What 8 LEDs flash means on a Maytag cooktop

When a Maytag cooktop displays the 8 LEDs flash condition, it indicates either an open temperature probe circuit or an open input on the power board. The electronic control enters a locked state in response to this fault, and notably, no audible alarm is triggered. This makes the flashing LED pattern the only visual indicator that a fault condition exists. The temperature probe is a resistive sensor that the control board monitors continuously to regulate heat output across the cooking zones.

The root of this fault typically lies in a break in the circuit between the temperature probe and the power board. An open circuit can result from a failed probe with an internal wire break, a disconnected or corroded connector, or a damaged wiring harness between the probe and the board. To begin diagnosis, the probe resistance should be measured with a multimeter. A probe showing infinite resistance or an out-of-specification reading confirms an open or failed sensor. Connector integrity at both the probe end and the board end should also be inspected for corrosion, bent pins, or loose seating.

If the wiring and probe connections check out and the probe resistance measures within specification, the fault may originate at the power board input itself, where the board can no longer properly read the incoming sensor signal. In this scenario, the power board requires replacement to restore normal operation. Since no audible alarm accompanies this fault, technicians should be alert to this LED pattern during routine diagnostics, as it can be overlooked without a careful visual check of the control panel.

Common causes of 8 LEDs flash

  1. 01

    Failed temperature probe

    Part replacement

    The temperature probe may have an internal wire break, causing an open circuit that the control board cannot read. Measuring the probe resistance with a multimeter will reveal an infinite or out-of-range reading if the probe has failed.

  2. 02

    Disconnected or loose probe connector

    Wiring / connection

    The wiring connector between the temperature probe and the power board may have come loose or partially unplugged. Inspect both the probe-side and board-side connectors for secure seating and physical damage.

  3. 03

    Corroded or damaged connector pins

    Wiring / connection

    Corrosion or bent pins at the probe connector can interrupt the circuit even if the connector appears seated. Visual inspection and cleaning or reseating of the connector may resolve the fault.

  4. 04

    Damaged wiring harness

    Part replacement

    The wiring between the temperature probe and the power board may have a break, burn, or pinch point along its length. A continuity test of the harness wires can confirm whether the harness is the source of the open circuit.

  5. 05

    Faulty power board input

    Part replacement

    If the probe and all wiring test correctly, the open input condition may be internal to the power board itself. In this case, the power board requires replacement to clear the fault.

Frequently asked questions about 8 LEDs flash

What does 8 LEDs flash mean on a Maytag cooktop?
The 8 LEDs flash condition on a Maytag cooktop indicates an open temperature probe circuit or an open input on the power board. The electronic control locks itself in response to this fault to prevent uncontrolled operation. No audible alarm accompanies this fault, so the flashing LEDs are the only indicator. Diagnosis begins with checking the resistance of the temperature probe and inspecting the wiring and connectors.
Can I fix the 8 LEDs flash error on my Maytag cooktop myself?
A knowledgeable DIYer can perform the initial diagnostic steps, including inspecting connectors and measuring probe resistance with a multimeter. If the probe is open or out of specification, replacing it is a straightforward repair. However, if the fault points to the power board, board replacement involves working with high-voltage components and may be better suited to a qualified technician.
Is it safe to use my Maytag cooktop while the 8 LEDs are flashing?
No, the cooktop should not be used while this fault is active. When 8 LEDs flash, the electronic control is locked, which means normal cooking operation is disabled. Attempting to bypass or ignore this fault could result in improper temperature control. The underlying issue should be diagnosed and repaired before resuming use.
Will resetting my Maytag cooktop clear the 8 LEDs flash error?
A power reset by unplugging the cooktop or cycling the circuit breaker may temporarily clear the LED display, but the fault will return if the underlying cause is not corrected. The open probe or open board input condition must be resolved through component testing and repair or replacement. Resetting alone is not a fix.
How much does it cost to repair the 8 LEDs flash error on a Maytag cooktop?
Repair costs vary depending on whether the temperature probe, the wiring harness, or the power board needs replacement. A temperature probe replacement is generally the least expensive repair, with parts typically ranging from $20 to $80 depending on the model. Power board replacement is more costly, with parts often ranging from $100 to $300 or more, plus labor if a technician performs the work.
