Whirlpool Cooktop Error Code F-43 E-00

F-43 E-00 is a power supply error code generated by the power control board, classified as a Type 2 failure. It means the control board has detected a problem with the incoming 240-volt AC power supply. This can point to issues with the home's circuit breaker, supply wiring, terminal block connections, or the control board itself. The cooktop may disable functions until the underlying power issue is corrected.

You should not attempt to use the cooktop while this error code is active. A power supply error can indicate underlying electrical problems that pose a risk of damage to the appliance or, in cases involving wiring faults, a potential safety hazard. Disconnect the cooktop from power and address the electrical issue before resuming use.

Repair costs vary depending on the cause. If the issue is a tripped or failed circuit breaker, electrician fees typically range from $75 to $250 or more depending on the work required. Wiring repairs can fall in a similar range. If the power control board needs replacement, parts and labor combined can range from $150 to $400 or higher depending on the specific model and local labor rates.

Start by checking your home's circuit breaker panel for a tripped double-pole breaker and reset it if needed. Then verify that 240 volts AC is present at the cooktop's main incoming power connection using a multimeter. If voltage is correct at the terminal block, inspect all wiring and connections for damage or corrosion. If the wiring and power supply check out, the power control board may need to be replaced.

Cutting power to the cooktop at the circuit breaker for a few minutes may temporarily clear the code, but if the underlying power supply issue has not been corrected, the error will return. A reset alone is not a repair. The root cause, whether it is a wiring problem, a weak breaker, or a failing control board, must be identified and fixed.
