My dryer when drying will make a buzzing noise just before the burner ignites. I have an extended warranty and had a service tech out. He said after hearing the noise it was the gas valve assembly. He replaced it never did any diagnostics on anything to prove his decision. Unfortunately it still has the same problem. I called them and they returned same tech. He says now its the gas pressure on the line coming in. I should call the gas company or plumber to check it out. Do you have any insights to what might be the problem?
ANSWER Joe, Improper NAT gas pressure ( 3.5 WCI +/- 1 WCI) can cause the valve solenoids to "chatter" So you may want to have the gas company check the pressure"under a load". The more likely issue is a loose connection, improper crimp, or something similar in the wiring harness connections at the motor or gas valve connector. Good Luck and Thanks
