Control Feature Procedure Results

H1 Oven temperature

adjustment

Press BAKE pad.

Enter 550 on the digit pad.

Immediately press and hold BAKE pad for 3

to 5 seconds.

Oven can be adjusted from -35 to +35

degrees in 5-degree increments by pressing

AUTOSET pads. To avoid over adjusting the

oven, move temperature 5 degrees each

time. Wait 4 seconds for the data entry timer

to expire to accept the change. Temperature

adjustment will be retained even through a

power failure.

Increasing or decreasing oven

temperature does not affect self-

cleaning temperature.

H1 Temperature display Press and hold CANCEL and BAKE pads

for 3 to 5 seconds.

Allows user to change

temperature display between

°F or °C.

H1 Clock display Press and hold CANCEL and CLOCK pads

for 3 to 5 seconds.

Allows user to turn clock display

on or off.

H1 24-hour clock Press and hold CANCEL and FAVORITE

pads for 3 to 5 seconds.

Allows user to toggle clock

display between 12-hour or

24-hour format.

H1 Factory default Press and hold CANCEL and KEEP WARM

pads for 3 to 5 seconds.

Allows user to reset clock to

factory settings.

H1 12-hour shutoff Control cancels cooking operations and

disables relay drives 12 hours after last pad

touch.

See Sabbath mode to disable.

H1 Sabbath mode Hold CLOCK pad for 3 to 5 seconds to

activate Sabbath mode.

Hold CLOCK pad for 3 to 5 seconds to

disable Sabbath mode.

Desired bake function must be initiated

before entering Sabbath mode.

"SAb" flashes for 5 seconds,

then remains on until timed-out

or canceled. (Status SAb is not

fault code 5A6.) All pad inputs

are disabled except CANCEL

and CLOCK. 12-hour shutoff is

disabled, allowing bake mode

operation for 72 hours. The oven

light is not disabled.

H1 Child lockout Press and hold CANCEL and COOK &

HOLD pads for 3 to 5 seconds. "OFF"

displays in temperature display area.

"LOCK" flashes while door is locking.

To reactivate control, press and hold

CANCEL and COOK & HOLD pads for 3 to

5 seconds.

This safety feature prevents

children from accidentally

programming the oven. The

electronic oven control is

disabled.

Child lockout features must be

reset after a power failure.

H1 Diagnostic code display Press and hold AUTOSET pad when

applying power to the range.

Cycle through the codes using the number

pads 1 through 5.

The last 5 diagnostic codes will

be stored in the non-volatile

memory.

See "Description of Error

Codes" for explanation.

"Quick Test" Mode for H1 Electronic Range Control (ERC)

Follow procedure below to use the quick test mode. Entries must be made within 32 seconds of each other or the

control will exit the quick test mode.

1. Press and hold CANCEL and BROIL pads for 3 to 5 seconds.

2. Once the control has entered the "Quick Test" mode, release both pads.

3. Press each of the following pads indicated in the table below.

NOTE: Press the pad once to activate the response.

Press the pad a second time to deactivate the response.

NOTE: This mode must be entered within the first 5 minutes after power up.

NOTE: If the temperature sensor is greater than 400° F or if the temperature sensor reaches 400° F while under

test, the Quick Test mode will be disabled.

Error diagnostic codes can only be viewed by entering the Diagnostic Code Display Mode.

Each error code is four digits long and is created based on the following table.

Digit Description

Primary System: 1 – Local to the control circuit board

3 – Sensor or meat probe

4 – Control input

9 – Door lock

Measurable: d – Diagnostic: measurable parameter

c – Control related, replace control

Secondary System: Sequential numbering

Oven Cavity: 1 – Upper oven (or single cavity oven)

2 – Lower oven

c – Control specific

Diagnostic Code Display Mode can be activated by pressing and holding the AUTOSET pad for 3 to 5 seconds at

power-up. Diagnostic Code Display Mode can only be started while powering up the control.
