Can you jump out flammable vapor sensor?
Unfortunately, they tend to spontaneously fail and whether there is vapor or not, your water heater will not turn on. If you count the pulses of the LED, when troubleshooting, and look at the service plate, it will tell you if the detector has sensed flammable vapor (or died). You cannot easily bypass this sensor.
How do you test a flammable vapor 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.
What causes flammable vapor sensor lockout?
What is a Flammable Vapor (FV) Sensor? FV Sensors are safety devices on select models of water heaters, which cause a soft lockout (a.k.a. the unit shuts down) when flammable vapors are detected near the unit, to prevent the possibility of their ignition.
How does a flammable Vapour sensor work?
The carbon, which acts as a conductor, is dispersed throughout the silicone such that, in the absence of gasoline vapor, the carbon particles are in solid electrical contact. When the silicone encounters gasoline vapor, it ex- pands, pulling some of the carbon particles apart, increasing the resistance of the sensor.
Where is the flammable vapor sensor located?
Open doors and windows for ventilation while flammable substances are in use. The FV sensor is located on front of many water heaters today. The sensor will trip if it senses gasoline vapors in the air.
How do you reset a Rheem gas valve?
Turn the water heater’s gas valve switch to the “OFF” position, wait for a few seconds and then flip the switch to the “ON” position to reset the system. The water heater’s gas valve is located near the bottom of the unit and connects to your home’s natural gas line.
What does a flammable vapor ( FV ) sensor do?
How to reset flammable vapor sensor on water heater?
Reset the control by unplugging the blower, leave unplugged for at least 5 seconds. 2. plug back in and within 30 seconds cycle temp control from hot to low 6 times. Robertshaw Gas Valve: 1. Turn the manual lever on the Control Gas Valve counter clockwise until it snaps to the “on” position.
Can a gas leak trigger a FVS sensor?
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. If you have a gas leak, you certainly don’t want to have an open flame feeding off that fuel. The downside of the sensor is that it can be trigger by other fumes in the vicinity such as paint fumes.
Where is the FV sensor on my water heater?
FV Sensors are typically found on power vents, damper models, and draft induced water heaters, powered by Natural Gas or Propane (presence of FV Sensor is determined by model). If your manual or heater specs say “FVIR,” your heater is Flammable Vapor Ignition Resistant and has an FV Sensor.
