Whirlpool Microwave Error Code F3E3-0

The F3E3-0 code means the microwave has detected a failure in the meat probe's NTC thermistor, which is the internal temperature sensor built into the probe accessory. The control board monitors the thermistor's resistance to track food temperature, and when that resistance falls outside the expected range, it triggers this fault. The error will prevent the probe cooking function from operating until the issue is resolved.

The F3E3-0 fault is specific to the meat probe circuit and does not indicate a problem with the core microwave heating components. Standard microwave cooking functions should remain operational. However, any cooking mode that relies on the meat probe for temperature control should not be used until the probe is repaired or replaced, as the sensor cannot provide accurate readings.

If the meat probe accessory itself is the failed component, replacement probe parts typically range from around $20 to $60 depending on the specific model. If a service technician is needed to diagnose and perform the repair, expect to add labor costs on top of the part price, bringing the total repair estimate to roughly $80 to $180 or more depending on your location and service rates.

In many cases, yes. Start by inspecting the probe cable for visible damage and cleaning the probe connector port on the microwave to ensure good contact. If the probe itself has failed internally, replacing the meat probe accessory is a straightforward repair that does not require disassembling the microwave. Accessing the diagnostics mode to confirm the sensor is reading incorrectly before purchasing parts is a recommended first step.

A power reset by unplugging the microwave for a few minutes may temporarily clear the error code from the display, but the fault will return as soon as the probe circuit is evaluated again by the control board. Because the error is caused by a failed component rather than a software glitch, the underlying hardware issue must be resolved to permanently clear the code.
