GE Oven Error Code F41

The F41 code means the lower oven machine control board has detected a short circuit in the meat probe circuit. The board monitors resistance on connector J300 pins 3 and 4 and expects to see 30k-50k ohms with a probe installed or an open circuit with no probe present. When the resistance falls below this range, the board flags F41 to alert you to a problem in the probe wiring, receptacle, or the probe itself.

The oven may still function for basic baking and broiling since F41 is specific to the meat probe circuit, not the main heating elements. However, you will not be able to reliably use the meat probe feature, and in some control configurations the error may prevent normal oven operation entirely. It is reasonable to continue light use while sourcing parts, but the fault should be repaired before relying on the probe for food safety.

Not always. The F41 code points to a short in the meat probe circuit, which includes the probe, the wiring harness, and the receptacle inside the oven cavity. GE's first recommended test is to measure resistance at the machine control board's J300 connector rather than at the probe itself. If that measurement is out of range, replacing the harness and receptacle is the first step. The probe should be tested separately before assuming it is the failed component.

Start by unplugging the oven and checking the resistance across pins 3 and 4 on connector J300 of the machine control board. With the probe installed, you should read 30k-50k ohms; with no probe, the circuit should read open. If the reading is outside these values, replace the meat probe harness and receptacle first, since these are the most common failure points. If resistance still does not meet specification after replacing those parts, test the probe itself and then consider the control board.

A replacement meat probe typically costs between $20 and $50, and a harness and receptacle assembly usually runs $30 to $80 depending on the model. If you are comfortable with basic multimeter testing and appliance disassembly, this is a manageable DIY repair. A machine control board, if that turns out to be the failed component, can cost $150 to $300 or more, making professional diagnosis worthwhile before purchasing one.
