The wax motor on the Maytag Neptune Washing Machine (Model MAH3000AWW) is one of the most common parts to fail. The wax motor can be tested with a multimeter. Follow these simple steps to test the wax motor:
**The electrical supply should be disconnected from the washing machine before performing this test**
- Remove the wire harness from the wax motor terminals
- Position the multimeter probes on the two terminals of the wax motor
- It should have a resistance of approx. 1900 ohms at room temperature
If the wax motor is not reading the proper resistance then it is bad and should be replaced.
