Keep safety first

Your safety should always be the top priority when performing any appliance repair.

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by preventing any risk of electric shock.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can clearly see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.
• Consider wearing safety glasses and/or a dust mask when working with chemicals, dust, or a large amount of debris to prevent irritation or injury.

Troubleshooting instructions

Step 1- Inspect the wire harness

The wiring harness is responsible for carrying signals between components. Let’s take a close look at it to see if we can spot any issues.

1. Make sure the range is turned off and unplugged from the power outlet.
2. Disconnect the wire harness from all parts.
3. Check each connection point for signs of damage, looseness, or corrosion. If you find any, replace the harness.
4. If the harness looks good, set a multimeter to the continuity setting (looks like a sideways WiFi symbol) and use the two meter leads to test along the entire length of each wire.

If there’s a break or short detected here, replace the harness. If the wire harness checks out OK, move on to the next steps.

Step 2- Check the boards

LIVE VOLTAGE WARNING: For these tests, the range needs to be plugged in and powered on. Please be very careful to protect yourself from electric shock, which has the potential to cause serious injuries. Don’t ever test live voltage if you’re uncomfortable using a multimeter.

1. Make sure the range is plugged in and turned on.
2. From the back of the range, find the control board on the right side. Notice that the wire harness to this board has four wires and five pins.
3. Disconnect the wire harness plug from the board.
4. Set your multimeter to DC voltage.
5. Measure the voltage drop between pins one and two.
6. Check the meter reading.

If the reading is between 4 volts DC and 12 volts DC, the control board is good.

If the reading is below 4 volts DC or above 12 volts DC, you’ll need to replace the control board to fix the F5 error.

Preventive maintenance

To prevent the pesky F5 error from popping up on your range:

• Wipe up spills and splatters as soon as they happen to prevent sensitive parts from debris buildup and damage.
• Clean your range at least once every six months or more, depending on how much you use it.
• Avoid overloading circuits to prevent electrical issues.
