Kenmore Range Error Code 33

Error code 33 on a Kenmore range indicates a power supply defect in the Induction Housing Assembly affecting the left side cooking zones. The control system has detected an abnormal condition in the power delivery path to those burners. The first step in diagnosing this is testing all cables and connections at the Large Filter Circuit Board. Left-side induction zones may be non-functional until the fault is resolved.

A power supply defect in the induction housing assembly can indicate a damaged component or compromised wiring, which carries a risk of further electrical damage or, in severe cases, a fire hazard. It is best to avoid using the left-side cooking zones until the fault has been diagnosed and repaired. Right-side zones may still function, but using the appliance with an active fault code is not recommended until the root cause is identified.

Repair costs depend on the root cause. If the fix is simply reseating a loose connector, there may be minimal cost beyond a service call fee, which typically ranges from $75 to $150. If the Large Filter Circuit Board needs replacement, parts alone can range from $80 to $250 or more depending on availability, plus labor. A full left-side induction housing assembly replacement would be at the higher end of the cost range, potentially $200 to $500 or more for parts and labor combined.

A knowledgeable DIYer can start by unplugging the range and carefully inspecting all cable connections at the Large Filter Circuit Board for looseness or corrosion, which are common and straightforward fixes. However, if the fault involves a failed filter board or induction module assembly, those repairs require comfort working with high-voltage components and sourcing the correct replacement parts. If you are not experienced with induction appliance internals, a qualified technician is the safer option.

Power-cycling the range by unplugging it for a few minutes and restoring power may temporarily clear the error code, but if the underlying power supply defect remains, the code will return when the induction system is activated. A reset is useful for confirming whether the fault is intermittent, but it does not repair failed components, damaged wiring, or a faulty filter board. Persistent return of the code means physical inspection and repair are required.
