1). The Sensor sends a signal
back to the Main Electronic. The oven cavity temperature is calculated
and displayed via the Display Electronic.

Roast Probe (2R30 & 5R30) (All Models Except H394)
The Roast Probe can be used to monitor the core temperature of meat
and poultry. The long pointed end of the probe is inserted into the thickest
portion of the meat. The short end of the probe is inserted into the roast
probe socket located on the right side of the oven cavity. For optimum
cooking results ensure the probe does not contact any bones within the
meat or poultry.

The Self Clean Temperature Sensor is located in the Vapor Outlet
(above the Catalyst) and monitors the oven temperature during the Self
Clean Mode. Refer to Figure 4-4.

Thermal Cut-Outs (1F1 & 3F1)
Each separate oven cavity is equipped with a High Temperature Thermal
Cut-Out. The cut out is designed to interrupt the power in should the
temperature exceed 680oF (360oC) during operation modes.
4.12.1
Thermal Cut-Outs (2F1 & 4F1) (P / Self Clean Models
Only)
Each separate oven cavity is equipped with a High Temperature Thermal
Cut-Out designed to interrupt the power should the temperature exceeds
968oF (520oC) during the Self Clean mode.
4.13
Convection Fan (1M2/1 & 2M2/1)
The Convection Fan is mounted to the rear wall of the oven. It
pressurizes a large volume of air in the small cavity located in the rear
wall of the oven to produce true convection.
Figure 4-5: Convection Airflow

Rotisserie Motors (1M15 & 2M15)
Two 120 VAC Rotisserie Motor are mounted to the rear wall of the oven.
These motors provide drive for the Rotisserie Shafts.

Cleaning & Care Information
5.1.1
PerfectClean
PerfectClean® is a smooth, nonstick surface that cleans up easily with a
sponge. The following items are coated with the exclusive Miele
"PerfectClean®" finish:
Oven Walls
Roasting Pans
Anti-Splash Tray
Oven Runners
Do not clean PerfectClean items in a dishwasher. Some detergents
contain compounds that could damage the finish.
To properly clean the surfaces, use a sponge and a solution of hot water
and liquid dish soap for cleaning. Do not use abrasive cleaners, ceramic
cleaners, metal scourers, or oven cleaners.
After cleaning, rinse thoroughly with water. The water should run off the
surface easily. Any residue will hinder this effect. Stubborn baked on
grease may need to be soaked first to loosen deposits.
Clean up all spills as soon as possible to prevent stains. Spilled fruit
juices can permanently discolor surfaces; however the discoloration does
not hinder the efficiency of the finish.
5.1.2
Manually Cleaning the Oven Cavity
Danger
Allow the oven to cool before cleaning.
To make cleaning easier
Remove the oven door
Remove the runners
Lower the upper heating element
Clean the oven surfaces with a solution of hot water and liquid dish
soap and a sponge.
Do not use abrasive cleaning agents, hard brushes, metal scouring
pads, steel wool, knives or other abrasive materials.
Do not use oven sprays on any part of this oven.
Dry surfaces before reassembly.
