Frigidaire 316905023 Service Data Sheet

SERVICE DATA SHEET -
Gas Range with ES 1000 Electronic Oven Control
NOTICE - This service data sheet is intended for use by persons having electrical
and mechanical training and a level of knowledge of these subjects generally
considered acceptable in the appliance repair trade. The manufacturer cannot be
responsible, nor assume any liability for injury or damage of any kind arising from
the use of this data sheet.
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 or
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 keypad to end bake mode.
Temperature Adjustment
1. While in a non-cooking mode, press and hold the bake key pad for 6 seconds.
2. The current calibration offset (temperature adjustment) should appear in the
temperature display.
3. Use the number key pads (0-9) to enter the desired amount of adjustment (up to
35°F).
4. Press the self-clean key pad to change the sign of the adjustment to a (-) if
necessary. A positive adjustment will not display a sign.
5. Once the desired adjustment (-35° to 35° F) has been entered, press the start
key pad to accept the change or the cancel key pad to reject the change.
NOTE: Changing calibration affects all Baking modes. The adjustments made will not
change the self-cleaning temperature.

3. If temperature sensor probe circuit is good but fault code remains when oven is cold replace the EOC.
If Oven is overheating:
1. If oven is severely overheating/heating when no cook cycle is programmed test oven temperature sensor probe circuit resistance using
the RED scale found in the service tech sheet. Also verify that the temperature sensor probe in properly installed in the oven cavity.
2. Disconnect power from the range, wait 30 seconds and reapply power. If oven continues to heat when the power is reapplied, replace
the EOC. NOTE: Severe overheating may require the entire oven to be replaced should damage be extensive.
