Hi everyone! I am having some issues with my old hot water heater and wondering if anyone knows the fix.
The pilot lights just fine and when I turn it on the flame is strong. However, after it runs for a few minutes the flame cuts out and there is a squealing sound for a moment. Then the flame comes back on and the squealing stops. It does this intermittently and seems to get worse as I leave it on longer. I’m also seeing a small combustion when it makes the sound at the back of the burner where the air adjustment is. Does anyone know what is causing this?
