My boat has an Isotherm
5801. That's the dual Danfoss compressor
unit. The unit cools down a freezer
holding plate in the freezer
and there is a spill over refrigerator
The PO ditched the ASU module because they kept blowing up on him. [Nice, guy, but he seemed to have that problem with a lot of electrical
things on the boat.
Instead of the electronic control module, he has the old standard temperature switch, which was incorrectly measuring the freezer temp. I moved it to the refrigerator
compartment to bring the unit down to proper temps.
The refrigerator keeps stuff at the appropriate temp in both the freezer and the refrigerator.
Works fine, usually.
EXCEPT... on occasion, the unit will run for about 1 minute, then switch off for 2-3 seconds, then run for one minute, then switch off for 2-3 seconds, over and over again.
I'm trying to figure out why this is happening. The refer and water
circulation pump (water cooled) both shut off during that 2-3 seconds. It seems highly inefficent for that to be happening and probably a bit of a wear/tear issue as well.
So far, my theory is that the refer is trying to go into some automatic mode it no longer has...
Any ideas? Anyone with an Isotherm
ever experience this?
I tried going to the Isotherm site for support, but it's not loading well...
