I know, stupid question – but did you make sure the variable orifice valve (VOV) was installed the correct direction? Was it missing the O-ring or loose when installed? I think VOVs are great but unfortunately they don’t always work for older applications. Some people get away with no issues, others rip them back out and put the orifice tube back in.
