A water heater that won’t heat usually has one failed part, but the symptom doesn’t tell you which. No hot water can be a thermocouple, a gas control valve, a venting fault or a burner problem. David tests the heater first, then supplies and installs the part that actually failed, matched to your model.
Service call $169 (call-out and diagnosis, parts extra). Monday to Saturday, 9 AM to 9 PM.
Tank Water Heater Parts That Fail Most Often
- Thermocouple or thermopile: proves the pilot is lit. When it weakens, the pilot won’t stay on.
- Gas control valve: controls gas to the pilot and burner and holds the thermostat. Test before replacing; it is the most expensive part.
- Temperature and pressure relief valve: a safety valve that can wear and drip.
- Anode rod: protects the tank from corrosion and wears away over time.
- Dip tube: sends cold water to the bottom. A broken one makes hot water run out fast.
- Drain valve: can leak or seize, especially on older tanks.
- Power-vent motor: on power-vented tanks, a failed fan stops the burner.
Tankless Water Heater Parts
- Igniter and flame sensor
- Flow sensor
- Combustion fan
- Control board and error-code diagnosis
- Heat exchanger, which usually means replacement if it fails
What to Send Us
A photo of the rating label (brand, model and serial number) and any error code. That lets David check part availability before the visit.
