How do you test a vapor water heater?
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.
How can I replace the vapor sensor in my hot water heater?
If you have access to a Radio Shack or electronics store, you can pick up a 15k-ohm resistor. Tie it into your hot water heater, and you will have bypassed the safety mechanism of your hot water heater. Replace the vapor sensor. If you have a bad sensor, the fix is easy—get a replacement and install it.
Where is the FVS on my water heater?
My FVS is situation on the edge of the water heater in a plastic cover. The sensor looks like a power socket plug. 25VS. The little guy that stands between hot and cold showers. When the sensor detects a sensitive fume its resistance increases and closes the circuit.
What to do if your hot water heater has a bad sensor?
Tie it into your hot water heater, and you will have bypassed the safety mechanism of your hot water heater. Replace the vapor sensor. If you have a bad sensor, the fix is easy—get a replacement and install it. Many of the big box chains like Lowe’s and Home Depot will unlikely carry these parts, but a specialized plumbing company might.
What does flammable vapor sensor in hot water tank mean?
My control unit produced a sequence of 7 flashes, which indicates that I have a faulty flammable vapor sensor (FVS). The FVS is a relatively newer’ish invention that consists of a silicone type sensor that detects flammable vapors outside of the hot water tank.
What is the Bradford white water heater safety system?
The Bradford White DEFENDER Safety System® The Bradford White DEFENDER Safety System®was designed to resist the ignition of flammable vapors that can occur outside of the water heater. Use and installation are nearly identical to previous versions of atmospherically fired and vented water heaters.
What is the Bradford White defender safety system?
The Bradford White DEFENDER Safety System®was designed to resist the ignition of flammable vapors that can occur outside of the water heater. Use and installation are nearly identical to previous versions of atmospherically fired and vented water heaters.
What to do if your hot water heater has bad vapor sensor?
Mega amounts of resistance indicates a bad vapor sensor. One hack to get your hot water heater going in a pinch (DON’T DO THIS) is to install a resistor in the circuit. If you have access to a Radio Shack or electronics store, you can pick up a 15k-ohm resistor.
My FVS is situation on the edge of the water heater in a plastic cover. The sensor looks like a power socket plug. 25VS. The little guy that stands between hot and cold showers. When the sensor detects a sensitive fume its resistance increases and closes the circuit.
