What to do when Your Commercial Ice Maker not Making Ice

Commercial ice makers are a critical part of any food-related business. Even when it’s cold outside, people still want ice in their drinks. A problem with your ice will end up being a problem for your reputation. We’ve put together the most common commercial ice maker problems and how to solve them.

You may be able to diagnose and repair a faulty ice maker yourself before forking over cash for an expensive service call. Here’s how to fix commercial ice makers not making ice problems.

Like any other appliances, your commercial ice makers may not turn out the ice you need as they may also experience some trouble. So you need to troubleshoot the following and find out if these problems exist to be able to restore back your ice maker in good order.

Check the Shutoff Arm

The commercial ice maker has an arm extending away over the ice cube bin. This arm raises up and drops down after a block of ice is placed into the ice cubes bin during each ice-making cycle. If the ice accumulates in the bin, the arm is prevented from dropping back down. As the arm rises high enough, the ice maker will shut off so that no ice can be made until the ice in the bin lowers down.

You can manually turn off the ice made by lifting the arm until it reaches a locked position. At one or both ends, this arm is supported. One of the ends may extend into the back of the front support, which means it is not securely in place and could result in malfunction. So you need to check if the arm is securely in place.

To ensure proper operation, check if the arm is in the lowered position so that nothing hinders it from its normal movement. Also, test the shutoff function by lifting the arm into the manual shutoff function. If the unit goes on making ice even if the shutoff arm is in the off position, you may refer to the diagnostic table and replace the control module.

Check the Supply Valve

The ice maker has a water supply line that connects to a supply valve usually located under the kitchen sink or at the back of the freezer. Once this valve is not turned on to a position allowing enough pressure, water may not fill the ice mold, so the water valve located behind the freezer should be plumbed.

A timing mechanism is used to fill the ice mold. When water flows in too slowly, the ice mold will not be full until the time mechanism completes the cycle resulting in small ice cubes.

So, check the water valve if it is opened properly to allow enough water into the ice mold. The valve can be fully opened, but it is better to open it just enough to have an adequate pressure level. Inspect also the water supply line for dents or pinching as it might obstruct the flow of water to the ice maker.

Inspect the Water Supply Line

Often, the supply line runs from the water source to a valve plumbed in behind the freezer. Damage along this line may result in the hindrance of water flow to the ice maker resulting in small cubes or no ice at all.

Notice if there is water outside the freezer, which can be caused by a leak in the supply line. You can locate this leak by finding the water supply line behind the freezer, usually made up of copper or plastic connected to the water inlet valve.

From this inlet valve, follow this tubing to the water source. The leak can be fixed with the replacement of this water supply line. You need, however, to unplug the unit first to prevent electrical shock hazards before disconnecting and replacing the supply line with a new one.

Test the OnOff Switch

An ice maker has two types. To know what kind of model you are working on repairs on, remove the outer faceplate. If there is a knob, pull it off before prying the faceplate with a screwdriver. Be Cautious and Don’t test the shutoff switch unless the freeze or refrigerator is not in use so as not to expose yourself to possible electrical shock hazards.

The modular units of ice makers have holes in the modular face plate utilized for test probes. The holes are marked with letters. The other type of ice maker showcases component units that have gears and do not have holes for test probes.

Check The Freezer Temperature

The temperature level for the freezer is ideally five-degree Fahrenheit. But the refrigerator should be kept at thirty-six degrees Fahrenheit. To keep these temperatures at their ideal levels, they can be adjusted through the controls inside the freezer.

The freezer temperature cannot be measured by the thermostat inside. Proper measurement can be ascertained by placing a cup of alcohol or cooking oil with a cooking thermostat into the freezer for about two hours. The oil will not freeze, making it possible to measure the temperature accurately.

If you have already exhausted the following measures, you need to inspect and examine the ejector gear. There is a chance that the ejector gear is already worn out, which makes it difficult to create ice. Apart from the ejector motor, you should also test the ice mold heater, the holding switch, and the inlet switch.

Safety Tips

Before following the steps mentioned in this troubleshooting guide, make sure that you read the safety information provided to you by the product’s manufacturer. You need to be careful and be aware of the safety concerns when undertaking the steps mentioned above.

Read and understand the details included in the product manual as they can come in really handy. When testing the shutoff switch, unplug the machine. And if you are uncertain as to how you will do the repair, it is better to just leave it for the experts to do the job.
