Whirlpool WFE515S0JS Oven F1 E1 Error: Main PCB... | appliancefaults.com

Technical Background:

The F1 E1 error code on a Whirlpool WFE515S0JS oven indicates a communication failure or internal fault within the main control board (PCB). The MCU (Microcontroller Unit) on the board is likely detecting a fault during its self-test routine or is experiencing an interruption in its normal operating voltage (typically 5V DC and 12V DC). These voltages originate from the power supply section of the PCB.

Symptoms:

The homeowner reports that the oven displays an F1 E1 error code. The oven may not heat, the display may be unresponsive, or the buttons may not function.

Possible Causes:

Main Control Board (PCB) failure
Loose or damaged wiring harness connecting to the main control board
Power supply issues to the main control board
Internal short circuit within the oven components affecting the control board
Software glitch within the main control board's firmware

Solution:

1

Disconnect power to the oven at the breaker panel.
2

Locate the main control board (PCB) behind the control panel. Typically accessed by removing the back panel or top panel. Refer to the service manual for exact location.
3

Carefully disconnect all wiring harnesses from the main control board. Note the position of each connector for correct reassembly. Take pictures if necessary.
4

Using a 1/4-inch nut driver, remove the screws securing the main control board.
5

Install the new main control board, ensuring all connections are secure.
6

Reconnect all wiring harnesses, double-checking the positions.
7

Restore power at the breaker panel and test the oven functionality. Verify error code is cleared. If the error persists, further diagnosis is required.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed. The oven contains high voltage components that can cause serious injury or death.

Prevention:

Protect the oven from power surges by using a surge protector. Avoid excessive use of the self-cleaning cycle, as it generates high heat that can stress the electronic components. Regular cleaning can also prevent food debris from causing shorts. Check the oven vent is not blocked.

Expert Tip:

After replacing the main control board, perform a calibration procedure if available in the service manual. Some models require a calibration cycle after PCB replacement for optimal temperature accuracy. Consult the service manual for specific instructions on entering service mode (often achieved by pressing a specific sequence of buttons).

Frequently Asked Questions

•What voltage should I expect at the power input to the main control board?

You should expect to see 120V AC at the main power input to the control board. Use a multimeter to verify the voltage is present after disconnecting power.

•How can I test the continuity of the wiring harness to the main control board?

Disconnect power and then disconnect the harness from the board and the component it connects to. Use a multimeter set to continuity mode and test each wire in the harness individually. A good connection will show near zero ohms.

•Where can I find the service manual for the Whirlpool WFE515S0JS oven?

You can typically find the service manual online by searching for "Whirlpool WFE515S0JS service manual PDF". AppliancePartsPros.com or similar sites may have it available for download.
