Kenmore Range Error Code 30

Error code 30 on a Kenmore range means the control system has detected an AC input voltage that is too high at the left-side Induction Housing Assembly. This is a protective fault that shuts down the affected cooking zones to prevent damage to the induction electronics. The first diagnostic step is to measure the incoming voltage at the Large Filter Circuit Board terminals X1/X2 and X4/X5, where the reading should be 240VAC. A significantly elevated reading points to a supply or wiring issue.

Cycling the range's circuit breaker or disconnecting power may temporarily clear code 30, but the error will return if the underlying cause has not been corrected. If the house voltage is genuinely running too high, or if the Large Filter Circuit Board or Induction Housing Assembly has a fault, the code will reappear once the unit powers back up. A reset is only a useful diagnostic step to confirm whether the fault is persistent or intermittent, not a permanent fix.

Repair costs vary depending on the root cause. If the fault is a utility overvoltage or a wiring connection issue, costs may be limited to an electrician's service call, typically in the range of $75 to $200. If internal parts are needed, a Large Filter Circuit Board or Induction Housing Assembly replacement plus labor can bring total repair costs to anywhere from $200 to $600 or more, depending on parts availability and local labor rates.

No, it is not recommended to continue using the range while error code 30 is active. The code indicates a potentially damaging overvoltage condition at the left-side cooking zones, and operating the induction system under these conditions could cause permanent damage to the inverter boards or other internal components. The range should remain unplugged or turned off at the breaker until the voltage supply and internal components have been properly inspected.

Begin by measuring the AC voltage at the Large Filter Circuit Board between terminals X1/X2 and X4/X5 using a true-RMS multimeter. If the voltage exceeds 240VAC, contact your utility company and a licensed electrician to address the supply issue. If voltage is within spec, the fault likely lies with the Large Filter Circuit Board or the left-side Induction Housing Assembly, either of which may need to be replaced. Loose or corroded wiring connections throughout the supply path should also be inspected and corrected.
