Frigidaire FEFL79DCF Service Data Sheet

P8 P5

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.

Likely Failure Condition/Cause

Suggested Corrective Action

Fault Code

1. (F10 only) Check RTD Sensor Probe & 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.

2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply power.

3. (F11, 12 & 13) If fault returns upon power-up, replace EOC.

1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance chart.
If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring
harness between EOC & Sensor Probe connector.

2. (F30 or F31) Check resistance at room temperature, if less than 500 ohms, replace RTD Sensor
Probe. Check for shorted Sensor Probe harness between EOC & Probe connector.

1. (F40) Check the wiring.

2. (F40) Replace the Cooktop Lockout Control Board.

3. (F40) Replace EOC.

1. (F90, 91, 92, 93 & 94) Check the wiring between EOC & Lock Motor Micro Switch.

2. (F90, 91, 92, 93 & 94) Replace the Motor Door Latch assembly if necessary.

3. (F90, 91, 92, 93 & 94) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam.

4. (F90, 91, 92, 93 & 94) Check to see if Lock Motor Coil is open. If open, repl;ace Lock Motor
Assembly.

5. (F90, 91, 92, 93 & 94) Lock Motor continuosly runs - if Micro Switch is open, replace Lock Motor
Assembly.

6. (F92, 93 & 94) Check oven door Light Switch - if open, replace Switch.

7. If all situations above do not solve probem, replace EOC.

REPLACE CONTENTS IN BAG

To Remove Warmer Drawer:

1.

Turn power off before removing the warmer drawer.

2. Open the drawer to the fully opened position.

3. On the right glide you will find a shield attached with a hex-head screw (see figure 1). Using a 1/4” socket
and ratchet remove the shield.

4. Locate glide lever on each side of drawer, pull up on the left glide lever and push down on the right glide
lever.

5. Pull the drawer away from the range.

To Replace Warmer Drawer:

1. Replace shield on the right glide of the drawer body.

2. Pull the bearing glides to the front of the chassis glide (see figure 2).

3. Align the glide on each side of the drawer with the glide slots on the range.

4. Push the drawer into the range until levers “click” (approximately 2”). Pull the drawer open again to seat
bearing glides into position. If you do not hear the levers “click” or the bearing glides do not feel seated
remove the drawer and repeat steps 2-4. This will minimize possible damage to the bearing glides.

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 STOP/CLEAR to end bake mode.

TEMPERATURE ADJUSTMENT

1. Set EOC to bake at 550°F.

2. Within 5 seconds of setting 550°F, press and hold the bake pad for approximately
15 seconds until a single beep is heard (longer may cause F11 shorted keypad
alarm).

3. Calibration offset should appear in the display.

4. Use the slew keys to adjust the oven temperature up or down 35°F in 5°F
increments.

5. Once the desired (-35° to 35°) offset has been applied, press STOP/CLEAR.

Note: Changing calibration affects normal Bake mode. The adjustments made will not
change the Self-Cleaning cycle temperature.
