See chapter 5

5:3 Safeguards
Protection is provided for the following:

(1) Low voltage. To prevent the batteries from being totally discharged, the
compressor will be
stopped if the voltage at the terminals on the controller falls below
10.4volts (22.8v on a 24v
system). It will not re-start until the voltage rises above 11.7 volts (24.2
on a 24v system).

(2) High voltage. If the voltage exceeds 17v, the controller stops the
compressor and switches
into 24v mode, but will not attempt to start the compressor until the voltage
reaches 24.2v.

(3) Compressor non-start. If the compressor does not start, the controller
will stop the starting
process and attempt a re-start approximately every 45-90 seconds.

(4) Compressor speed too low. If the compressor speed falls below 1900 RPM the
controller
will stop the compressor.

(5) Fan (and pump) protection. If the current draw across the fan terminals
exceeds 0.7 amps at
12v dc, the compressor will be stopped and a re-start attempted every 45-90
seconds.

(6) Module overheat. If the heat sink on the controller exceeds 100 deg C (212
deg F), the
compressor will be stopped and will be re-started when normal operating
temperatures are
resumed.


I think you should demand your money back under warranty as it's simply
not your fault of the compressor baked the oil. (If, indeed, it truly did
which
I doubt.) The only way that can happen is if the Module overheat function
failed to work as advertised.

Sir Gregory, Danfoss BD50 compressor is not protected by a thermo or high pressure switch as are other sealed compressors. Compressor protective control is handled by electronic control module If module itself were to over heat Yes compressor will stop. There are conditions in these water cooled systems where BD compressors without adequate cooling will run very hot.

On my Adler Barbour, the controller is about an inch from and downwind
of the compressor. Hot air blows around the compressor right onto the
controller and since it is so close it can accurately be set to turn off the
compressor before gets hot enough to damage itself. There is even an
LED code to notify a user of what fault condition exists (five led's).

It would appear from reading the .pdf file for the Frigoboat that they
use a very similar, if not identical, controller set-up.

Given that Frigoboat uses the same or similar set up. I still say Skippy
needs to put in a warranty claim because what's the use of overheat
protection in the controller if it fails to shut it off when overheated?

Sir Gregory, You will not find in any of Danfoss BD documents covering compressor troubleshooting any reference to compressor protected from refrigerant flow damage do to excessive heat. Item #5 refers to high amperage shutdown do to poor condenser cooling. On water cooled BD compressors only the refrigerant removes compressor heat. You would thank very high compressor oil temperatures and pressures would cause high amperage that would trigger module to stop compressor but it does not when refrigerant return compressor cooling is restricted.
