FRIGIDAIRE FGEF3032MW - Manual

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.

Electonic Oven Control Fault Code Descriptions
Fault Code
Runaway Temperature. Oven heats when no cook cycle is programmed. Likely Failure/Cause
Suggested Corrective Action
Shorted keypad or Selector Switch.
F11
1. Reset power supply to range - Disconnect power, wait 30 seconds and reapply power. 2. Check/reseat ribbon harness connections. 3. Replace the EOC.
EOC Internal software error or failure.
F12 F13
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
EOC Internal hardware error of failure.
F15
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
EOC Internal software error of failure.
F16,F17 F18
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
Open oven sensor probe circuit. Shorted oven sensor probe circuit.
F30
(F30) Check resistance at room temperature & compare to RTD Sensor resistance chart. If resistance is correct replace the EOC. If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring harness between EOC & Sensor Probe connector. (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. If resistance is correct replace the EOC.
F31
Electronic Oven Control (EOC) over temperature. Higher than normal temperature detected on the EOC circuit board.
F60
1. Verify proper assembly of backguard panel. Check for damaged or loose panels, brackets, endcaps, etc. 2. Check for blocked ventilation slots in control panel rear cover. 3. Inspect oven vent for proper assembly and air flow. 4. Verify operation of cooling fan (if present).
F90 F91 F92 F93 F94 F95
If lock motor runs: 1. Test continuity of wiring between EOC and lock switch on lock motor assy. Repair if needed. 2. Advance motor until cam depresses the plunger on lock motor switch. Test continuity of switch contacts.
If switch is open replace lock motor assy.
3. If motor runs and switch contacts and wiring harness test good, replace the EOC. If lock motor does not run: 1. Test continuity of lock motor windings. Replace lock motor assembly if windings are open. 2. Test lock motor operation by using a test cord to apply voltage. If motor does not operate replace lock motor assy. 3. If motor runs with test cord check continuity of wire harness to lock motor terminals. If harness is good replace the EOC.
Door lock motor or latch circuit failure.
• 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.

If Oven is cold: 1. If fault code is present with cold oven test oven temperature sensor probe circuit resistance. Use RTD scale found in the tech sheet. 2. Replace probe or repair wiring connections if defective. 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 RTD 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.

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, Cancel
or
Clear/
Off
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,
Cancel
or
Clear/Off
.
Note:
Changing calibration affects normal Bake mode. The adjustments made
will not change the Self-Cleaning cycle temperature.
