I have a Norcold fridge in my 2006 Komfort Trailblazer. The fridge gas solonoid buzzes all the time. This is killing my batteries. The fridge is working properly as it should, but I don't think it should be drawing power all the time. When I disconnect the power to the solonoid, it stops buzzing, but as soon as I hook it back up, it starts buzzing again. It seems like the solonoid is being held open to allow gas to flow all the time, however the fridge appears to be operating properly, so I'm not sure if the solonoid is drawing power, but the valve is still closing when not needed or what. Any help is appreciated.
