Whirlpool Range Error Code F6E3

F6E3 means the Maxwell or MRC control system has detected an over-temperature condition in the warming drawer. The control board monitors warming drawer temperatures and triggers this fault when the temperature exceeds its acceptable limit, whether from an actual overheating event or a sensor or control board failure reporting bad data.

Start by pressing CANCEL>CANCEL>START to enter Diagnostics Mode and confirm the F6E3 code is active. Once confirmed, unplug the range and replace the control board, which is Whirlpool's specified repair for this fault. Before assuming the board is the only issue, inspect the warming drawer wiring harness and temperature sensor for visible damage or shorts, since a faulty sensor can also trigger this code.

Pressing Cancel will clear the display temporarily, but F6E3 will return if the underlying problem is not fixed. This code is not caused by a power glitch or a one-time sensor spike in normal operation. Whirlpool's diagnostic procedure requires entering Diagnostics Mode to verify the fault and then replacing the control board. A simple reset does not resolve the over-temperature condition in the warming drawer circuit.

You should not use the warming drawer while F6E3 is active, since the code indicates the drawer is either genuinely overheating or the control system cannot regulate it properly. The main oven burners may still function, but operating the warming drawer in this state risks further component damage or a burn hazard. Unplug the range and address the fault before using the warming drawer again.

A replacement Maxwell or MRC control board for a Whirlpool range typically costs between $150 and $350 for the part alone, depending on the specific model. If you hire a technician, expect an additional $100 to $200 in labor. If the root cause turns out to be the warming drawer temperature sensor or wiring harness rather than the board, parts cost drops significantly, often under $50.
