SAFETY PRECAUTIONS

This service information is intended to be used by a qualified service technician who is famil-
iar with proper and safe procedures to be followed when repairing any electrical appliance.
All tests and repairs should be performed by a qualified service technician who is equipped

with proper tools and measuring devices. All replacements should be made by a qualified
service technician using only Maytag Appliances Sales Company replacement parts.

Improper assembly or adjustment may occur if service or repair is attempted by persons
other than qualified service technicians or if parts other than Maytag Appliances Sales Com-

pany replacement parts are used. Improper assembly or adjustment can cause hazardous
conditions.

There can be risk of injury or electrical shock while performing services or repairs. Injury or
electric shock can be serious or even fatal.

SECTION 1. COMPONENT DESCRIPTION

COMPONENTS

Meat Probe: Senses the internal tempera-

ture of products during a baking function.
The meat probe is an NTC, or negative

temperature coefficient, which means the

resistance value decreases as the tempera-

ture increases. See meat probe chart below

for resistance values.

Type: Calibration:

NTC Thermistor 9938 ohms (150°F.)

122 18963 ohms
150 9938 ohms

156.2 8846 ohms

165.2 7456 ohms

210.1 3886 ohms

Membrane Switch: The means to make a
switch contact, thus instructing the elec-

tronic control system to perform a desired
function. The membrane switch is a simple
set of two contact surfaces containing

conductive material, one on the back layer
of MYLAR and the other on the front layer

of MYLAR. There is also a center section of

non-conductive MYLAR material that has a
hole punched out of it at each switch con-

tact position. The thickness of this spacer

MYLAR determines the push force required

to close the contacts between the front

contact strip and the rear contact strip.

Typically, the push force required to close a

contact is 12 to 18 ounces.

Electronic Control: A programmable soft-
ware component that controls oven, clock,

timer and various other functions. The

control maintains oven temperatures in
either bake, broil, or clean. It is adjustable to

maintain correct temperature offsets. It is
also programmed with self-monitoring

circuitry, which determines if a potential

unsafe condition is present, shuts the sys-
tem down and displays the appropriate fault

code. Fault codes are covered in product
specifications sections 3 and 4.

Touch Sensor Technology: With this new
technology a positive charge and negative

charge is present around each pad. This
creates an electrostatic field that emanates

around, below, and through the glass front.
When the consumer touches a key pad, this

disturbs the electrostatic field and draws
capacitance energy. This input is read by

the module, which in turn signals the con-
troller to respond, and the desired function
is performed. In order for a function to be

performed, a conductive material must
bridge the gap between the negative charge

present at each pad.

Display Board: Displays time-of-day clock,
oven temperatures, and any other function
programmed into the electronic control

system. The display board also acts as the
input means from the membrane switch

and sends those commands to the power
relay board to process, implement, and

monitor.

Power Relay Board: Contains the intelli-
gence in the electronic control system and
controls all oven functions, clock, timer, ,and

various other consumer programmable
inputs. The PRB has a relay mounted to it
for each function it provides.

Oven Sensor: A device to monitor internal

oven temperature. The sensor has a PTC or
positive temperature coefficient, or a resis-

tance value that increases with temperature.
Allows the electronic control to maintain a

temperature setting through means of

resistance matching with the control-se-
lected temperature. Example: The oven
control is set at 350°F, the oven sensor

resistance at room temperature is approxi-
mately 1060 ohms. As the oven heats, the

16009721 COMPONENT DESCRIPTION 1-1

_1999 Maytag Appliances Sales Company

resistance of the sensor increases. The
resistance of the sensor at 350°F is approxi-
mately 1654 ohms. The electronic control

monitors the resistance value of the sensor
and cycles the oven heating elements off.

As the temperature in the oven decreases,
the resistance of the sensor decreases. At a

predetermined temperature setting, the

electronic control will initiate another heat-
ing cycle in the oven elements. See oven

sensor chart at right for resistance values.

FAULT CODES

SECTION 3. TROUBLESHOOTING

Test Access The test mode can be accessed by holding the stop time key down at

power up or by holding the stop time key down for 10 seconds within 5
minutes of power up mode, No other key can be pressed before the

stop time key, that would block the test mode access.

Test Exit Exit the test mode by pushing the cancel key or test will self-terminate

after 16 seconds from the last key command chosen.

Test Function Test mode is perfomed by pushing a keypad and testing for an output

response. When the keypad is released, the output is terminated and

the display will return to the "-" display. The following is a list of key
actions and responses.

NOTE:

1. Each time a key is pressed a tone will sound.

2. If there is a red dot on the IC-chip and the display board when you touch the oven light key,

the oven light will come on and a beep will occur. The beep is to let you know that there is

a good circuit, in case the light is blown. Also, when you press the fan speed key on a dual
speed downdraft, it will beep each time you touch the key. The first beep will be the high

setting, the second beep will be the low setting, and the third beep will be off.

used to set the offset between positive and negative(-). Entered values

are rounded to the next 5° increment. (Example: pushing key 3 will
display a 5° increment).

The clock can be set to be displayed in 24 hour form. Also,
temperature can be displayed in degree "C". To access, hold either

timer keys down on power up. The two left digits will display the

format for the clock, the right digit will display "F" or "C." The display
can be toggled by pushing the bake or upper bake key to toggle the
clock. The temperature display can be toggled from F to C by pushing

the broil key or upper broil key on a double oven control.

Membrane Switch: The means to make a
switch contact, instructing the electronic
control system to perform a desired function.

The membrane switch is a simple set of two

contact surfaces containing conductive
material, one on the back layer of MYLAR

and the other on the front layer of MYLAR.
There is also a center section of non-conduc-

16009721 TROUBLESHOOTING 3-11

O1999 Maytag Appliances Sales Company

tive MYLAR material that has a hole
punched out of it at each switch contact
position. The thickness of the MYLAR

spacer determines the push force required
to close the contacts between the front

contact strip and the rear contact strip.

Typically, the push force required to close a

contact is 12 to 18 ounces.
