Question about Rheem Water Heaters
Model number 22VR75-70N
Maybe the gas control valve thermostat is bad.
Thermocouple is good because pilot stays lit.
The burner goes on so gas pressure is probably good.
Replace gas water heater

This is a major problem with Kenmore power miser 6, 9, and 12's - we purchased a Power Miser 6 in Nov. 2006 and have had 5 service calls in two years - we are on our 6th call now - Go to http://baheyeldin.com/technology-in-society/mistaken-identity-help-with-kenmore-water-heater.html or Complaintsboard.com and you will see multiple complaints on these models. We had Sears out days after we purchased the water heater, and had parts replaced, then more problems in April 2007 - It worked ok until Nov, 2008 and now it has gone out 3 times. We were told it is lint collecting on the screen that sits under the burner (difficult to get to) - we made a vacume attachment out of PCV pipe (like the one the repairman had) and vacumed the screen when the pilot light wouldn't stay lit - that is what they told us was the problem - but this time, the vacuming isn't working - Ash also builds up on the pilot light burner which has to be removed - you can't replace the thermal coupler without replacing the entire burner unit in this model - In short, if you can get your money back and buy a more reliable model, do it! Sears sold us a maintenance agreement after they had come out 3 times ($290), and still we go for 2-5 days without hot water waiting for them to come out and not fix our water heater. They also told us we should build a platform elevated off the floor to increase oxygen and decrease dust - funny our last model was still working at over 10 years and never had an issue in the same location! Sears installed the water heater, and should have installed it on a platform if that was what was needed. Also, there was no warning about having to vacume the screen (UNDER the heater - very difficult) - when we purchased this model or we wouldn't have bought it - Kenmore water heater repair line now tells you to try scrubbing the screen - but who wants to do this every month??? I can't tell you how inconvenient this has been - Looks like there was a class action suit against LOWE's which included the AO Smith water heaters (which is who built the power miser heaters) - no class action suit yet against Kenmore - This has been a nightmare and at the websites I listed, you will see many more such complaints, and some creative solutions...but I doubt any will work for long. Good luck.

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.

Called GE and there is a glass vile under the burner that is defective and cuts off the oxygen.
They are mailing out a replacement to my house & have contracted a plumber to install. waiting 4 days now. They say that the glass vile incinerates and there is not any thing left to it. The burner area is full of black soot. will post again one fixed.

Testimonial: "This is an accurate description of my own follow up. That device, a TRD, was the indeed the problem. "
the white rodgers gas control needs to be replaced;
the way it works is: the thermocouple opens the pilot gas circuit and, holds it open
when it heats up by creating a magnetic field in the gas control then: when you turn
the knob on the gas control to "on" a valve inside the gas valve opens the main gas circuit and, electricity supplied by your RV keeps it open.
the main gas coil inside the gas valve is defective and, can not hold the main gas circuit to the burner open anymore.
