Commercial Dryer Ignition or Heat Control Board Failure – No Heat or Ignition Lockout | UpFix

When the Heat Goes Out, So Does Your Income

Nothing hurts a laundromat’s reputation faster than cold dryers.
Customers don’t wait—they just leave. And while burned-out ignitors or thermostats get blamed first, the true culprit behind most “no heat” calls is the ignition or heat control board. This board regulates voltage to gas valves, sensors, and ignitors to maintain safe, consistent heat.

When it fails, the dryer tumbles endlessly with cold air, or worse—locks out completely with a fault code. That’s lost income on one of your highest-earning machines.

Common Symptoms

  • Dryer tumbles but produces no heat

  • Ignitor glows briefly, then shuts off

  • “IGNITION FAULT” or “HEAT ERROR” on display

  • Dryer repeatedly cycles on and off without heating

  • Machine locks out after multiple failed ignitions

  • Burning smell or melted marks on board connectors

These problems are most common in Speed Queen, Huebsch, Maytag, Dexter, ADC, Unimac, and Continental Girbau commercial dryers.

Typical Fault Codes and Their Meaning

Code Description Likely Cause
E5 / HE1 Ignition failure Faulty ignition relay or weak voltage driver
E7 / HE2 Overheat shutdown Thermistor or feedback circuit fault
E3 / HF Flame sensor error Signal path or ground circuit failure
E9 / HC Heat control communication fault Logic board error

If fuses, ignitors, and thermostats test fine but the dryer still won’t heat, the ignition control board is almost always the problem.

Why Heat Control Boards Fail

  1. Constant high voltage and amperage stress components over time.

  2. Moisture and lint dust create conductive film on the PCB.

  3. Thermal cycling expands and cracks solder joints.

  4. Voltage spikes damage relays and power regulators.

  5. Aging capacitors lose filtering ability, causing voltage drift.

Many operators report “burnt smell near the back of dryer” — a telltale sign that the board’s power regulator or relay has failed.

Why Repair Is Smarter Than Replacement

New ignition or heat control boards cost $400–$900, and some older models are discontinued entirely. Dealers often require full assembly swaps, which drives up costs even more.

UpFix repairs your existing board for a fraction of the cost. Your unit is restored at the component level — no reprogramming, no compatibility issues, and no rewiring needed.

How UpFix Repairs Heat Control Boards

  1. Comprehensive testing of ignition, sensor, and valve output circuits.

  2. Replacement of failed relays, resistors, and voltage regulators.

  3. Reflow and reinforcement of heat-stressed solder joints.

  4. Cleaning and protective coating against lint and moisture intrusion.

  5. Bench simulation testing of ignition and temperature control cycles.

Each board is verified through multiple on/off heating cycles under simulated dryer loads to ensure perfect performance before shipping back.

Real-World Example

A Dexter T-50 dryer was tumbling fine but never produced heat. The owner replaced ignitors twice before sending the control board to UpFix. We discovered a burnt relay coil and cracked solder joint under the ignition driver. After repair and reconditioning, the board passed all heat-cycle tests and was reinstalled within two days. The machine was back in service earning money that same weekend.
