AO Smith water heater burner wont stay lit.


It is a AO Smith promax GCV 40 100 water heater to be exact. I can get the pilot to light may take a second or two to keep it light but when I turn it to the on position and turn up the temperature the burner lights. It goes out along with the pilot light after a minute or two of heating. I do hear a slight "click" when it goes out. I have tried cleaning it to make sure its not starved for oxygen, didn't help. I checked to see if its under warranty and it is not. PLEASE HELP!

Is that a sealed unit (no door to the burners--clicker to light--little glass window)

or an open unit--(removable door light with a match)?

Yes, it is sealed. Glass window with clicker to light.

Call a plumbing supply house --you may not be able to buy the parts you need--usually only sold to licenced plumbers---either the thermo couple is dead or the flame sensor is defective---often the whole burner unit must be replaced---sorry---

Ben--I don't know about A.O. Smith--but most of the sealed units I have delt with can not use a universal thermo couple---Must be original equipment---different threads---

Good news on AO Smith--It was two Whirlpools that had me stopped---AO Smiths are better units and I have never needed to service one---

Mike is right they cannot use universal thermo couples. Good news though I took out the whole assembly and scrubbed it down with a wire brush. Although it didn't look dirty...I re-installed it and its working fine now. Hope its not temporary. I thank you again for the time spent with me.

I'm still fighting with my water tank. Going to try to bleed it first. Easter filled my days. If need be, how would I go about taking out the whole assembly, like Fortypopper mentioned?
