Flow Sensor and Thermistor Repair in Pahrump
Tankless heaters rely on flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace failed parts. Temperature becomes steady again once readings are correct.

Pilot Light & Ignition Repair in Pahrump, NV
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Pahrump, NV diagnoses issues with igniters, flame sensors and gas valves. We confirm proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents hazardous gas problems and restores your unit's ability to heat water on demand.
Emergency Tankless Repair in Pahrump
A tankless unit that leaks internally or shows a fault you cannot clear needs prompt attention. We put first no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meanwhile.
Condensing Tankless Repair in Pahrump, NV
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and confirm proper drainage. PVC venting is also inspected for slope and sagging.
Tankless Descaling and Flushing in Pahrump
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is a smart move for most homes on hard water.
Ignition Failure Repair in Pahrump, NV
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.
Navien Tankless Water Heater Repair in Pahrump
Navien units are known for their advanced condensing technology but can sometimes experience issues with their circulation pump or exhaust systems. FMR Plumbing provides dedicated Navien tankless water heater repair in Pahrump, addressing common problems like ignition failures or condensate drain blockages.
