SAFE SERVICING PRACTICES

To avoid the possibility of personal injury and/or property damage, it is

important that safe servicing practices be observed. The following are

examples, but without limitation, of such practices.

1. Before servicing or moving an appliance remove power cord from

electrical outlet, trip circuit breaker to OFF, or remove fuse.

2. Never interfere with the proper installation of any safety device.

3. GROUNDING: The standard color coding for safety ground wires is

GREEN

GREEN WITH YELLOW STRIPES

. Ground leads are not

to be used as current carrying conductors. It is extremely important

that the service technician reestablish all safety grounds prior

to completion of service. Failure to do so will create a potential

safety hazard.

4. Prior to returning the product to service, ensure that:

• All electric connections are correct and secure.

• All electrical leads are properly dressed and secured away from sharp

edges, high-temperature components, and moving parts.

• All uninsulated electrical terminals, connectors, heaters, etc. are

adequately spaced away from all metal parts and panels.

• All safety grounds (both internal and external) are correctly and

securely reassembled.

Oven Calibration

Set the electronic oven control for normal baking at 350°F. Obtain an average

oven temperature after a minimum of 5 cycles. Press CANCEL or CLEAR

to end bake mode.

Oven Temperature Adjustment

(some models - do not use Bake or Broil while adjusting the oven

temperature):

1. Press & hold the BAKE key pad and release after the display begins flashing

the factory temperature setting of 00.

Note: If the oven temperature has been previously adjusted from the factory

setting, the current temperature adjusted value will flash in the display instead.

2. You may increase the oven temperature in 5°F increments with each press of

the UP ARROW key pad to a maximum oven adjustment of +35°F. You may also

adjust the oven temperature downward in 5°F increments with each press of

the DOWN ARROW key pad ( total adjustment range of -35 to +35 F. Note: Your

oven control was factory set in the (Fahrenheit) °F Temperature Display Mode.

To change for (Celsius) °C, see Changing the Temperature Display Mode

in the Oven Control Functions section of this Use & Care Manual.

3. If no other key pad is pressed after 5 seconds the display will begin to flash.

4. If you do not want to keep the display adjustment, press the CANCEL or

CLEAR key pad before the oven control beeps. This will cancel the temperature

adjustment procedure. To start this procedure over again begin with step 1

above OR;

5. If you want to keep the adjustment, wait until the display quits flashing and the

oven control beeps once.

6. The oven temperature adjustment has be accepted by the oven control and the

display will return to the time of day.

Notes: The oven temperature adjustment may be made if your oven control has

been set to operate in the (Celsius) °C Temperature Display Mode. In this

case each press of the UP ARROW or DOWN ARROW key pad will adjust in 1°C

increments upward (maximum +18°C) or downward (maximum -18°C), depending

on which arrow key pad is pressed.

Electronic Oven Control (E.O.C.) Fault Code Descriptions (some models-models that display F1 or F3)

Note: Only two fault codes are displayed by this control - F1 or F3. Generally, F1 display implies the electronic oven control itself has detected an internal

malfunction. F3 implies the control has detected a sensor probe failure. In either case, an alarm will accompany a displayed F1 or F3.

1. Shorted keypad.

2. Control's internal checksum may have become corrupted.

3. Control has sensed a potential runaway oven condition. Control

may have shorted relay, RTD sensor probe may have gone bad.

1. Open RTD sensor probe. Note: The EOC will initially display an F1

for this condition. The EOC thinks a runaway oven condition exists.

2. Shorted RTD sensor probe. Note: The F3 for shorted probe should

only occur when the oven is active or when an attempt is made to

enter a mode.

Likely Failure Condition/Cause

Suggested Corrective Action

Fault Code

1. Disconnect power, wait 30 seconds and reapply power. If fault returns

upon power-up, replace EOC.

2. Check RTD sensor probe and replace if necessary. If oven is

overheating, disconnect power. If oven continues to overheat when

the power is reapplied, replace EOC. Severe overheating may require

the entire oven to be replaced, should damage be extensive.

3. Replace EOC.

1. Check resistance at room temperature and compare to RTD sensor

resistance chart. If resistance does not match the chart, replace RTD

sensor probe.

2. Check resistance at room temperature, if less than 500 ohms, replace

RTD sensor probe.

This document describes the Electric Ranges with ES 100/105 Electronic Oven Control, providing essential information for servicing, operation, and troubleshooting. It emphasizes safe servicing practices and offers detailed guidance on oven calibration, temperature adjustment, and fault code interpretation.

Function Description

The Electronic Oven Control (EOC) is the central component managing the oven's functions, including temperature regulation, baking, broiling, and displaying operational status. It interacts with various sensors and heating elements to maintain desired cooking conditions. The control is designed to provide precise temperature management for optimal cooking results. It also incorporates safety features, such as fault code detection, to alert users and technicians to potential issues, preventing runaway temperatures or other malfunctions. The EOC can operate in both Fahrenheit and Celsius temperature display modes, offering flexibility based on user preference.

Usage Features

Oven Calibration:

To ensure accurate temperature control, the oven should be calibrated. This involves setting the electronic oven control to a normal baking temperature of 350°F and obtaining an average oven temperature after a minimum of five cycles. The CANCEL or CLEAR button is used to end the bake mode after calibration.

