Gas Tankless Water Heater Repair in Merced
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve failures to carbon monoxide sensor errors. Our licensed technicians in Merced perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
No Hot Water Tankless Repair in Merced
When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger. Our technicians in Merced will thoroughly diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction or mineral buildup. We carry common replacement parts for quick fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is essential for the safe operation of your unit.
Ignition Failure Repair in Merced, CA
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 common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Tankless Descaling and Flushing in Merced
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 wise for most homes on hard water.
Navien Tankless Water Heater Repair in Merced
Navien units are known for their advanced condensing technology but can sometimes develop issues with their circulation pump or exhaust systems. FBL Plumbing provides specialized Navien tankless water heater repair in Merced, addressing common problems like ignition failures or condensate drain blockages. Our team is familiar with Navien's parts and troubleshooting protocols, delivering a precise and effective repair that maintains your unit's high efficiency.
Flow Sensor and Thermistor Repair in Merced
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 faulty parts. Temperature becomes steady again once readings are correct.

Yes, regular maintenance, particularly annual descaling where water is hard, is crucial for tankless water heaters. It prevents mineral buildup, maintains efficiency and extends the lifespan of the unit, often heading off costly repairs.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
