What 940 means on a GE range

Error code 940 on a GE range is specific to the RC15 control board and indicates that one or more keys on the oven control keypad have been detected in a continuously pressed or stuck state for 100 seconds or longer. The control board monitors key input signals in real time, and when any single key registers an uninterrupted closed contact for that 100-second threshold, the board flags the fault and displays the 940 code. This is a keypad-level detection failure, not a control board processing error.

The most common root cause is physical contamination or damage to the membrane keypad overlay. Grease, food residue, or liquid that seeps beneath the keypad surface can create a constant electrical contact on a specific key zone, mimicking a pressed key indefinitely. Over time, the adhesive backing of the membrane can also delaminate and cause the keypad to press against the underlying contacts without any external force. Less commonly, a failed or shorted ribbon cable connector between the keypad and the RC15 board can produce the same false-input signal.

The 940 code will clear automatically once the stuck key condition is resolved. If power cycling the range temporarily clears the display but the code returns, the underlying physical or electrical fault in the keypad assembly is still present and needs to be addressed directly. Technicians should inspect the keypad surface for visible damage or residue, check the ribbon cable seating, and verify whether a specific key on the display appears highlighted or unresponsive during normal operation.

Common causes of 940

  1. 01

    Contaminated keypad membrane

    Wiring / connection

    Food residue, grease, or liquid seeping beneath the membrane keypad creates a constant electrical contact on one or more key zones, making the control board read the key as continuously pressed. Inspect the keypad surface for sticky spots, discoloration, or visible spills around individual buttons.

  2. 02

    Delaminated or warped keypad overlay

    Part replacement

    The adhesive backing of the membrane keypad can fail over time, allowing the overlay to bow inward and press against the contact layer beneath it without any user input. Look for bubbling, peeling edges, or raised sections on the keypad surface.

  3. 03

    Physically damaged key zone

    Part replacement

    A cracked or dented keypad caused by impact or excessive force can permanently depress a contact point, triggering the 100-second stuck key threshold. Check the keypad for visible cracks or deformed areas corresponding to a specific button.

  4. 04

    Loose or faulty ribbon cable connection

    Wiring / connection

    The ribbon cable connecting the keypad membrane to the RC15 control board can become unseated or develop a short, producing a false continuous key signal. Inspect the ribbon cable connector at both ends for proper seating, damage, or corrosion.

  5. 05

    Failed RC15 control board input circuit

    Part replacement

    In rare cases, the key input circuitry on the RC15 board itself can fail and incorrectly report a stuck key even when the keypad is undamaged. This is the least likely cause and should only be considered after the keypad and ribbon cable have been ruled out.

Frequently asked questions about 940

What does 940 mean on a GE range?
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.
Will resetting the power clear the 940 error code on my GE range?
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.
Is it safe to use my GE range while the 940 error code is displayed?
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.
How do I fix the 940 error code on my GE range?
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.
How much does it cost to repair a GE range showing a 940 error code?
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.
