I have an A.O Smith water heater ( power shot) it has an control box with self diagnoses. The "A" & "B" lights are Illuminated. If I cycle the circuit breaker it will work normaly for about a half day. The trouble shooting guide saya it could be 1 of several things, low gas press, low volts & hot surface ignitor not positioned correctly. Checked all now what ?
