The role of the power card is to supply all the organs of the device through the small components called relays and found on the card. Each relay performs a specific function. You can change the electronic card if:

  • the oven does not heat up
  • the oven does not turn on
  • no cooking program starts
  • touch screen unresponsive
  • there is a display problem,
  • the fan does not turn,
  • the resistance is no longer powered

As a precaution, it is advisable to change the complete power board if you have a defective component on it.

Some ovens have several electronic boards: a power board and a control board. The role of the display board is to establish and display the information to guide you in cooking. It should be replaced when you have:

  • a touch problem
  • the signaling beep that no longer works
  • a missing segment on the display
  • a contrast problem

The power board and display board of a cooker oven are located above and inside the oven casing.

Highly visible, accessible and generally in a central position above the device, the power card is the largest card, the one on which many components are connected.

The power and display card, or control board, of an oven is essentially the oven’s brain. It controls every function, from the timer and temperature settings to the self-cleaning cycle. If your oven isn’t working properly, it could be due to a problem with the power and display card. In this guide, we will walk you through how to replace it.

Disclaimer: Changing the power and display card of an oven involves working with electricity. It should only be done by individuals who are comfortable working with electronics. Always disconnect the oven from the power source before beginning. If you’re unsure or uncomfortable performing this task, or if your oven’s warranty still applies, hire a professional.

Tools You Might Need

  1. Replacement power and display card (ensure it’s compatible with your oven model)
  2. Screwdriver
  3. Camera or pen and paper (to note the connections)

Step-by-Step Guide

Step 1: Disconnect the Oven

Before you begin, ensure that the oven is unplugged or that the circuit breaker is switched off if the oven is hardwired into your home.

Step 2: Locate the Power and Display Card

The power and display card is usually located behind the control panel of the oven. To access it, you will need to remove the back panel of the oven, which is typically held in place by a few screws.

Step 3: Take a Picture or Note the Connections

Before removing the old power and display card, take a picture or make a note of the connections. This will be extremely helpful when installing the new card.

Step 4: Remove the Old Power and Display Card

Disconnect the wires attached to the power and display card by pulling them off gently. Then, remove the screws holding the card in place. Once the screws are removed, you should be able to lift the card out of its slot.

Step 5: Install the New Power and Display Card

Place the new power and display card in the same slot where the old one was located. Using the picture or notes you took earlier, reconnect the wires to the correct terminals on the card. Once the wires are connected, secure the card with the screws.
