1. The First Bulletin said nothing about freeze ups. Just that they had a problem with leakers on 2 percent of the units. The problem cropped up in the first year of ownership, so if you had a suspect unit after 2 to 4 years, odds are yours is OK
2. The 2nd link is 20(TWENTY) years old. The freeze sensor shown has been discontinued years ago(about 16 years). You will note that IT is installed at the bottom of the coil. YOU stated yours was in the MIDDLE, which is where the RV maker installed it, not Dometic. Sooo, if you had freeze ups on the 1st 2nd and maybe 3rd unit, LOOK AT YOUR INCOMPETANT Service person. They should have KNOWN the sensor was NOT in the correct place. At the bottom area of the coils about 1 to 2 inches up.
3. AS I STATED, if you had freeze ups, and had the Freeze Thermister and installed in the correct place, your units could not freeze up. Maybe not cool correctly but not freeze up.
4. I guess people do not need knowledgeable Service people, just look it up on the Internet. There is NEVER bad info on the Internet. Or info that when read, will be taken out of context.
5. Since you think searching the Internet makes you smarter than me, look at page 6 of this link. Doug
