Got a call for on an A.O. Smith W/H with intake air error codes. I removed cleaned the leafs on the filter and performed a basic maintenance. Does anyone know what range the flame rectification on these should be? I had close to 7 micro amps, but no error code regarding the flame sensor. #hvac #plumbing #residential #learnme #aosmith #service
