Error codeF1E6
ApplianceMicrowave
Quick answer
F1E6 on a JennAir built-in microwave: a possible microwave thermistor or sensor fault, or the wiring to it.
Model compatibility: JennAir reuses codes across series and model years, so F1E6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
JennAir lists a possible problem with the microwave thermistor or sensor, or the associated wiring.
What the code is saying
A JennAir built-in microwave displaying F1E6 is reporting that its thermistor or sensor, or the wiring running to it, might have a fault. The manufacturer frames this as a possibility rather than a confirmed failure, and the only owner step it offers is a power reset.
Reset, step by step
Turn off the breaker or breakers supplying the unit. Leave them off for one minute.
Turn them on again.
Spend a full minute watching the display for F1E6.
Use the microwave as normal to confirm it works.
A clear display and a working unit means nothing more is listed. When the code returns, JennAir’s page says a qualified technician may be needed.
The thermistor in plain terms
Generally, a thermistor is a small part whose electrical resistance changes as the temperature does, and the control reads that resistance to judge how hot something is. A nonsensical reading, or a broken connection to the part, makes the control raise a code instead of guessing. JennAir does not say which of those two applies.
Leave the casing alone
High voltage is present in a built-in microwave, so the casing stays closed. Sensor and wiring testing belongs to a technician.
Other JennAir microwave codes to read
F1E5: the inverter and magnetron tube, a different microwave-side code.
If F1E6 comes back after the reset, call (310) 622-9465 for JennAir microwave service in Los Angeles. Keep the model number nearby and mention the code and the breaker cycle. The microwave repair page has related information.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
