Frigoboat Compressor and Module Problems

[GYPSY SONG]

We installed two keel cooled frigoboat systems two years ago for a fridge and freezer. Worked perfectly until about 3 months ago. Since then we have been through 6 modules. At apparently random intervals the compressor will not start (three red flashes). Occasionally we are able to restart the compressor by shutting off the breaker and waiting for 5 minutes before turning the compressor back on. This will work a couple of times, but then it simply will not restart. This has led to replacing the module and everything will work fine for a few weeks - then it starts all over again. Of course, the 2 year warranty on the electronics has expired. Any suggestions on what might be happening? We are currently on a mooring ball in Marathon, FL - it is pretty warm and humid - could this be the problem?

Make shure that you have the appropriate wire and beaker size for the unit. As well the compreser needs to have as much fresh air to keep it cool as possible.

If unit has run faithfully for two years would be inclined to think original install was acceptable. I would be looking at and cleaning every power supply connection whether it appears good or bad. If you find any darkened/discolored insulation is dead giveaway it has been hot. Hot = poor connection. Love digital test equip but for this issue a decent analog meter connected at the condensing unit can show you things a consumer grade digital meter may not such as a voltage dip at startup.

I'm assuming unit has not been overcharged or non-condensibles introduced.

The Frigoboat compressor (a Danfoss actually) is sensitive to low voltage and it will not start if it is too low. Make sure that the supply is at least 12 gauge (I know that this is overkill, but hey it works) and that all connections are good and tight.
