The photo I posted from PartsTown was for my own info as well as to post here. Using the photo link’s partSPIN feature (unique to PartTOWN), you can rotate and zoom in to read the sticker on the part. It says it’s rated to 35 psi. From the picture, I also wanted to see if it’s maybe a screw-on type pressure switch that would possibly be designed to mate with a flared fitting w/Schrader valve (It’s NOT. That’d be too easy).
The picture definitely shows it’s open-ended, with clear cap over the opening to keep it clean. So, at best, it might just require a pinch-off tool, torch and a stick of sil-fos…if done perfectly.
However, the charge weight in that little machine varies from 9 to 13 ounces – depending on the version of ice maker. A model ICEU150A4 states 12 oz of 404A. Ed said ICEU150HA4, which I couldn’t find. Anyway, that ain’t much refrigerant at all, so if some leaks out, then might as well pull the charge and weigh back in the exact amount.
Right, I think back to about 3 years ago I remember working on a couple of these and I installed a new one 2 years ago. I specifically remember that Mile High silver brazed a control line right into the suction without the use of any fittings. If in fact the switch is bad, one would best have a expanding flare set and just cut the line as far out as possible before it reduces to the cap . Expand the new one and braze over the old. .It of course requires recovery and a tap install, new drier, and vacuuming.
Had to go through my field notes and pictures to remember. Mile High makes this machine for others as well. I installed a Manitowoc replacement and it was identical part for part.
