Replacing the Control on a Kitchen Range
This advice is for GAS or ELECTRIC ranges equipped with a rear panel display. The electronic control board on these ranges not only display the clock and timer functions, but also control all the oven features. If the board fails, you will experience a loss of some, or all of the oven features. Due to the safety design of new generation appliances, the board needs to replaced to restore the oven features.
The control board is commonly referred to as the Electronic Range Control (ERC) or Electronic Oven Control (EOC). Both terms are often used interchangeably.
Replacing an ERC/EOC is not a difficult repair and can easily be accomplished by the average do-it-yourselfer. To avoid retail mark-up, parts can generally be ordered on line at discounted prices. If you decide to order the part and wish to repair this on your own, follow these steps:
1. UNPLUG the range. Dangerous voltage is still present inside even with the range turned off.
2. Pull the range away from the wall and turn the unit around so you can access the rear panel.
3. Remove the screws on the back of the operator console.
4. Carefully disconnect the connector plugs to the ERC/EOC. Take note of how they are connected, so that you can reinstall them correctly.
NOTE: The connectors are usually color coded with the colors printed on the circuit board. However, if the colors are not printed on the board, write them down. (A digital camera also comes in real handy for this).
5. With the connectors removed, remove the mounting screws to the ERC/EOC and the assembly will come out.
NOTE: Most replacement ERC/EOC boards do not come with the overlay. This is the plastic pre-printed number display. The overlay can easily be peeled off and re-used. Some of these overlays are not cheap, so replacement is not always necessary. Just make sure you properly orient the overlay so that you don't inadvertently place it on the new board upside down. If your existing overlay is damaged, you will need to order separately.
6. Install new ERC/EOC using the steps provided in reverse order. Minimize handling the new circuit board with your bare hands to avoid causing Electro-Static damage to the board.
NOTE: This is static electricity that can build up in the human body. There is enough voltage in most static charges that can easily damage sensitive components on circuit boards. Handle the edges of the circuit board and avoid touching the surface area when possible.
If you have any questions about this repair, or if you need recommendations on where to purchase replacement parts, please let me know. I hope this information is found to be helpful.
