Kenmore Range Error Code 31

Error code 31 on a Kenmore induction range indicates an internal generator synchronization error in the left side of the Induction Housing Assembly. This fault affects the left side cooking zones and disables them until the issue is resolved. The error points to a problem with the left side generator circuit board or the cables and connections associated with it.

When error code 31 is active, the left side cooking zones are disabled by the control system as a protective measure, so those specific burners should not operate. The right side of the range may still function, but you should not attempt to bypass or ignore the fault. Have the issue diagnosed and repaired before relying on the affected zones.

Repair costs vary depending on whether the issue is a simple connection problem or requires replacing the left side generator circuit board. If only cable reseating is needed, costs may be limited to a service call fee, typically in the range of $75 to $150. If the generator circuit board requires replacement, parts and labor combined can range from $200 to $500 or more depending on the specific model and local labor rates.

A knowledgeable DIYer can start by inspecting and reseating the cable connections on the left side generator circuit board, which is the first recommended diagnostic step. If connections appear secure and undamaged but the error returns, further diagnosis or board replacement will likely require comfort working with high-voltage induction components. If you are not experienced with induction range electronics, it is advisable to contact a qualified appliance technician.

Resetting the range by cycling power at the breaker may temporarily clear the display, but if the underlying generator synchronization fault is still present, the error will return when the left side zones are used. A power reset does not repair the root cause, which is a hardware issue with the left side generator circuit board or its connections. A proper inspection and repair are needed for a lasting fix.