Oven Temperature Adjustment:

The EOC allows for fine-tuning of the oven temperature to compensate for variations or personal preferences. To adjust the temperature, press and hold the BAKE key pad until the display begins flashing the factory temperature setting of "00." If the temperature has been previously adjusted, the current adjusted value will flash instead.

Increasing Temperature: Press the UP ARROW key pad to increase the oven temperature in 5°F increments, up to a maximum adjustment of +35°F.
Decreasing Temperature: Press the DOWN ARROW key pad to decrease the oven temperature in 5°F increments, down to a maximum adjustment of -35°F.
Temperature Display Mode: The control is factory-set to Fahrenheit (°F). To change to Celsius (°C), refer to the "Changing the Temperature Display Mode" section in the Use & Care Manual.
Saving or Cancelling Adjustments: If no key pad is pressed for 5 seconds, the display will flash. To cancel the adjustment, press CANCEL or CLEAR before the control beeps. To save the adjustment, wait until the display stops flashing and the control beeps once. The display will then return to the time of day.
Celsius Mode Adjustment: If the oven control is set to Celsius, each press of the UP ARROW or DOWN ARROW key pad will adjust the temperature in 1°C increments, with a maximum range of ±18°C.

Maintenance Features

Safe Servicing Practices:

Prioritizing safety during servicing is crucial to prevent personal injury or property damage. Key practices include:

Power Disconnection: Always remove the power cord, trip the circuit breaker to OFF, or remove the fuse before servicing or moving the appliance.
Safety Devices: Never interfere with the proper installation or function of any safety device.
Grounding: Ensure all safety ground wires (typically GREEN or GREEN WITH YELLOW STRIPES) are correctly reestablished before completing service. Ground leads must not be used as current-carrying conductors. Failure to reestablish grounds creates a potential safety hazard.
Electrical Connections: Verify that all electrical connections are correct and secure.
Wire Dressing: Ensure all electrical leads are properly dressed and secured away from sharp edges, high-temperature components, and moving parts.
Terminal Spacing: All uninsulated electrical terminals, connectors, and heaters must be adequately spaced away from all metal parts and panels.
Reassembly: All safety grounds (internal and external) must be correctly and securely reassembled.

Fault Code Descriptions (F1 or F3):

The EOC displays fault codes to indicate specific malfunctions. Only F1 and F3 codes are typically displayed.

F1 Fault Code: Generally indicates an internal malfunction within the electronic oven control itself.
- Likely Causes: Shorted keypad, corrupted control's internal checksum, or the control sensing a potential runaway oven condition (which could be due to a shorted relay or bad RTD sensor probe).
- Corrective Actions: Disconnect power, wait 30 seconds, and reapply. If the fault persists, replace the EOC. Check and replace the RTD sensor probe if necessary. If the oven is overheating, disconnect power; if it continues to overheat upon power reapplication, replace the EOC. Severe overheating may necessitate replacing the entire oven.
F3 Fault Code: Indicates a sensor probe failure.
- Likely Causes: Open RTD sensor probe (initially displays F1 as the EOC thinks a runaway condition exists) or shorted RTD sensor probe (F3 for shorted probe occurs when the oven is active or an attempt is made to enter a mode).
- Corrective Actions: Check RTD sensor probe resistance at room temperature against the RTD scale. Replace the probe if the resistance does not match. If resistance is less than 500 ohms, replace the RTD sensor probe.

Fault Code Descriptions (F10, F11, F13, F30 or F31):

Some models may display additional fault codes.

F10 (Runaway Temperature):
- Corrective Actions: Check and replace the RTD Sensor Probe if necessary. If the oven is overheating, disconnect power. If it continues to overheat upon power reapplication, replace the EOC. Severe overheating may necessitate replacing the entire oven.
F11 (Shorted Keypad) & F13 (Bad Micro Identification/EEPROM Identification/Checksum error):
- Corrective Actions: Disconnect power, wait 30 seconds, and reapply. If the fault returns upon power-up, replace the EOC.
F30 (Open probe connection) & F31 (Shorted Probe connection):
- Corrective Actions: Check RTD sensor probe resistance at room temperature against the RTD Sensor resistance chart. Replace the probe if the resistance does not match. Check the sensor wiring harness between the EOC and the sensor probe connector. For F31, if resistance is less than 500 ohms, replace the RTD Sensor Probe. Check for a shorted Sensor Probe harness between the EOC and the Probe connector.

Resistance Temperature Detector (RTD) Scale:

This scale provides a reference for checking the resistance of the temperature probe at various temperatures, aiding in diagnosing sensor probe failures. For example, at 32°F, the resistance should be 1000 ± 4.0 ohms, and at 350°F, it should be 1654 ± 10.8 ohms.

Circuit Analysis Matrix:

This matrix outlines the EOC relay states for different functions (Bake, Broil, Door Open, Door Closed), indicating which L1 to Bake, L1 to Broil, and Door Switch COM-NC relays are active. For instance, during Bake, both L1 to Bake and L1 to Broil relays are active (Broil alternates with the Bake element). When the door is open, the Door Switch COM-NC relay is active.
