Our water heater pilot light won't stay lit. The original code was #3 for insufficient heating. I replaced the thermopile and pilot assembly. Now the code is #5, sensor failure. If that was the problem, why didn't that code show to begin with. Does it need to be reset? Can I just replace the sensor or do I have to replace the whole gas valve? Thanks so much.
