BradfordWhite Water Heater won't stay lit


My 5 year old Bradford While water heater will not stay lit. The Blower is working and I am getting good pressure. The pilot lights, followed by the main burner with nice blue flame. After about 90 seconds, it shuts off. If I unplug it, the same thing will happen, but this time the main burner will shut off in about 20 seconds.

Odd thing is, the blue flame starts to turn a little yellow and I get a few drops of water (perhaps condensation? Basement tempature is about 50 degrees.) There is certainly no puddle so there can't be a major leak.

I removed the pilot ignition and sensor (honeywell Q3400A1008) because , but perhaps the sensor is not working. (I don't have a volt meter). It looks clean.

Any ideas?

Thanks,
Mike

The water is condensation. Cold water hot flame...I would expect that the valve isn't proving flame. While I'am not familier with this exact mod. With the exception of a few... most All electronic ign. gas equip. must prove flame to stay on

any possibility the condensation is dripping on the pilot assembly and extinguishing the flame?

I have seen that happen. It should correct itself once the water heats up. If it keeps goung out. Then you have other problems . Vent ,valve not proving ignition, Etc, Does this mod. have a vaccum switch ?? If so jump it out & see if burner stays on. Don't leave it jumpet out
