Frequently Asked Questions

What does error code F6 mean on an Amana refrigerator?
Error code F6 indicates a fault with the evaporator thermistor sensor. This sensor is located in the freezer and monitors coil temperature for proper defrost cycling.
Can I still use my refrigerator with the F6 error?
The fridge may still run, but cooling efficiency will be affected, and defrost cycles may not work correctly, leading to frost buildup. It's best to fix it promptly.
Where can I buy a replacement evaporator thermistor for my Amana refrigerator?
You can purchase the thermistor from appliance parts stores, online retailers like Amazon, or directly from Amana. Look for a generic evaporator thermistor compatible with your model.
How do I test the evaporator thermistor on my Amana refrigerator?
Use a multimeter set to ohms. Disconnect the thermistor and measure its resistance. At room temperature, it should be around 50k ohms. Compare to your model's spec. If open or shorted, replace it.
Can I bypass the evaporator thermistor to clear error F6?
Bypassing the thermistor is not recommended as it will disrupt the defrost cycle and can cause cooling issues or damage. Always replace a faulty thermistor.
