About Spark Generator Replacement Service

The electronic spark generator is a step-up pulse transformer that converts low-voltage direct current into thousands of volts of high-frequency spark energy to ignite gas burners. In Cornwall, Pennsylvania, electrical voltage spikes, extreme cabinet heat, and repeated ignition cycles break down internal high-voltage coil windings. When the spark generator weakens or fails, it produces a feeble, intermittent spark or stops clicking entirely, leaving the unit in chronic ignition lockout. Our technicians test primary and secondary transformer voltages, check spark arc frequency, and install genuine OEM solid-state spark generator modules.

Common Problems We Solve With Spark Generator Replacement Service

No Spark Clicking on Startup

Unit turns on and commands gas but the igniter never clicks in Cornwall, Pennsylvania.

Weak Yellow Spark Arc

Weak spark jumps erratically and fails to ignite high-velocity gas.

Blown Spark Transformer

Internal coil windings burn out, failing electrical continuity tests.

Spark Generator Replacement Service Questions

Why does my tankless water heater not click when I turn on a faucet in Cornwall, Pennsylvania?

A failed spark generator module, blown PCB fuse, or jammed flow sensor prevents the spark sequence from firing. Call (888) 905-6092 for diagnostics.

Can a weak spark cause error code 11?

Yes, a weak spark that fails to ignite the gas within 3 seconds causes the control board to lock out on error code 11. Call (888) 905-6092 to test your spark.

Do you install genuine factory spark modules?

Yes, we exclusively install genuine OEM spark generators to ensure correct voltage and long-term durability. Call (888) 905-6092 to schedule repair.

What Our Customers Say

Real reviews from homeowners and business owners we have helped.

Our Navien NPE-240A started beeping error code E003 on a freezing Tuesday morning. Marcus from TWH PRO's arrived within 40 minutes, tested the gas manifold pressure, cleaned the flame rod, and replaced a worn spark igniter on the spot. Having hot water back before our kids woke up was huge.

We went three days with lukewarm showers because our electric EcoSmart 27 kept tripping breakers. The technician tested the continuity of all three heating elements and found two had burned out from mineral scale. He swapped in genuine OEM canisters and descaled the chambers. Steaming showers are back.

Our restaurant dishwasher tripped a sanitation temperature alarm during Friday dinner service. TWH PRO's sent a commercial technician immediately. He cleared a clogged air intake screen on our cascaded Rinnai rack and re-calibrated the water servo in under an hour, saving our dinner service.
