Amana Microwave Error Code F3T1: Meaning and Fix
Reading the microwave display
On a microwave the code replaces the clock on the display. Unplug the unit for a minute to see if it clears, and note the code before you do. Amana models often flash lights instead of printing text, so count the flashes.
Amana is a Whirlpool Corporation brand sold mostly through builder and value channels. Its entry-level washers, dryers and ranges use the simpler Whirlpool-family control boards, so the codes are short and often shown as flashing lights. The codes apply to model numbers such as ADB1200AWS, ADB2200AWS and NDE2330AYW; check the label on your unit to confirm yours.
What causes F3T1
- Sensor has drifted, opened or shorted out
- Control board is misreading the sensor signal
- Thermal fuse or high-limit device has tripped
- Sensor harness is loose, pinched or corroded at the connector
- Airflow restriction made the appliance run hotter than it should
How to fix it
- Cycle the power: unplug the microwave (or switch off its breaker) for one minute, restore power and test it briefly with a cup of water.
- Before opening any panel, switch off the breaker or unplug the appliance; this circuit can carry line voltage.
- Power the unit down and let it cool, then clear any vent, filter or airflow restriction before re-testing.
- Locate the sensor named in the code and check that it is seated, undamaged and connected.
- With the connector unplugged, measure the sensor resistance with a multimeter and compare it to the chart for the model; an open or shorted reading means the sensor is bad.
- Replace the sensor (or thermal fuse) if it fails the test, then run a short cycle to confirm the code stays away.
- Run a full short cycle or function again and confirm the code stays gone before putting the appliance back into normal use.

Questions
What does F3T1 mean on a Amana microwave?
It is a fault code from the Amana control. It indicates a problem with a temperature sensor. A power reset is the first thing to try.
Can I keep using the microwave while it shows F3T1?
You can try it after a power reset. If the code returns, the affected function may not run properly, so it is worth fixing soon before it causes a bigger failure.
Do I need a technician to clear F3T1?
Many owners can fix it themselves. Start with the reset and the inspection steps, and only call a technician if the part tests bad and you do not want to replace it.
