What All LEDs flash means on a Maytag cooktop

When all LEDs flash simultaneously on a Maytag cooktop, the control board is signaling one of two fault conditions: an over-temperature event or the detection of multiple keys pressed at the same time, which typically indicates a shorted key on the touch control panel. In either case, the cooktop will disable all element operation and emit continuous 3-short-beep audible alerts. This is a protective shutdown designed to prevent damage to the cooktop or a potential safety hazard from uncontrolled heating.

The over-temperature condition occurs when a temperature sensor detects heat levels beyond the acceptable operating threshold. Verifying sensor resistance is the first diagnostic step because a faulty or out-of-range sensor can falsely trigger this fault even when actual temperatures are within normal limits. A sensor reading outside the expected resistance range points directly to a failed sensor component rather than a genuine overheating event.

The shorted key condition occurs when the control board interprets simultaneous input from multiple touch points on the keypad, which can result from physical damage to the keypad surface, moisture or debris bridging contact points, or an internal failure on the control board itself. If sensor resistance checks out as normal and the fault persists, the control board is the next component to address, as it may be misreading inputs or generating the fault condition internally.

Common causes of All LEDs flash

  1. 01

    Shorted or stuck touch key on control panel

    Part replacement

    A damaged, wet, or debris-covered keypad can cause the control board to detect multiple keys pressed simultaneously, triggering the all-LED flash fault. Inspect the keypad surface for visible damage, moisture, or buildup around the touch zones.

  2. 02

    Out-of-range temperature sensor resistance

    Part replacement

    A failing temperature sensor can report a false over-temperature condition to the control board, causing the fault even when the cooktop is not actually overheating. Measuring the sensor's resistance with a multimeter and comparing it to the expected value will confirm whether the sensor is faulty.

  3. 03

    Actual over-temperature event

    Wiring / connection

    If a cooking zone genuinely overheated, such as from a dry pan or blocked ventilation, the sensor may have triggered a legitimate shutdown. Allow the cooktop to cool completely and check whether the fault clears before proceeding with further diagnostics.

  4. 04

    Moisture or debris on the control panel

    Wiring / connection

    Liquid spills or food debris on the touch surface can bridge multiple key contacts and simulate a shorted key condition. Thoroughly clean and dry the control panel surface and attempt to reset the cooktop.

  5. 05

    Failed control board

    Part replacement

    If sensor resistance is within the normal range and the keypad surface is clean and undamaged, the control board itself may be generating the fault internally. Replacing the control board is the recommended next step when all other causes have been ruled out.

Frequently asked questions about All LEDs flash

What does All LEDs flash mean on a Maytag cooktop?
All LEDs flashing on a Maytag cooktop indicates either an over-temperature condition or a shorted key detected on the control panel. The cooktop disables all element operation and produces continuous 3-short audible beeps as a safety response. The two most common causes are a faulty temperature sensor and a damaged or contaminated touch keypad.
Can I fix the All LEDs flash error myself, or do I need a technician?
Some causes, such as moisture or debris on the keypad, can be addressed by cleaning the surface and allowing the cooktop to cool and reset. However, diagnosing a faulty temperature sensor requires a multimeter and basic knowledge of resistance testing. Replacing a control board involves working near electrical components, so if you are not comfortable with appliance repair, a qualified technician is the safer option.
Is it safe to use my Maytag cooktop while all LEDs are flashing?
No, the cooktop is designed to disable all element operation when this fault is active, so it will not allow cooking while the LEDs are flashing. Do not attempt to bypass the fault condition, as the alert exists to protect against potential overheating or uncontrolled element behavior. Resolve the underlying cause before resuming use.
Will resetting the cooktop clear the All LEDs flash error?
A reset, such as cycling power at the circuit breaker, may temporarily clear the fault if it was triggered by a one-time event like a genuine overheating episode. However, if the root cause is a failed temperature sensor, a shorted key, or a faulty control board, the error will return. A reset alone is not a repair and should be followed by proper diagnostics.
How much does it cost to repair an All LEDs flash fault on a Maytag cooktop?
Repair costs vary depending on the root cause. Cleaning the keypad costs nothing beyond your time, while a replacement temperature sensor typically runs in the range of $20 to $60 for the part. A new control board is generally the most expensive repair, with parts commonly ranging from $80 to $250 or more, plus labor if a technician is needed.
