What does sensor failure mean on my hot water heater?
Andrew Henderson What does sensor failure mean on my hot water heater?
A thermocouple or flame sensor is a device used to control gas flow in gas water heaters. Often a bad thermocouple is the reason why a water heater pilot does not ignite or a burner does not stay lit.
Where is the temperature sensor on a gas water heater?
The inlet and outlet temperature sensors work together to ensure the desired set temperature on the water heater is reached accurately. The cold water sensor is located in the water valve and the hot water sensor is clipped on the hot water outlet pipe.
How much does it cost to replace a gas valve on a water heater?
Most plumbers will charge between $100 and $200 to replace the gas valve on a water heater, plus the cost of the part. The whole job takes about one hour, so the plumber’s hourly rate will dictate what you pay. Your plumber may also charge a trip fee of around $50 to $75.
What to do if your water heater has an error code?
Control has sensed an error in the electronics of the valve and has shut down the water heater. If resetting the control does not clear the fault code, replace it. To reset the control, slide the ON/OFF switch to the OFF position. Wait for 10 seconds and move the switch back to the ON position.
Where is the temperature sensor on my water heater?
If the unit doesn’t come on and still codes, then you need to take the gas valve apart. Most newer water heaters use Honeywell gas valves. The Honeywell gas valve has a front, middle and back with temperature sensor and piezo ignitor connections in between.
When to replace a gas control valve on a water heater?
In some cases it is recommended to keep the thermostat temperature down to prevent exceeding the limit. 5 – Replace Gas Valve This indicates a sensor failure and the gas control valve must be replaced.
What to do if your water heater has a gas failure?
Gas control failure, replace the gas control valve assembly. Check that the gas supply to the water heater is on. Ensure the water heater is properly grounded and operating at 115-120 volts. Check the flame rod position and make sure it’s not oxidized, broken or disconnected.
