11 Common Causes of Frigidaire Ice Maker Malfunctions

Is your Frigidaire refrigerator failing to churn out ice as it once did, even though the water dispenser is still in working order, or perhaps delivering water at a frustratingly slow pace? Fret not; you’re not alone in facing this common issue. In this comprehensive guide, we’ll explore eleven prevalent culprits behind the “Frigidaire Ice Maker Not Working” problem and delve into practical solutions to get your ice maker back in action.

Ice Maker Switch Turned Off

One of the most straightforward reasons behind a malfunctioning ice maker is a switched-off ice maker switch, often inadvertently toggled into the off position. This can disrupt ice production entirely. First, confirm that the switch is set to the “on” position to diagnose this issue. If it’s already on, yet the ice maker remains inactive, employing an Ohm meter to test its continuity becomes essential.

If the switch fails this continuity test, it’s advisable to replace it promptly. This simple troubleshooting step can quickly resolve the problem and restore your ice maker’s functionality, ensuring a steady supply of ice for your needs.

Freezer Temperature Above 10 Degrees F (-12 C)

The temperature within your freezer is a critical factor affecting the performance of your ice maker. If the freezer temperature rises above 10 degrees Fahrenheit (-12 degrees Celsius), your ice maker will likely encounter difficulties in its operation. It functions best when temperatures are between 0 and 5 degrees Fahrenheit (-18 to -15 degrees Celsius). To address this issue, begin by inspecting the cleanliness of the condenser coil, which plays a vital role in heat exchange. Ensure that the condenser fan is efficiently cooling both the condenser and compressor, as proper cooling is essential for maintaining the desired low freezer temperature.

Additionally, be vigilant for excessive frost buildup on the evaporator coil, as it can impede airflow. If frost accumulation is significant, it may disrupt air circulation, ultimately affecting ice production. In such cases, thoroughly examining the defrost components is necessary to identify and rectify any potential failures, allowing your ice maker to function optimally once again.

Faulty Door Seal

Inconsistent temperatures can also result from a faulty door seal. A compromised seal allows warm air to infiltrate the fresh food compartment, triggering the temperature sensor to engage the compressor excessively to maintain a 37-degree Fahrenheit. This overcooling can freeze the water tube, impeding the water supply to the ice maker. To rectify this, ensure self-closing doors and adjust leveling rollers or legs for proper sealing. With a tight seal, defrost cycles will clear the water tube, initiating ice production within 24 hours.

Clogged Water Filter

If your refrigerator’s ice maker remains non-operational despite troubleshooting, it could be attributed to a clogged water filter. This obstruction hinders the free flow of water necessary for ice production. To resolve this issue, it is advisable to replace the water filter. By doing so, you can ensure that water flows unimpeded, potentially resolving the problem and allowing your ice maker to resume its normal functioning, providing a consistent supply of ice for your cooling needs.

Low Water Pressure

More water pressure within your home can pose a significant obstacle to the optimal functioning of your ice maker. The water inlet valve, responsible for delivering water to the ice maker, necessitates a minimum water pressure of 20 pounds per square inch (psi) to operate effectively. When water pressure falls below this threshold, it can impede the valve’s ability to supply adequate water to the ice maker, potentially leading to a reduction in ice production or even complete inactivity. Addressing low water pressure issues ensures your ice maker works as intended.

Faulty Door Switch

The door switch in your refrigerator has a dual role, serving as the trigger for the freezer’s light and as a safety mechanism to deactivate the ice maker and dispenser when you open the freezer door. A malfunctioning door switch can disrupt the operation of these features. You can use an Ohm meter to test the switch’s continuity to diagnose this issue. If the switch fails this continuity test, it’s not effectively completing the electrical circuit when the door is closed. Replacing the defective door switch is essential to ensure the proper ice maker and dispenser functioning when needed.

Faulty Water Inlet Valve

If your freezer’s temperature is suitable, but the ice maker remains dormant, consider the water inlet valve the culprit. This electrically controlled mechanical valve, responsible for supplying water to the dispenser and ice maker, might be malfunctioning or experiencing insufficient pressure. A minimum of 20 psi is required for the valve to operate optimally. Confirm that the water pressure meets this threshold and use a multimeter to test for power to the water inlet valve. If the pressure is sufficient and power reaches the valve, the ice maker fails to fill with water, and replacing the water inlet valve is warranted.

Faulty Ice Maker Assembly

Occasionally, the source of ice maker troubles can be traced back to the ice maker assembly as a whole. This assembly encompasses various components within the control module; many of these parts are not sold separately for replacement. Due to the relatively limited lifespan of ice makers and the potential complexity of diagnosing and fixing individual components within the assembly, replacing the entire ice maker assembly is often more cost-effective than attempting intricate repairs.

This approach saves time and ensures a comprehensive solution to any underlying issues. It’s a practical choice, particularly when other potential problems have been thoroughly investigated and eliminated, providing a fresh start for your ice maker and a dependable source of ice for your needs.

1. Remove the ice maker and its control head unit.

2. Locate the thermostat pins on the unit’s backside.

3. To assess the thermostat’s functionality, employ a multimeter to check for continuity. At room temperature, the reading should be 0Ω.

4. After leaving the thermostat in the freezer for several hours and retesting, it should register either OL (open loop) or a value between 16 degrees Fahrenheit (-9 degrees Celsius) and -4 degrees Fahrenheit (-20 degrees Celsius).

5. If the thermostat behaves differently, it necessitates replacement.

Ice Level Control Board

If your ice maker remains unresponsive and uncooperative, the issue may lie with the ice level control board. This crucial component operates using an ingenious system. Your refrigerator utilizes an infrared light beam to gauge the ice level within the ice bucket. When the ice reaches the top and interrupts this beam, a signal is sent to the ice maker, prompting it to pause its operations.

As you use ice and the ice level decreases below the beam’s line of sight, the ice maker is triggered to resume ice production. However, if the ice level control board experiences a malfunction or failure, it disrupts this delicate balance. In such cases, the ice maker may either stop making ice entirely or continue producing ice even when the bucket is full. Ensuring the proper functioning of this control board is pivotal to maintaining a reliable and efficient ice maker.

Ice Maker Mold Thermostat

The ice-maker mold thermostat within the control module plays a pivotal role in the ice-making process. This thermostat diligently monitors the temperature of the ice mold or tray. The ice maker triggers a harvest cycle when the mold reaches the correct temperature, signifying that the ice is frozen and ready. During this cycle, it ejects the ice cubes and refills the mold with water to initiate a fresh ice-making cycle. However, if this thermostat experiences a malfunction, it disrupts the entire sequence, causing the ice maker to stall.

You can test the thermostat’s continuity using a multimeter to diagnose this issue. If it fails this test, replacing it becomes imperative to restore the ice maker’s functionality. Maintaining your freezer temperature within the optimal range of 0-5 degrees Fahrenheit (-18 to -15 degrees Celsius) is crucial to ensure efficient performance, as this thermostat relies on a specific temperature threshold to operate effectively.


When grappling with the frustrating “Frigidaire Ice Maker Not Working” problem, a systematic approach to troubleshooting is crucial.
