Maytag Refrigerator Deli Drawer Temperature Control... | appliancefaults.com

Technical Background:

The Maytag refrigerator uses a temperature control slider to regulate the amount of cold air entering the deli drawer. The slider typically connects to a mechanical or electronic air damper. The main control unit (MCU) reads the thermistor value in the deli drawer and adjusts the damper. The MCU also controls the compressor and fans based on temperature readings from various thermistors.

Symptoms:

US homeowners report that the deli drawer temperature control slider on their Maytag refrigerator is broken or not functioning. The deli drawer may be too warm or too cold, regardless of the slider position.

Possible Causes:

Broken temperature control slider handle or mechanism.
Dislodged or damaged linkage between slider and air damper.
Faulty air damper preventing proper temperature regulation.
Icing or obstruction within the deli drawer vent or air pathway.
Defective thermistor sensing deli drawer temperature.

Solution:

1

Disconnect power to the refrigerator by unplugging it from the outlet or switching off the breaker at the breaker panel.
2

Carefully remove the deli drawer from the refrigerator.
3

Inspect the temperature control slider for visible damage, such as cracks or breaks. Replace the slider if damaged. Replacement sliders can be found online or at local appliance parts stores.
4

Examine the linkage between the slider and the air damper. Ensure it is properly connected and not obstructed. Clean any debris or ice buildup with a soft cloth.
5

Test the air damper functionality. With the refrigerator powered back on, move the temperature control slider and observe the damper opening and closing. If the damper does not move, it may be faulty and require replacement. A multimeter can test for continuity of the damper motor windings.
6

If the damper appears functional, check for any obstructions within the deli drawer vent or air pathway. Remove any items blocking airflow.
7

Reassemble the deli drawer and test the temperature control functionality. Allow the refrigerator to run for several hours to ensure proper temperature regulation in the deli drawer. Measure the temperature with a thermometer, it should be around 38-40 degrees Fahrenheit.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. Electrical components carry 120V AC and can cause serious injury or death. Follow Lock Out/Tag Out (LOTO) procedures to ensure the refrigerator remains de-energized during the repair.

Prevention:

Regularly clean the refrigerator interior, including the deli drawer area. Avoid overpacking the deli drawer, which can restrict airflow. Inspect the temperature control slider and linkage periodically for signs of wear or damage.

Expert Tip:

Many Maytag refrigerators have a service mode that allows you to test the air damper and other components. Refer to the refrigerator's service manual for instructions on entering service mode. Activating service mode usually involves pressing a sequence of buttons on the control panel.

Frequently Asked Questions

•How do I access the air damper to inspect it for damage?

The air damper is typically located behind the deli drawer, often concealed by a rear panel. Remove the deli drawer and any associated shelving or components to access the panel. The panel may be secured with screws or clips. Once the panel is removed, you should be able to see the air damper.

•What is the correct part number for the deli drawer temperature control slider for my Maytag refrigerator model?

To determine the correct part number, locate the model number of your refrigerator. It is typically found on a sticker inside the refrigerator compartment or on the back of the unit. Once you have the model number, you can search online appliance parts retailers or contact a local appliance parts store. Providing the model number ensures you receive the correct replacement part.

•How do I test the thermistor in the deli drawer to see if it is working correctly?

A thermistor's resistance changes with temperature. Disconnect the thermistor from the main control board. Use a multimeter set to ohms to measure the resistance. Then, compare the resistance value to a thermistor resistance chart (usually available in the service manual for your refrigerator model) at a known temperature (e.g., room temperature). If the measured resistance deviates significantly from the chart value, the thermistor may be defective.
