About Tankless Water Heater Control Board Replacement

The printed circuit board (PCB) is the central brain of your tankless water heater, controlling ignition sequences, gas modulation, fan speeds, safety loops, and digital communications. In Alsip, Illinois, electrical power surges, lightning strikes, or internal water leaks can burn out capacitors, fry microcontrollers, or corrupt system memory. Our technicians diagnose board-level failures, verify transformer voltages, and replace fried motherboards with factory-programmed OEM control boards, configuring DIP switches for your exact setup.

What Our Customers Say

Real reviews from property owners we've helped across our service areas.

Our Navien NPE-240A started throwing error code E003 on a freezing Tuesday morning. The technician arrived in 35 minutes, tested the gas line pressure, and found our flame sensor was heavily coated in carbon. He cleaned the rod, checked the burner combustion, and had boiling hot water running again in less than an hour. Straightforward pricing and zero runaround.

We had terrible cold water sandwiching where the shower would turn freezing cold for 15 seconds in the middle of washing. TWH PRO's diagnosed our failing thermal bypass valve and calibrated our internal recirculation pump. The shower is completely steady now. Excellent technical trade knowledge.

Our restaurant's cascaded 3-unit commercial Rinnai system had one unit completely locked out with Code 11 right before our Friday evening dinner service. They dispatched a technician immediately who replaced the ignition electrode pack from his truck inventory. Saved our kitchen from shutting down.
