Common Causes
- 1Freezer thermistor failure

Step-by-Step Troubleshooting

- 2
Disconnect and measure resistance: approximately 16,000 ohms at 32F (0C)

Pro Diagnostic Tip
An open freezer thermistor causes the control board to lose temperature feedback. On Maytag models, this typically results in the compressor running continuously (the board defaults to maximum cooling when it loses the sensor signal), leading to frost buildup on the evaporator.
