Amana Dryer Error Code 00

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.

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.

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.

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.

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.
