AO Smith Proline direct vent

[Peter Varieur]

Last night my hot water heater didn't turn on. I tried turning off and killing power and turning back on . The blower comes on but the heater won't fire up. It tries this for a number of cycles and then stops. It's an electronic ignition and direct vent Proline XE . Could it be the igniter, it's only 3 years old ?

It was my power vent fan. not pulling enough air to open valve.
