What 00 means on a Amana dryer

Error code 00 on an Amana dryer appears during the temperature regulating circuitry diagnostic routine and indicates that the thermistor is reading approximately 100°F. This is a display code, not necessarily a fault, meaning the control board is reporting a sensor reading rather than signaling a confirmed component failure. The thermistor is a temperature-sensitive resistor that feeds real-time temperature data to the control board, allowing it to regulate heating cycles accurately. If the displayed reading deviates more than 10°F from an independent temperature probe measurement taken at the same location, the thermistor or its wiring circuit warrants inspection.

For homeowners, this code is the dryer's way of showing you what temperature the thermistor is currently detecting inside the machine during a diagnostic check. Think of it as a readout rather than an alarm. If your dryer is behaving normally and drying clothes efficiently, this reading may simply reflect ambient or residual heat. However, if drying performance is poor or the code appears alongside erratic heating, the thermistor sensor or the wiring connecting it to the control board may be giving inaccurate readings.

The 10°F threshold matters because thermistors naturally have a small tolerance range, but anything beyond that suggests a calibration problem, a damaged sensor, or a wiring issue affecting the signal reaching the control board.

Common causes of 00

  1. 01

    Inaccurate thermistor reading due to sensor drift or damage

    Part replacement

    The thermistor itself may have drifted out of its accurate resistance range or sustained physical damage, causing it to report a temperature that does not match actual conditions. This results in a more than 10°F discrepancy when compared against an independent probe reading.

  2. 02

    Loose, corroded, or damaged wiring to the thermistor

    Wiring / connection

    A poor electrical connection in the wiring harness between the thermistor and the control board can introduce resistance or signal noise, causing the displayed temperature to read incorrectly. Inspecting connector pins and wire insulation at the thermistor harness is a necessary step before replacing the sensor.

  3. 03

    Thermistor positioned incorrectly or dislodged from mounting location

    Wiring / connection

    If the thermistor has shifted away from its designed position, it will read ambient air temperature rather than the air stream it is intended to monitor, producing a reading that appears low or inconsistent with actual drum temperatures.

  4. 04

    Control board not processing thermistor signal accurately

    Part replacement

    In less common cases, the control board's input circuit for the thermistor signal may be faulty, causing it to display an incorrect temperature even when the thermistor and wiring test within spec. This is typically diagnosed after the thermistor and wiring have been confirmed good.

Frequently asked questions about 00

What does error code 00 mean on an Amana dryer?
Code 00 is a temperature display code that appears during the dryer's diagnostic routine for the temperature regulating circuitry. It shows the temperature the thermistor is currently reading, which should be approximately 100°F during this test. It is a reporting code, not automatically a fault, but a discrepancy of more than 10°F compared to an independent probe measurement indicates a thermistor or wiring problem.
How do I fix error code 00 on my Amana dryer?
Start by using an independent temperature probe to compare its reading against the 100°F value shown by code 00. If the difference is more than 10°F, inspect the thermistor wiring harness for loose pins, corrosion, or damaged insulation. If wiring checks out, test the thermistor's resistance against the manufacturer's specification for the measured temperature and replace the thermistor if it falls outside range. If both the thermistor and wiring test good, the control board's input circuit may be at fault.
Is it safe to use my Amana dryer when code 00 is showing?
Code 00 appearing during a diagnostic routine does not necessarily mean the dryer is unsafe to run, but it does indicate you should verify the thermistor reading accuracy before relying on the dryer for normal use. If the thermistor is reading significantly off, the control board may not regulate heat correctly, which could result in overheating or insufficient drying. Confirm the reading is within 10°F of an independent probe before continuing regular use.
How much does it cost to fix error code 00 on an Amana dryer?
If the fix is a loose wire connection, cost is minimal and the repair is DIY-friendly. A replacement dryer thermistor typically costs between $15 and $40 for the part. If a technician is needed, expect a service call fee of $75 to $150 plus labor, bringing the total to roughly $100 to $200 depending on your area. A control board replacement, which is the least likely cause, can run $150 to $300 for the part alone.
Can I check the thermistor on my Amana dryer myself when code 00 appears?
Yes, thermistor testing is a manageable DIY task with a multimeter. With the dryer unplugged, locate the thermistor, disconnect it from the wiring harness, and measure its resistance. Compare the reading to the resistance-temperature chart in the service manual for your specific model. A thermistor reading far outside the expected value at a known temperature confirms it needs replacement. If resistance is in range, move to inspecting the connector and wiring harness before suspecting the control board.
