Now I’m starting to wonder if the short return tube is correct for the RDS-30C. Parts diagram shows 314332 as the correct tube. This is 5″ longer than the inlet tube. When I dropped the lower unit it originally had the longer tube. I figured it wasn’t connected and was the wrong tube, but perhaps it was connected into the lower grommet. I replaced it with a short tube I had which fit into the upper grommet next to the outlet tube. Maybe not correct? There is a short tube running from the bottom of the housing cap to one of the lower grommets. Perhaps the long tube is correct and fits in the other lower grommet?
UPDATE – I reinstalled the original long return tube into the bottom grommet and she’s cooling fine now. So I created my own problem by putting that short tube in. Glad I figured it out.
