We have a Bradford White gas hot water heater that isn't working properly. We'torn it apart and cleaned everything and have seemingly figured out what is wrong with it but we aren't totally sure. What is happening is, a green control light comes on the pilot sparks and lights, then the pressure switch (TDI, Inc.) starts clicking and it shuts down. We have found that if we clamp off the pressure tube leading to the switch the pilot light will stay light and the water will heat, but then the vent gets really hot so we don't want to continue to do this because it's most likely not the safest thing. We are thinking that it is a bad pressure switch; but someone else told us that they rarely go bad and our vent could be blocked. We went outside and checked the vent and it appears clear. Should we replace the pressure switch or is it most likely something else? I don't want to hunt down a switch if that is not going to fix the problem. Also, is there any other way to check the vent?
