JennAir Built-In Microwave 3D31 / 3D32 / 3D41 / F3E4 Error Code

A hands-on first move

This entry covers 3D31, 3D32, 3D41 plus F3E4. Unlike most JennAir microwave groups, the opening instruction is physical. JennAir wants you to confirm the probe is pushed securely into its receptacle before you touch the breaker.

About the probe and its socket

A meat probe is the food thermometer lead that attaches to the microwave so cooking can run to a set temperature; its socket is the receptacle. JennAir mentions that the receptacle’s position can vary, and your owner’s manual is the place to look for where yours is. Press until it feels firmly seated.

Then a power reset

1. Switch off the microwave’s circuit breaker.
2. Allow one minute to pass.
3. Switch the breaker on.
4. Look at the display for a minute and see whether the code shows again.
5. Confirm the microwave operates.

All four codes, same advice

• 3D31: seat the probe, then reset
• 3D32: seat the probe, then reset
• 3D41: seat the probe, then reset
• F3E4: seat the probe, then reset

Code remains

No further cause is given by JennAir. With the probe seated, the reset finished and the code still present, service is the next step. Taking the cabinet apart to examine the receptacle yourself is not advised.

Other probe-related entries

• F3E3 points at the probe, its socket or the wiring behind it.
• F3E0 concerns an oven temperature sensor, a part apart from the probe.
