Jimbo are you sure about the 5 flash thing? I though it was 5 too but this says otherwise.
Since the flashes are for low RPM then it could be voltage related but then why would it not give the one flash? I'd check the wiring first anyway.
This is from the Waeco FAQ page

One Flash
Can be caused by:
• Insufficient cable size
• Too many connections
• Poor connections
• Not designating fridge

If the error light on your fridge flashes once every 5 seconds, it is
definitely indicating that you have a voltage drop problem. This
means that the wiring in your car may be inadequate to carry the
correct amount of volts to the fridge. To test if this is the problem,
plug the fridge into a suitable AC adaptor. If you find that the
fridge works, you can eliminate that there is a problem with the
fridge and the car wiring configuration or plug connections
should be stringently checked.
We recommend car/motorhome/caravan wiring to be a minimum
of 6-8mm cross section wire for up to 4 metres. Above this
length the wiring would need an extra millimeter for every metre.
If the fridge does not work on the correct Waeco AC Adaptor,
further investigation is required. Contact Waeco if this occurs.
Two Flashes
Fan over current cut-out
If the fan circuit in the control module has a load in excess of 0.5
Amps, the system will fail.
Three Flashes
Motor Start Error
If your error light is flashing three times every 5 seconds, the
rotor may be blocked or the differential pressure in the
refrigeration system is too high. Faulty compressor or faulty
control module.
Four Flashes
Minimum Motor Speed Error
This failure occurs if the compressor is running slower than 1850
rpm.
Flash Flashes
Thermal cut-out of electronic unit
If the error light is flashing five times every 5 seconds, the
refrigeration system has been too heavily loaded, or if the
surrounding temperature is high, the electronics will run too hot.
This is generally caused by not allowing enough ventilation
around the vents of your fridge. To overcome this, simply
ventilate your fridge more effectively.
