Commercial ice machine control board with power, OK, and status indicator LEDs
Field note October 2026

Ice machine down in Midlothian.

A control board failure, a machine in alarm, and a reminder that ice machines and curious fingers are a bad combination. Here’s what we found, what we replaced, and what your staff should know.

The call

A business in Midlothian called us out for an ice machine that had stopped making ice entirely. The machine was sitting in an alarm state, and the people on site had already been troubleshooting what they could safely reach. Then someone reached where they shouldn’t—and got a good shock for it.

Nobody was seriously hurt, and we’re glad of that. But it’s worth saying plainly: an ice machine is water, 115-volt power, and sheet metal sharing a very small space. If a machine alarms, the safest move is always to power it down and call a technician—not to go poking around inside it.

What we found

The machine hadn’t been cleaned in a while, and it was starting to show—first in the amount of ice it made, then in the quality of that ice. Then the control board put the machine into an alarm state. While trying to reset it, someone pushed on the wiring, and the board arced against the frame.

A machine that goes too long between cleanings works harder than it should, and the first signs usually show up in the ice before anything else. When the board finally calls it in with an alarm, the machine is telling you it needs attention—not that someone should start exploring inside it.

The fix

We replaced the failed control board, gave the entire unit a thorough cleaning, and made some minor adjustments so the machine runs the way the manufacturer intended. Then we let it do what ice machines are supposed to do: make ice.

No drama, no upsell—the board was done, so the board got replaced, and everything else that was still good got cleaned and preserved. That’s how this should work every time.

The takeaway

Yes, some ice machine designs are clumsy to reset and frustrating to live with. Even so, calling a technician is always cheaper than a shock, an injury, or turning a one-part repair into a two-part repair. And staying on a regular cleaning schedule is the difference between a machine that quietly makes good ice for years and one that alarms mid-shift and needs a board.

If your ice machine alarms

  • 1. Power the machine off at its disconnect—don’t reach inside a machine that’s energized.
  • 2. Note what the machine was doing—alarm codes, noises, ice thin or absent—and tell us when you call.
  • 3. Leave the interior to a technician. Water and line voltage in the same cabinet is our problem to solve, not yours.
