Question about Water Heaters
I have an AO Smith GPVH 50 that is approximately 18 months old. Just this evening, it decided to stop heating. I followed the shut-down/restart process (waiting 5 mintues) and the electric probe glows bright orange and the burner initially lights. But, 15-20 seconds after the burner lights the system shuts down again. The system keeps trying to restart but the burner will not stay lit. Any thoughts...Brett
This system uses an electrical test to make sure that the burner is lit. The flame sensor will either be broken or will be covered in deposits (clean with an emery cloth).
The flame sensor is usually a small metal rod that would be in the direct line of fire of the burner with 1 wire attached.
The ignitors can be very fragile and are expensive. They are very brittle, do not touch it.
