My 406A has had a rattling noise in the header. It shuts itself down and I suspect the Unitherm Governor or bypass or both is the problem.
I can't get the square retainer bolt out. Any suggestions? It is not in that bad of shape but had Leslie's pool come and he had a simple crescent wrench he couldn't get it open with. Here is a picture of square bolt- . The end problem seems to be flow is constricted and overheats and get ignition failure as faults. Checked everything else out. Any guidance?
