Frequently Asked Questions
•What is the location of the MCU on the main control board?
The MCU is typically located near the center of the main control board. Look for a large chip with a prominent manufacturer logo and part number. Consult the schematic diagram for its exact location.
•What voltage should I expect to measure at the MCU?
You should expect to measure either 3.3V DC or 5V DC at the MCU's power pins. Refer to the datasheet for the specific MCU to identify the correct pins and voltage.
•If the firmware update fails repeatedly, is a board replacement the only option?
While a board replacement is often the solution, attempt a factory reset first. If that fails, and you have the appropriate equipment, you could attempt to re-flash the firmware directly via JTAG or similar interface. However, this requires specialized knowledge and equipment and carries a risk of further damaging the board. It's best to consult GE Support for confirmation.
