      [Webinar] Appliantology Workshop   11/09/2017

      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

GE SmartWater SmartShield PG50T090AVH00 Pilot

Recommended Posts

I have a GE SmartWater (why do they use the same for heaters, softeners, dishwashers, etc -- makes searching real difficult!:X) Model: PG50T09AVH00 that was installed September 2005. 

It is installed in the attic.

A few days ago, we had a bad storm and the pilot went out.  (Don't know if it is related, but I have heard of high winds causing a vacuum and putting the pilot out).  I went up into the attic and the pilot re-lit with that piezo-electric starter thingy.  The water heated fine, but after the cycle, the pilot went back out. 

I have repeated the process at least five times now -- and I can get the main burner lit each time -- but when it goes out, the pilot goes out also.

Based on the my research, I'm thinking its probably the pilot valve assembly.  I assume that if the thermocouple was bad, it would shutdown the main burner also?

How difficult a job is it to replace the valve assembly (or whatever needs replacing)? I'm fairly handy, but have not worked much with gas appliances.

I haven't looked at any diagrams, yet, but,

is the Pilot Flame large enough to fully surround the Thermocouple nicely ?

(dirty Orifice) ?

Thanks for the quick reply.  Unfortunately, I cannot see very well into the viewport -- its blocked by a/c ductwork.  I can see the "glow" when the main is lit, but cannot get into position to actually see the pilot :(.

Now I can't get the pilot to light at all. 

I called the "help" line and they suggested I check the air flow -- blocked air intake at the bottom of the heater and plugged stack.  Air flow appears to be fine.  As a matter of fact, when I checked it the main burner was still lit and I could feel the hot (really hot - ouch) discharge gas leaving the top of the heater into the stack.
