Roper Range Error Code F5: Relay Board Communication... | appliancefaults.com

Technical Background:

The F5 error code on a Roper range typically indicates a communication problem between the main control board (MCU) and the relay board. The MCU sends signals to the relay board to control various functions, such as heating elements. If this communication is disrupted, the F5 error appears. Voltage paths and logic circuits within the boards themselves are suspect.

Symptoms:

The Roper range displays an F5 error code and may not operate correctly. The oven or cooktop burners may not heat, or the control panel may be unresponsive.

Possible Causes:

Failed relay board
Loose wiring connections
Damaged wire harness
Control board malfunction
Voltage fluctuations

Solution:

1

Disconnect power to the range at the breaker panel.
2

Locate the relay board, usually behind the control panel. Use a 1/4-inch nut driver to remove access panels.
3

Inspect the wiring harness for any signs of damage, such as frayed wires or melted connectors.
4

Use a multimeter to check the voltage at the relay board input, should be around 120V AC. Also, verify proper ground using the continuity setting on your multimeter.
5

Check the communication wires (usually low voltage DC, around 5V DC) between the main control board and the relay board for continuity. A wiring diagram is recommended.
6

If wiring is good and voltage is present, replace the relay board. Part numbers are typically located on the board itself.
7

If the error persists after replacing the relay board, replace the main control board.

Safety Warning:

Disconnect power to the range at the breaker panel before performing any repairs. Lock-out/Tag-out (LOTO) procedures must be followed. High voltage is present within the range.

Prevention:

Regularly inspect the wiring and connections around the range for any signs of damage. Avoid overloading the electrical circuit. Ensure proper ventilation to prevent overheating.

Expert Tip:

Some Roper ranges have a service mode. Consult the service manual for your specific model. Entering service mode might provide more detailed error information.

Frequently Asked Questions

•How do I access the relay board on my Roper range?

Typically, you'll need to remove the control panel or rear access panel using a screwdriver or nut driver. Refer to your range's service manual for specific instructions.

•What voltage should I expect to see on the communication wires between the main control board and the relay board?

The communication wires usually carry a low voltage DC signal, typically around 5V DC. Use a multimeter to check the voltage while the range is powered on (after safely verifying main power is disconnected during component access).

•Where can I find a wiring diagram for my specific Roper range model?

Wiring diagrams are often located inside the range itself, sometimes taped to the back panel or inside the control panel. You can also search online for the service manual for your specific model number, which usually includes a wiring diagram.
