I installed this Sears 153.332960 power vented heater as a replacement and it ran perfectly for 2 weeks. Wife then heard unusual (loud) sounds during operation, probably from the burner area, and turned it off electrically. She was too scared to worry about exactly where the sound was originating! Now, it will not run at all. When the heater is switched on, all LEDs light up, dim slightly and after 2 sec there are two 'clicks', the lights go out and nothing more happens.
The power vent does run when powered directly 'off-line' and sounds normal. Apparently it is not being called for by the control circuit as I think that's the very first step of the on-cycle. Can someone confirm that?
The 'new' unit is actually 7 years old so no warranty. When I bought it, the cost of the whole water heater was only about $100 more than the replacement part I needed (failed power vent). I grafted the fan only of the new power vent system onto my original water heater where it performed without incident for those 7 years. Recently the old tank developed a leak around the relief valve so I replaced it with the unused tank and its original, now used, power vent. The unit fired right up and ran the two weeks I mentioned earlier.
I'm wondering if there's anything else I can test myself!
Thanks for any help,
John
