Frigidaire Cooktop Error Code E7

E7 on a Frigidaire cooktop indicates that the left rear zone key sensor has been detected as defective by the control system. The touch control responsible for the left rear burner is sending an invalid signal or no signal at all. This fault disables or disrupts that cooking zone and requires attention to the left side cook zones touch control assembly.

Using the cooktop with an active E7 error is not recommended. A defective key sensor can cause the left rear zone to behave unpredictably, either failing to respond or potentially activating in an unintended way. It is best to avoid using the affected zone until the touch control has been inspected and repaired.

Repair costs vary depending on the specific cooktop model and whether you hire a technician or do it yourself. The left side cook zones touch control assembly typically falls in the range of $80 to $200 for the part alone. Adding professional labor, total repair costs can range from $150 to $350 or more depending on your location and service rates.

A knowledgeable DIYer can start by cleaning the touch surface thoroughly and checking for any visible damage or loose connectors. However, if the internal sensor has failed, the left side cook zones touch control assembly will need to be replaced, which involves disconnecting power, accessing the control, and installing the new part. If you are not comfortable working with appliance electronics, a qualified technician should perform the replacement.

Resetting the cooktop by cutting power at the breaker for a few minutes may temporarily clear the E7 error, but if the touch control sensor has physically failed, the code will return once the unit powers back on. A reset is useful for ruling out a one-time glitch, but a recurring E7 code confirms that the touch control assembly needs to be replaced.
