Texas Pete Posted August 9, 2023 Share Posted August 9, 2023 Hey Guys (and Galls!), After a while in the shed I am getting my '90/24k back on the road again. All is well except the AC. As its 100+ deg in my part of Tx at present I need it! The compressor will not stay engaged, so I have shorted out the return pressure sensor. While doing that I noticed signs of the freon leak detector (yellow) dye around the base of the sensor. Does anyone know how it is sealed, and/or a PN for the seal? It is still running on R 12. I don't want to disturb it until I have parts and R 12 to fix it. Paying nearly $50 for a 4oz can! Link to comment Share on other sites More sharing options...
Ronnie Posted August 10, 2023 Share Posted August 10, 2023 I believe the low pressure cutout switch is sealed with an o-ring. It can be changed without losing freon. There is a Schrader valve under it the will keep the freon from escaping if you screw it off quickly. I don't know the part number for the o-ring.

Texas Pete Posted August 10, 2023 Topic Author Share Posted August 10, 2023 Thanks Ronnie! I also have a can of Proseal, which is supposed to stop any small leaks. I may throw that in first in the hope it fixes it. Link to comment Share on other sites More sharing options...
Ronnie Posted August 10, 2023 Share Posted August 10, 2023 I think the money would be better spent on a new low pressure cutout switch that probably comes with a new o-ring but the sealer might work. Link to comment Share on other sites More sharing options...
Texas Pete Posted August 10, 2023 Topic Author Share Posted August 10, 2023 Good point. I will see if I can track one down. Link to comment Share on other sites More sharing options...
