Frustrated - HWH pilot going out once a week

Hello thanks for looking. I have a A.O. Smith ProMax plus hot water heater. It mostly works just fine but will intermittently go out. Sometimes it will be twice in 2 days. Sometimes it's once every 2 weeks. This has been occurring for about a month. I want to get a tech out to have it serviced but I'm wary and don't want to get the run-around. It can be a little tough to light once it's gone out but nothing too bad. Just have to hold the gas down for 20/30 seconds before it will catch.

Any ideas? What type of service person etc. would be great.

Thank you!

Welcome to the forums.

Not my department but here in NJ our natural gas supplier offers servicing of gas appliances.
Otherwise a plumber may be of service.

One question..... do you have an attic or big exhaust fan that could be pulling a draft from there and blowing the pilot out ?

Here in my house..... if I don't open the windows before putting on the whole house fan.... the HWH pilot gets blown out.

A.O. Smith ProMax plus
Model # GVR 50 100
50 (gallon I assume)
Serial # is pretty scraped up but i believe it's:
GE340063444

The unit is outside in its own cabinet and I believe it is not connected to an attic or exhaust system.

Thank you!

Its a series 100... Most likely the air intake disk is clogged with lint... Is called a corderite disk... The unit may be starving for air and it trips the thermal sensor, which shuts the gas off...

You are able to relit only when it cools down....The burner chamber gets hot because of this clogged air intake.......

Most likely needs to be vacuumed... Need to make a tool to do so...

There are many post regarding this on DIY. Do a search, or I will try to locate them myself and post back later...

Service tech if you choose to call one, just call AO smith and ask for service reps in your area... You can go on their website too and put in your zip to find one...

5 25 30 58 59 PB 32

Oh wait... you wanted FUTURE numbers?

I can't remember where on-line I saw it sold, but I happened to come across a vacuum cleaner attachment that was flat and thin and would fit under the heater to vacuum the disk off... maybe you can make something yourself?
