Being a live aboard, I have to defrost my freezer plates every other month. The fridge life is well sealed, but constant opening causes frost to build up.

I haven't fixed it yet. -- Dennis C.Touche' 35-1 #83Mandeville, LAOn Fri, Jun 19, 2020 at 10:29 AM Dreuge via CnC-List <cnc-list@cnc-list.com> wrote:Hi Dennis,I have the Isotherm 3751 ASU SP system and I experienced something similar last Fall. The unit was alternately flashing yellow/red and was not working. I shut turned off the power at the breaker, clean up the defrosted moisture in the bottom, and threw out the mayo, mustard, and ketchup. I turned the unit back on and it started working. I started reading up on Isotherm ASU trouble shooting, but the unit has been working fine since. Prior this occurrence, I noticed a good amount of frost build up on the cold plate which I attributed to a poor seal on the access lid. I have since improved the lid seals and added a 1” foam mat (cut from an exercise mat) to cover over the whole top. I don’t know if it was the power cycling, some odd frost build up issue with ASU, or something else, but the units has been continuous running fine for over 7 months now (knock on teak). -Paul E.1981 C&C Landfall 38 S/V Johanna RoseFort Walton Beach, FL
