Ge gg50t06pvt pilot wont light - Vanguard International Vanguard BY Rheem G91-200LP Gas Water Heater

bad piezoelectric generator.

If it's not the thermocouple, then the control valve might have failed. There isn't much else that can cause this.

does the pilot go out when you let off the button? Or does the pilot not light at all?

If you dont get any gas at all to the pilot the the gas valve is bad.
Of you get a pilot light that goes out when you let go of the button then the therno couple is not reading the flame (needs adjustment so the pilot flame touches it)
did you kink the new thermocouple? or over tighten it at the gas valve.
if it was kinked its now toast,cant straighten them. If kinked and starightened the fluid inside has broken the inner seal and wont work.

I had a situation like this and it turned out to simply be the build up of residue where the flame comes out. I cleaned it with spray air, like you use for electronics. Once cleaned it re-lit to the proper size to maintain slight contact with the burner. Hope this helps! It wont hurt to try before calling for service anyway!

The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If flame goes out it shuts gas off to the pilot jet. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced

I believe this unit does not have a standing pilot light and lights each time? Have you reinstalled all doors back into the heater? It sounds like the main burner is blowing the pilot off the thermocouple. You might try replacing the thermocouple.

can not start my whirlpool natural gas pilot light

need a new one.(pilot light)

Hi,
First thing is to replace the thermoscouple. When you light it you get it a bit hotter then normal. You turn on the main burner which keeps it hot. Then when it goes back to just pilot the flame is not hot enough to hold the pilot valve in.
Replace the thermocouple and you will be fine...

Probably a bad solenoid in the gas valve. Higher voltage of a new thermocouple keeps it open longer but it still fails over a period of time. Look into a new gas valve for the water heater.
