The pilot won't light up

The pilot of the A.O Smith model GVR-40 (71 gallons) won't light up, i have tried to light up manually several times but it doesn't work. It worked fine yesterday until the water leakage and i replaced the drain valve.

Water heater pilot lights no burners


The thermocouple must be defective. Thermocouples convert the heat from the pilot into milli volts to open the gas valve. This is a safety to ensure there is a flame, so the gas doesn't just build up (that can cause an explosion)

We had to turn the gas off to connect the dryer, now we can't get the pilot light to turn on. we followed the directions on the water heater 5 or 6 times with no luck. It seems the pilot light will not...


I would suggest that you remove pilot assembly from gas valve and burner and clean pilot orifice and see if that helps. Be careful when cleaning hole in the orifice so you don't enlarge the hole. Good luck and thank you.

Gvr 40 100 will not stay lite


The Cold air screen on the bottom of the water heater is partially plugged. That is if the pilot light can be lit and stay on, but goes out when the heater should be functioning normally. This is not the removable plastic screen but a round white-yellow grid with 1/32" holes. You can try to clean it through the bottom but you may have to remove the gas line from the controller to the burner, pilot gas line, and thermocouple connection to remove that complete assembly to get access to the screen. The AO Smith booklet warns of this but they pretend the plastic screen will keep this second screen clean but it won't. After three years it was two thirds plugged.

Gas pilot wont stay on i think i need thermocouple dont know wha size to get or should i just get pilot assembly gvr-40 100 series


they are universal, the only thing youi need to know is how long it should be, most will take a 30inch, just to make sure you have enough, our oyu can take the one out that you have and match it up, the one you take out will actually measure a little shorter then the new one which is ok, just make sure you put the burner assembly back in the perch correctly, if not you will have bigger problems then you want to have

Waterheater pilot light keeps going out


There are several things that can cause this, but the most likely cause is a dirty pilot light orifice, causing the pilot light to have a smaller weaker flame than it was designed for. This produces a weak flame that is easily susceptable to drafts, and a lower holding temperature on your safety capillary tube that controls the gas shutoff safety valve.
The orifice can be removed and cleaned on some models, removed and replaced on others. I would suggest a qualified serviceman be called, because gas service is usually beyond a typical handyman's area of expertise, and safety is a very important issue here.
