What E25 means on a Frigidaire cooktop

The E25 error code on a Frigidaire cooktop indicates that the main power key sensor has been detected as defective. This sensor is part of the capacitive or resistive touch control interface integrated into the cooktop's control panel. The main power key sensor is responsible for detecting when the user initiates or terminates operation of the entire cooktop. When the control board continuously reads an out-of-range or erratic signal from this sensor, it triggers E25 to prevent unsafe or unintended operation.

The touch control assembly on these cooktops combines the power key sensor and the right front cook zone controls into a single integrated module. This means a failure in the main power key sensor is physically located within the same touch panel unit that manages the right front burner zone. Causes of sensor failure include moisture or liquid infiltration beneath the touch surface, physical damage or cracking of the touch panel, contamination from cooking residue that alters sensor conductivity, or internal component degradation within the touch control circuit itself.

Because the sensor and its associated electronics are embedded within the touch control assembly, individual sensor repair is not practical. The diagnostic path points directly to replacing the main power and right front cook zone touch control module as a complete unit. Attempting to continue operation with a defective power key sensor may result in the cooktop being unable to power on or off reliably, which is a safety concern that warrants prompt attention.

Common causes of E25

  1. 01

    Failed touch control module

    Part replacement

    The internal electronics within the touch control assembly can degrade over time, causing the power key sensor to send faulty signals. This is the most likely cause and the fix indicated by the diagnostic step.

  2. 02

    Moisture or liquid contamination

    Part replacement

    Spills or steam that seep beneath the touch panel surface can short or corrode the sensor contacts, triggering a defective sensor reading. Inspect the panel surface for signs of liquid intrusion or residue near the power key area.

  3. 03

    Cooking residue buildup on touch surface

    Wiring / connection

    Heavy grease or food residue accumulation directly over the power key sensor area can interfere with capacitive sensing. Clean the surface thoroughly and check whether the error clears before proceeding to replacement.

  4. 04

    Physical damage to the touch panel

    Part replacement

    Cracks, chips, or scratches on the glass or overlay surface above the power key sensor can disrupt sensor function. Visually inspect the panel for any visible damage in the power key zone.

  5. 05

    Loose or damaged wiring connection to touch control

    Wiring / connection

    A loose ribbon cable or harness connector between the touch control module and the main control board can cause erratic sensor readings. Inspect the wiring connections to the touch control assembly before committing to a full module replacement.

Frequently asked questions about E25

What does E25 mean on a Frigidaire cooktop?
E25 indicates that the main power key sensor in the cooktop's touch control panel has been detected as defective. The control board is receiving an invalid or out-of-range signal from the sensor responsible for powering the cooktop on and off. This code points to a fault within the main power and right front cook zone touch control module.
Can I fix the E25 error myself?
A knowledgeable DIYer can address this error by first cleaning the touch panel surface and checking wiring connections to the touch control module. If those steps do not resolve the issue, the touch control assembly will need to be replaced, which involves disconnecting power, accessing the control panel, and swapping in a new module. If you are not comfortable working with appliance electronics, a qualified technician is recommended.
Is it safe to use my Frigidaire cooktop while E25 is displayed?
Operating the cooktop with an active E25 error is not recommended. A defective power key sensor means the cooktop may not respond reliably to on and off commands, which presents a safety risk. It is best to stop using the cooktop until the touch control module has been inspected and repaired.
Will resetting the cooktop clear the E25 error?
Resetting the cooktop by cutting power at the breaker for a few minutes may temporarily clear the E25 display, but the code will return if the underlying sensor fault is still present. A reset does not repair a defective touch control sensor. Persistent E25 errors require physical inspection and likely replacement of the touch control module.
How much does it cost to repair an E25 error on a Frigidaire cooktop?
Repair costs depend on whether you hire a technician or perform the repair yourself. The touch control module part itself typically ranges from around 80 to 200 dollars depending on the specific cooktop model. Professional labor to diagnose and replace the part can add another 100 to 200 dollars, bringing total repair costs to a range of roughly 180 to 400 dollars.
