Maytag Oven Error Code F-43

F-43 indicates an induction cooktop under voltage condition, classified as a Type 2 failure. The Induction Power Supply module has detected that the incoming AC voltage is insufficient for safe operation. The diagnostic threshold is 196V AC, and testing the outlet voltage determines whether the IPS module is faulty or the electrical supply is the root cause.

It is not recommended to continue operating the induction cooktop while this error is present. Running induction electronics under insufficient voltage can cause additional damage to the IPS module and other internal components. The oven's baking functions may still be available, but the induction cooktop should remain off until the fault is resolved.

Unplugging the range or disconnecting power can temporarily clear the F-43 code, but the error will return if the underlying cause is not corrected. If the IPS module is defective or the supply voltage remains below 196V, the fault will reappear once the cooktop attempts to operate. A reset alone is not a fix and should only be used as part of the diagnostic process.

Some steps are DIY-friendly, such as checking your circuit breaker and measuring the outlet voltage with a multimeter. If the voltage at the outlet reads above 196V AC, the IPS module needs replacement, which is a more advanced repair involving high-voltage components and is best handled by a qualified technician. If the voltage reads below 196V, you will need a licensed electrician to evaluate your home's electrical supply.

Repair costs vary depending on the root cause. If the issue is a faulty IPS module, parts and labor typically fall in the range of $150 to $400 or more depending on your location and the specific part cost. If the problem is with your home's electrical supply, electrician fees for diagnosing and correcting breaker or wiring issues generally range from $75 to $300 or higher.
