Hi

ITEM
3 year old 40 gal gas water heater.
Uses natural gas
All plumbing and venting 3 years new.
Mounted on two foot pedestal in garage.

Pilot went out Sunday.

Relit Pilot ok
Burner would not fire.

Tried several times over five hours with pilot off, relite no burner.

House water was hot all day.

House gas furnace was functional so not a gas supply problem.

Later that nite Burner fired up

Is this a problem or sign of failure to come?

It sounds like the thermocouple is weak or misaligned or the pilot jet
may need cleaning or adjusting. None of those are expensive or difficult to
do.

I am not sure what "Tried several times over five hours with pilot off,
relite no burner." means. If you mean you tried to turn on the burner
without the pilot on or right after lighting it, that could be your problem
The main burner should not light with the pilot out and it may take a few
seconds to warm up the sensor to allow the main burner to kick in.
