Maytag Oven F1E5 Error: Oven control memory fault
What Does Maytag Wall Oven Error Code F1E5 Mean? Error code F1E5 on a Maytag wall oven signals a non-volatile memory (EEPROM) failure on the main control board. The EEPROM is a small chip that permanently stores operating firmware, temperature calibration offsets, and cook presets. When the board’s startup routine detects that the EEPROM cannot […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A control board with a failed EEPROM cannot reliably store or retrieve temperature calibration data or safety parameters. Do not use the oven until the fault is resolved.
Can I reset the code?
Yes. A breaker reset may temporarily clear F1E5 if the EEPROM corruption was caused by a transient event. If physical EEPROM degradation is the cause, the fault returns every power cycle and the board must be replaced.
When to stop immediately?
Stop if you notice: F1E5 returns on every power-up regardless of reset duration, Calibration values cannot be saved after any reset attempt.
Symptoms You May Notice
Temperature calibration offsets reset after every power cycle
Any temperature adjustment set via the user calibration menu reverts to zero after the oven is turned off, confirming the EEPROM cannot retain written data.
Oven refuses to begin a cook cycle and immediately faults
The control board detects the memory failure during its startup self-test and locks out all heating functions before a cycle can begin.
F1E5 appears at power-up with no user input
The fault code displays within seconds of power being applied, indicating the EEPROM failure is detected during the board's initialization routine rather than during cooking.
Cook programs work during session
Temperature calibration adjustments work while the oven is on but are lost after power-off.
Possible Causes
Worn-out EEPROM chip on the main control board
The EEPROM undergoes thousands of read-write cycles over the oven's service life and eventually degrades to the point where it can no longer reliably retain data.
Requires ProfessionalPower surge corrupting EEPROM memory contents
A voltage spike wrote invalid data to the EEPROM sectors storing calibration values, causing the checksum validation to fail on every subsequent boot.
Requires ProfessionalControl board firmware update failure
An interrupted or failed service firmware update left the EEPROM in a partially written state that the board's startup routine cannot parse.
Requires ProfessionalSafe Checks You Can Do
-
1
Perform a 5-minute breaker reset
Turn off the oven's dedicated circuit breaker and leave it off for five minutes to fully discharge the control board. Restore power and observe whether F1E5 clears on startup.
If the fault was caused by a transient power event rather than physical EEPROM wear, a clean-power reboot may allow the board to re-initialize memory successfully.

Attempt to set and save a temperature calibration value
After a successful reset, navigate to the Oven Temperature Calibration menu (typically accessed by pressing and holding Bake for several seconds on MEW/MMW models). Set an offset and power the oven off, then back on, to verify the value was retained.
If the value resets to zero after a power cycle, the EEPROM write function has failed and the control board requires replacement regardless of other symptoms.
When to Call a Professional
Contact a qualified technician if:
- Board replacement is the only remedy for a physically failed EEPROM chip
- Fault returns immediately after a new board is installed — wiring harness requires inspection
- Unit is within warranty period — a service call may be covered by Maytag
