Things to Keep in Mind Before Replacing Your Manitowoc Ice Machine Control Board

The control board of your Manitowoc Ice Machine is a crucial component that manages various functions, such as turning the machine on and off and dispensing ice. However, if the control board is faulty, it can lead to poor quality ice production and other issues. To ensure the smooth functioning of your ice maker, it’s important to keep a few things in mind before replacing the control board.


Firstly, it’s essential to identify whether the control board is actually the problem. One of the best ways to tell if a circuit board is damaged is to look for signs such as crushed components, bulges, cracked wires, extra solder, burn marks, and scratches. If you observe any of these signs, then it’s likely that the board needs to be either repaired or replaced. Scratches, in particular, can expose the connections beneath the lamination and cause further damage to the board.


However, before you order or replace the Manitowoc control board, there are a few probes that you should check. The water level probe can sometimes falsely report a full sump trough when it becomes dirty from scale build-up. This can lead to the board shutting off the water inlet valve, resulting in thin or no ice formation. Similarly, the ice thickness probe can also become dirty and cause the ice machine to report a full sheet of ice despite little to no ice formation. This can eventually result in a safety limit lockout from early harvests with no ice to trip the bin switch. It’s essential to clean or replace these probes before replacing the control board to avoid further issues.


Once you’ve identified that the control board needs to be replaced, it’s important to check your ice machine’s warranty before proceeding. If your machine is still under warranty, you may not need to order a new control board.
