I just bought a brand new Whirlpool WGD6120HC0 Gas Dryer. Had a propane tech come over and convert it to LP and hook it up for me. All of the drying functionality seems to be working properly, but the end-of-cycle buzzer comes on whenever the flame is ignited and stays on until the flame turns off. Both the tech and I are scratching our heads at this one. We double checked all the wiring and tested for the proper amount of gas. Anyone ever urn into this before?
