Commercial Laundry Control Board Moisture and Corrosion Damage – Board Shorting or Burnt Smell | UpFix

Moisture Is the Silent Killer of Laundry Electronics

Commercial laundry rooms are hot, humid, and filled with detergent vapors. Over time, that environment slowly attacks every circuit board inside your washers and dryers.
Even a small amount of condensation or chemical residue can cause corrosion, short circuits, or burned components. Once it starts, performance drops, sensors misread, and eventually the machine shuts down completely.

Replacing every board each time this happens is expensive and unsustainable. That’s why professional repair—and prevention—matters.

Common Symptoms

  • Burnt smell from inside the control panel

  • Visible green or white corrosion on connectors or solder points

  • Machine turns on, then powers off immediately

  • Error codes like “Voltage Fault,” “Power Error,” or “No Comm”

  • Intermittent operation that worsens over time

  • Relays clicking but nothing happening

These symptoms affect all major commercial brands including Speed Queen, Dexter, Huebsch, Maytag, Unimac, Continental Girbau, ADC, and Electrolux.

Typical Fault Codes and Their Meaning

Code Description Likely Cause
E01 / E10 Voltage error or reset Moisture shorting voltage regulator
E90 / COMM FAIL Lost communication Corroded signal trace or connector
E5 / HE1 Overheat or ignition error Residue bridging power lines
PF / E67 Power fault Rust or oxidation on relay contacts

If your machine smells burnt but nothing is visibly damaged, corrosion under the protective coating is often the hidden culprit.

Why Moisture Damage Happens

  1. High humidity from constant heat and steam in laundromats.

  2. Detergent residue acting as a conductive film across components.

  3. Condensation forming on boards after night-time cool-downs.

  4. Leaking gaskets or vents allowing mist inside cabinets.

  5. Improper ventilation causing heat and moisture buildup.

Reddit technicians often say: “Looks fine until you pull the board out—then you see the green crust all over the solder joints.” That “green crust” is copper oxidation eating through your board.

Why Repair Beats Replacement

Replacing a corroded board might seem easy, but without addressing the underlying issue, new ones fail just as quickly. OEM replacements run $500–$1,000+ and often come without environmental sealing.

UpFix repairs and reconditions your original board, removing all corrosion, rebuilding affected traces, and adding protective coating to prevent future damage. You get a board that’s stronger than new—and save hundreds in the process.

How UpFix Repairs Moisture & Corrosion Damage

  1. Detailed inspection under microscope to locate all corrosion points.

  2. Chemical cleaning using specialized solvent baths.

  3. Ultrasonic rinse and drying process to remove residue.

  4. Trace and component repair for any burnt or oxidized circuits.

  5. Protective conformal coating for long-term humidity protection.

  6. Full bench testing under simulated heat and load conditions.

Each board is returned clean, sealed, and tested—ready to plug back in and last.

Real-World Example

A laundromat in Georgia experienced random shutdowns on six washers during humid summer months. All control boards showed slight green corrosion near the power regulators. UpFix chemically cleaned, repaired traces, and re-sealed each unit with protective coating. The machines ran flawlessly afterward and remained stable through the next rainy season—saving the owner nearly $4,000 compared to new replacements.
