Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind: 

• Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
• Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
• Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
• 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.

How to troubleshoot the F14 error

Step 1 – Check the wire harness

1. Unplug the oven.
2. Look over the connections from the thermostat to the board. If you find any signs of damage (cracks, breaks, burn spots, corrosion), replace the wiring.
3. Use a multimeter to test for continuity from one end of the wire to the other. You should get continuity and your meter should beep if the wiring is good.

If the wiring is damaged or doesn’t have continuity, you’ll need to replace the wiring.

Step 2 – Check the temperature sensor

1. Find the temperature sensor on the back of the oven cavity.
2. Look over the contacts and wiring ends for debris or damage.
3. Use a multimeter to test the sensor’s resistance. You should get a reading between 1000 and 1100 ohms, but be sure to check the tech sheet for your model to see what yours should read. 

If the temperature sensor is damaged or gives an incorrect resistance reading, replace it with a new one.

Step 3 – Check the control board

If everything else looks good and passes testing, take a look at the control board for any damage, such as cracks or burn spots. 

If the board looks good and you’ve tested the heating element, temperature sensor, and wiring, then it’s likely that the control board has failed and needs to be replaced.
