Kenmore Range Error Code 72

Error code 72 on a Kenmore range indicates a power supply defect in the Induction Housing Assembly on the right side of the cooktop. The range has detected an abnormal power condition affecting the right-side cooking zones. Diagnosis begins with testing all cables and connections on the Large Filter Circuit Board, which conditions power to that section of the range.

You should avoid using the right-side induction cooking zones while error code 72 is active, as the fault indicates a power supply defect in that section of the range. Continuing to operate the affected zones with a known power supply fault could potentially worsen component damage. Left-side zones may function normally, but the range should be inspected and repaired promptly.

Repair costs for error code 72 vary depending on the root cause. If only a loose cable connection is found, a service call fee alone may cover the repair, typically in the range of $75 to $150. If the Large Filter Circuit Board or the Induction Housing Assembly requires replacement, parts plus labor costs can range from $200 to $500 or more depending on parts availability and local labor rates.

Some causes of error code 72, such as a loose cable connector, can be addressed by a knowledgeable DIYer who is comfortable working inside the appliance after disconnecting power. However, diagnosing and replacing components like the Large Filter Circuit Board or the Induction Housing Assembly involves working with high-voltage electronics and is best handled by a qualified appliance technician. Always disconnect the range from power before inspecting any internal components.

A reset by disconnecting the range from power for several minutes may temporarily clear the display, but error code 72 will return if the underlying power supply defect is not corrected. The fault is hardware-based, involving the wiring, connectors, or circuit board components in the right-side induction system. A lasting repair requires identifying and fixing the root cause rather than relying on a reset.
