GE Range Error Code 940

Error code 940 on a GE range means the RC15 oven control board has detected that one of the keypad keys has been stuck in a pressed position for 100 seconds or longer. This is a keypad input fault specific to ranges equipped with the RC15 control. The code appears on the oven display and will clear automatically once the stuck key condition is resolved. If the code keeps returning, a physical or electrical problem with the keypad assembly needs to be addressed.

A 940 error code indicates a stuck key on the control panel, which can interfere with normal oven operation and input response. Using the range while this fault is active is not recommended because the stuck key may prevent you from entering commands correctly or canceling functions. It is best to address the keypad issue before continuing to use the oven to avoid unintended operation.

Repair costs depend on what is causing the stuck key condition. If only cleaning is needed, there may be no parts cost at all. A replacement keypad membrane assembly typically falls in the range of $30 to $100 for parts depending on the model, plus labor if a technician is hired. If the RC15 control board itself has failed, board replacement costs are generally higher, often ranging from $150 to $350 or more for parts and labor combined.

A power reset may temporarily clear the 940 code if the stuck key condition resolves during the reset cycle. However, if the underlying cause is contamination, a damaged keypad, or a faulty ribbon cable connection, the code will return once the control board detects the stuck key signal again. The code is designed to clear on its own when the fault condition is gone, so a persistent 940 error points to a physical problem that needs direct inspection and repair.

Start by inspecting the keypad surface for any visible residue, spills, or damage that could be holding a key in the pressed position. Cleaning the keypad surface carefully and allowing it to dry may resolve the issue if contamination is the cause. If the keypad is physically damaged or delaminated, replacing the membrane keypad assembly is typically required. If the keypad appears intact, check that the ribbon cable connecting the keypad to the RC15 board is fully seated and undamaged.
