isotherm model 4730 refrigeration unit stops cooling

[Michel C]

Hi, need some guidance. I have an isotherm refrigeration unit model 4730. seems that after a little while, the green light stays on but then the orange and red start to flicker and then the unit stops cooling.
It happens mostly when on shore power at dockside, and a few times while on the hook.
Anyone have the same issue? what was done to correct this etc.
much appreciated

Is it an air or water cooled unit? If water cooled then you need to check that cooling water is flowing by looking at the overboard dump for it.

it's the air-cooled. compressor has extra fans to ensure she doesn't overheat. Im starting to beleive it's an electrical issue. Probably not enough power getting to the compressor. Still searching though and any help is welcome. thanks

Michel C, We're neighbors I'm on C dock. Sorry don't have refrigeration so I'm not in position to help. Dock neighbor just installed an Isotherm unit on an Oday 31. He may be of some help.
