Commercial Washer or Dryer Power Supply / Relay Board Failure – Machine Randomly Shuts Off or Loses Power | UpFix

When Machines Lose Power, Your Profits Go Dark

Few problems in a laundromat feel worse than watching a washer shut off mid-cycle or a dryer die with a full load inside. It’s not just one machine down — it’s lost revenue, refunds, and frustrated customers.

The real cause behind many of these shutdowns isn’t the breaker or outlet — it’s a failing power supply or relay control board. This board regulates voltage and delivers power to motors, heaters, and electronics. When it malfunctions, your machine loses the heartbeat that keeps everything running.

Common Symptoms

• Washer or dryer turns off mid-cycle

• Display flickers or resets randomly

• Machine powers on but won’t start a cycle

• Clicking or buzzing sound near relay board

• Burnt smell or black dust around power section

• Error codes for “Voltage Fault” or “Power Loss”

These symptoms are especially common on Speed Queen, Dexter, Huebsch, Maytag, Unimac, Continental Girbau, and Electrolux machines.

Typical Fault Codes and Meanings

If the machine works intermittently or resets after a cycle, the internal power board is usually to blame.

Why Power Supply and Relay Boards Fail

1. Voltage spikes and brownouts from utility fluctuations.

2. High heat and vibration inside the machine cabinet.

3. Aging capacitors that can’t hold steady voltage.

4. Moisture and detergent vapors causing corrosion.

5. Relay fatigue from thousands of start-stop cycles.

Operators often report: “It powers up, clicks, and dies again.” That’s a relay coil or power driver breaking down under load — a classic electronic failure that’s fully repairable.

Why Repair Beats Replacement

OEM power boards cost $600 to $1,000+ and are frequently back-ordered. Meanwhile, your machine sits idle.
UpFix repairs your original board at the component level, preserving your existing settings and saving you hundreds per unit. No reprogramming, no rewiring — just plug it back in and get back to work.

How UpFix Repairs Power and Relay Boards

1. Comprehensive power-flow testing for AC/DC stability and relay timing.

2. Replacement of burnt regulators, MOSFETs, and driver transistors.

3. Rebuild of relay circuits using high-temperature solder and industrial-grade relays.

4. Cleaning and conformal coating to guard against future corrosion.

5. Load testing under simulated washer/dryer conditions to ensure steady operation.

Every board passes multiple power cycles and thermal tests before it leaves our lab.

Real-World Example

A large laundromat in Chicago reported four Huebsch dryers shutting off randomly mid-cycle. UpFix diagnosed blown relay drivers and heat-stressed solder points. After replacing components and re-coating the boards, all units ran flawlessly under load testing and were back in service within 48 hours—saving over $2,000 in parts and weeks of downtime.
