About Tankless Water Heater Igniter Replacement

Every time you open a hot water faucet in Harwood Heights, Illinois, the igniter must generate an intense high-voltage electric arc or glowing ceramic heat within a split second. Operating in high-temperature combustion environments eventually erodes electrode tips and weakens high-voltage ignition transformers. When the igniter fails to spark, the unit clicks repeatedly and locks out on ignition failure. Our technicians measure transformer spark gap clearances, test coil secondary resistance, and replace eroded electrodes. We restore instantaneous, dependable ignition so hot water starts flowing the moment you turn the handle.

Common Problems We Solve With Tankless Water Heater Igniter Replacement

Rapid Clicking Without Fire

The electronic spark generator clicks repeatedly but no gas flame catches in Harwood Heights, Illinois.

Eroded Spark Gap Distance

The metal gap between electrodes widens past factory tolerances from spark erosion.

Faulty Ignition Transformer

Internal pulse transformer fails to produce high-voltage electrical discharge.

Tankless Water Heater Igniter Replacement Questions

Why is my tankless water heater clicking but not lighting in Harwood Heights, Illinois?

The igniter is trying to spark, but either the electrode gap is worn, the transformer is weak, or gas is missing. Call (888) 905-6092 to diagnose in Harwood Heights, Illinois.

How long do tankless igniters usually last?

Most tankless igniter electrodes last 5 to 8 years depending on cycle frequency. Call (888) 905-6092 for quick replacement.

Is a clicking igniter dangerous?

What Our Customers Say

Real reviews from property owners we have helped restore to endless hot water.

Our Navien unit flashed error E003 on a cold morning and stopped heating completely. The technician arrived with the exact OEM flame sensor rod on his truck, tested the gas manifold pressure, and had hot water flowing again within an hour. The diagnostic explanation was clear and pricing was fair.

Our Rheem tankless system kept shutting down during showers with code 12. Two other plumbers told us we needed a new unit, but this team discovered a clogged condensate trap and an oxidized flame sensor. They cleaned the burner assembly and saved us thousands compared to a premature replacement.

Hard water scale choked our Rinnai heat exchanger to the point where shower pressure dropped to a trickle. Their technician hooked up a high-volume descaling pump and circulated food-grade solution for over an hour. The difference in water pressure and heating speed was immediate.
