GE Cooktop Error Code E5

E5 indicates an internal electronic failure on the filter board of the cooktop. The filter board conditions incoming AC power before it reaches the main control electronics, and when the self-diagnostic system detects a failure in this component, it displays E5 and disables operation. The code may be caused by a defective filter board or by insufficient incoming AC voltage to the home.

A power reset, such as switching off the circuit breaker for 30 seconds and restoring power, may temporarily clear the display, but E5 will return if the underlying filter board failure or voltage problem is not corrected. The code is tied to a hardware fault, not a software glitch, so resetting alone is not a fix.

Repair costs depend on whether the issue is a voltage problem at the home, which may require an electrician and range from modest diagnostic fees to larger electrical repairs, or an actual filter board replacement. Filter board parts and professional labor combined typically fall in the range of $150 to $400 depending on the specific cooktop model and local labor rates.

The first step you can do yourself is verifying that your home's AC supply voltage is above 208 VAC using a voltmeter at the cooktop's receptacle or junction box. If voltage is adequate, the filter board needs to be replaced, which involves working inside the cooktop with line voltage present. This repair is best handled by a qualified technician unless you are comfortable with high-voltage appliance work.

No. When E5 is active, the cooktop typically locks out cooking functions to protect both the user and the downstream electronics from potential damage caused by unfiltered or irregular power. Attempting to bypass or ignore this fault is not recommended. Leave the unit off until the filter board and supply voltage have been properly evaluated.
