Frigidaire Cooktop Error Code E54

E54 indicates a break in the temperature sensor circuit for the right rear heating element. The generator circuit board is not receiving a valid signal from that sensor, so it flags the error and disables the element. The issue typically points to a loose connection, damaged wiring, or a failed sensor.

The right rear element will typically be disabled when E54 is active, which limits your cooktop's functionality. While the other elements may still operate, continuing to use the appliance with an unresolved sensor fault is not recommended, as the board cannot properly monitor or regulate the affected element. Address the fault before relying on that burner.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, there may be no parts cost at all. Replacing a temperature sensor typically runs in the range of $20 to $60 for the part. If the generator circuit board needs replacement, parts alone can range from $80 to $200 or more, with additional labor costs if a technician performs the repair.

Some causes of E54 are approachable for a confident DIYer. Checking and reseating the sensor connector at the generator circuit board is a straightforward first step that requires no special tools. However, testing sensor continuity, inspecting internal wiring, or replacing the circuit board are tasks better suited to someone comfortable working with appliance electronics and disassembly.

A power reset by turning off the circuit breaker for one to two minutes may temporarily clear the displayed code, but the error will return if the underlying cause is not repaired. The sensor break condition must be physically corrected, whether that means reseating a connector, replacing the sensor, or repairing the wiring, before the code is truly resolved.
