Frigidaire Cooktop Error Code E55

E55 indicates a break in the temperature sensor circuit for the right front heating element. The cooktop's generator circuit board is not receiving a valid signal from that sensor. As a result, the right front element is disabled until the fault is corrected. The issue may be a loose connector, a failed sensor, or damaged wiring.

The right front element will typically be disabled when E55 is active, which prevents that specific burner from operating. The remaining elements may still function, but you should not attempt to bypass the fault or ignore it. Operating cooking equipment with a compromised temperature sensing system carries a risk of uncontrolled heating, so the fault should be diagnosed and repaired promptly.

Repair costs vary depending on which component has failed. A replacement temperature sensor typically runs in the range of $20 to $60 for the part. A generator circuit board is a more expensive component, often ranging from $100 to $250 or more. Adding a technician's labor for diagnosis and replacement, total repair costs can range broadly from around $100 to $400 depending on the fault and your location.

A knowledgeable DIYer can start by disconnecting power to the cooktop, accessing the generator circuit board, and checking that the right front element sensor connector is fully seated. If reseating the connector does not clear the code, testing the sensor and wiring for continuity requires a multimeter and comfort working with appliance internals. Board replacement, if needed, is more involved and may be better suited for a qualified technician.

Resetting the cooktop by cutting power at the breaker for a few minutes may temporarily clear the displayed code, but if the underlying sensor break still exists, the error will return when the unit powers back on. A reset alone does not repair a broken sensor, damaged wiring, or a failed board. The root cause must be addressed for the code to stay cleared.
