888-979-9343Delta VFD Drive Repair for Commercial Laundry & Industrial Applications | UpFix
When Your VFD Fails, Everything Stops
Whether it’s a commercial washer that won’t spin or an industrial blower that won’t start, a failed Variable Frequency Drive (VFD) brings everything to a halt.
These drives regulate motor speed, torque, and power delivery—but when they fault out, your machine’s productivity (and profitability) drops to zero.
UpFix specializes in Delta VFD repair for commercial laundry and industrial systems. We restore your original drive to factory condition at the component level—faster, cheaper, and greener than replacement.
Common Delta VFD Models We Repair
-
Delta VFD-M Series
-
Delta VFD-E Series
-
Delta VFD-B Series
We also service other brands used in commercial and industrial systems: Lenze, Invertek, ABB, Yaskawa, Danfoss, LG, and Schneider.
Typical Fault Codes and What They Mean
| Fault Code | Description | Common Cause |
|---|---|---|
| OC1 / OC2 | Overcurrent Trip | Shorted IGBT or jammed motor load |
| OV | Overvoltage | Power spike or weak DC bus capacitors |
| LV | Low Voltage | Input power drop or regulator failure |
| EF / EEPROM Error | Data corruption or logic fault | Failed microcontroller or memory IC |
| E2 | Overtemperature Fault | Cooling fan or thermal sensor failure |
| No Motor Response | Drive powers on but motor doesn’t run | Faulty driver IC or signal relay |
| Erratic RPM / Speed Instability | Motor surging or losing torque | Damaged current feedback circuit |
If your washer, dryer, or machine shows these faults, the drive itself—not the motor—is usually the issue.
Why Delta VFDs Fail
-
Overcurrent or overload events during start-up or jammed pumps.
-
Voltage surges from unstable power supply.
-
Cooling fan failure causing thermal shutdown.
-
Aging capacitors leading to ripple voltage spikes.
-
Moisture or corrosion inside the cabinet.
Once an IGBT or driver circuit fails, replacing the drive can cost up to $1,500—but repair restores full function for a fraction of that.
How UpFix Repairs Delta VFD Drives
-
Comprehensive diagnostic scan of all power and logic stages.
-
Replacement of shorted IGBT modules, power MOSFETs, and capacitors.
-
EEPROM recovery to preserve factory configuration and firmware.
-
Cooling fan and temperature sensor replacement.
-
Ultrasonic cleaning to remove dust, lint, or corrosion buildup.
-
Bench load testing under simulated motor operation to verify torque stability and frequency output.
We return every drive fully tested, reconditioned, and plug-and-play ready—with all original settings preserved.

Real-World Example
A laundry operator in Chicago reported six Speed Queen washers showing OC1 and OV faults. The OEM quoted $1,200 each for replacement drives.
UpFix diagnosed multiple shorted IGBTs and failing capacitors, repaired all six Delta VFD-M drives, and had them back in service within three days—saving the operator over $5,000 and weeks of downtime.
