Maytag Oven Error Code F13: Troubleshooting and Reset... | appliancefaults.com

Technical Background:

error code F13 on a Maytag oven typically indicates a software logic error within the Main Control Unit (MCU). This error can be triggered by voltage fluctuations, corrupted data, or component failure on the control board. The MCU relies on stable voltage paths and correctly executed software routines to operate. The EEPROM stores critical operating parameters and software. Damage or corruption to these can cause error codes. The 5V DC power supply circuit for the microcontroller may be failing.

Symptoms:

The oven displays an F13 error code on the control panel. The oven may not heat up, or the display may be unresponsive. The error may appear intermittently or constantly.

Possible Causes:

Power surge affecting the MCU.
Corrupted software in the control board.
Loose wiring connections to the control board.
Failure of the EEPROM (Electrically Erasable Programmable Read-Only Memory) on the control board.
Intermittent voltage fluctuations from the power supply.
Excessive heat causing component malfunction.

Solution:

1

Disconnect power to the oven at the breaker panel. Lock Out Tag Out (LOTO) procedures should be followed.
2

Wait 5 minutes to allow the capacitors to discharge.
3

Remove the oven control panel using a 1/4-inch nut driver to access the main control board.
4

Inspect all wiring connections to the control board for looseness or corrosion. Tighten or clean as necessary.
5

Using a multimeter, check the voltage at the power input terminals of the control board. You should read approximately 120V AC. Also, check the 5V DC output of the power supply on the board.
6

Reconnect power to the oven and observe if the F13 error code reappears.
7

If the error persists, the main control board likely needs to be replaced.

Safety Warning:

Disconnect power to the oven at the breaker panel before performing any troubleshooting or repairs. High voltage is present within the oven, and failure to disconnect power can result in serious injury or death. Always follow Lock Out Tag Out (LOTO) procedures.

Prevention:

Install a surge protector on the outlet powering the oven to protect against power surges. Periodically check the wiring connections to the oven for tightness and signs of corrosion. Avoid operating the oven during electrical storms.

Expert Tip:

Some Maytag ovens have a service mode that allows you to clear error codes or perform diagnostic tests. Refer to the service manual or manufacturer's website for instructions on accessing the service mode for your specific model. A common sequence is press Cancel, Cancel, Start, Cancel to enter the service menu.

Frequently Asked Questions

•How do I access the service mode on my specific Maytag oven model?

Consult the service manual for your specific model number. It may involve a button sequence (e.g., Cancel-Cancel-Start-Cancel) or require a special tool.

•What is the part number for the replacement control board for my oven?

Locate the model number on the oven (usually inside the door frame) and search for the control board part number online at appliance parts retailers or the manufacturer's website using that model number.

•If the voltage is correct, what is the next step to diagnose the F13 error?

If the voltage is correct and the error persists, the EEPROM data might be corrupted, or the MCU itself may be failing. Replacement of the main control board is generally the only solution at this point. Reflashing the board would be the next step, but requires specialized equipment.
