Hot Water Heater Sensor Failure Meaning You can tell that the water heater has a problem because the water is either too hot or too cold. But other factors can produce similar results, including a defective pilot light that refuses to stay on, insufficient oxygen, debris, etc.
What does sensor failure mean on a hot water heater?
The failure modes from mechanical vibration are similar to those from thermal cycling, caused by the gradual development of cracks. Electromigration failure of interconnected solder joints. Finally, electromigration is the most insidious of all, as it does not require any external influences.

What does temperature sensor failure mean on a water heater?
In simple terms, when the thermocouple does not sense flame, it prevents the gas valve from delivering gas to the burner. It is, therefore, a key safety element of your water heater system. Often a bad thermocouple is why a water heater pilot does not ignite or the burner does not stay lit.
Where is the temperature sensor on a water heater?
Short answer/ Gas water heater thermostat: Gas valve control has a thermostat located on the back of valve inside a copper tube that protrudes into the tank. The thermostat is a thermistor that responds to heat by producing a small electric current.
How do you test a water heater sensor?
Using a multimeter to check resistance, remove the sensor from its bracket on the base ring of the water heater and disconnect both wires to the sensor. 2. Take a resistance reading between the two wiring terminals of the FV sensor and note the resistance value.23-Sept-2019

Where is the temperature sensor located in a house?
The thermostat sensor is located near the evaporator coils. These coils are inside your air conditioner unit. As the air is sucked through the return vents, the air passes by the sensor and the coils. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat.
How long should a water heater last?
It would be nice to know when the time is right to replace your water before it springs a leak and causes an inconvenience or worse yet, damage to your home. Typically a residential hot water heater lasts between 6 and 13 years. Beyond 12 years, you are on borrowed time!19-Apr-2012
What are temperature sensors?
A temperature sensor is a device that detects and measures hotness and coolness and converts it into an electrical signal.
Should water heater thermostats be set to the same temperature?
The majority of electric water heaters have two thermostats: an upper and a lower, located under two control panels. To ensure your electric water heater works as efficiently as possible, you should set both of the thermostats at the same temperature.

How do flammable vapor sensors work?
These sensors work by changing their resistance when exposed to flammable vapors and other substances like cleaners used near the sensor. When the resistance goes out of the designated range, the control senses this and won't let the water heater fire up.
How do you test a Rheem flammable vapor sensor?
Flammable Vapor Sensor Location / Testing sensor from it's bracket on the base ring of the water heater and disconnect both wires to the sensor. Take a resistance reading between the two wiring terminals of the FV sensor and note the resistance value.
What to do if water heater doesn't come on?
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.
How to test a thermal switch?
How to test the thermal switch. Remove both wires from the thermal switch, set your meter to ohms, and put one of the leads on one of the connection points and the other lead on the other connection point. If you get a continuity reading, then it is good.
Why do you need pin probes?
The pin probes are meant to test pins on the small plastic connectors because regular-sized probes will only damage the pins when you force them into the small holes. Before you get into how to test the temperature sensor, try power cycling the unit.
