Never perform repairs to your range without first disconnecting the power supply. Electric ranges utilize a 240v, 30-amp power source, which is capable of producing lethal jolts. To disconnect the power, turn off the breaker in your home's service panel, or unplug the appliance from the wall outlet.
The ERC functions as the brain of oven, and controls all aspects of its operation. Often, a failure of the clock indicates a failure elsewhere in the electronic range control, and usually leaves the oven inoperable. The failure could be due to an electrical surge, or simply due to the age of the control. When the clock fails, it cannot be repaired, and instead must be replaced.
Replacement ERC modules are available from many appliance parts retailers. Before placing your order, locate the model number of your range, which is usually located on a sticker located on the door jamb or on the side or rear of the range. The model number will help ensure that the correct module for your specific appliance is purchased, as many modules only work correctly in the appliance they were specifically designed for.
To replace the ERC, you must first move the range away from the wall and remove the upper rear panel, which is secured using screws. Remove the old ERC by removing the screws securing it to the range. For easy installation, do not disconnect the wires from the rear of the old ERC right away. If necessary, transfer the overlay from the old ERC to the new ERC, and then secure the ERC to the range. Transfer the wires from the old ERC to the new ERC, and then reassemble the range.
