goldstream wing 3
Our Goldstream Wing 3 camper came with a Dometic 3 way 90litre
fridge/freezer. While this may be fine in cooler climates it
struggled to maintain the minimum 5 degrees Celsius for safe food
storage in the Queensland heat. I was going to replace it with a
compressor fridge but decided maybe it can be improved to make it
Looking at the installation instructions that
came with the fridge it seems to be installed to spec with the
exception of the top vent not being above the top of the fridge.
Being a wind up camper that just canít be done (its level with the
top of the fridge).Looking over the many posts on this on the
internet I decided to try fans to assist the cooling. Firstly I
installed a 120mm fan to the exhaust (top) vent using cable ties to
hold it in place. I included a plug in the supply line so I can
remove the vent entirely if need be. This fan helped but was not
what I had hoped for.
Next I installed a 90mm (biggest I can fit in
the space) at the bottom of the condenser coils to assist with
cooling. This fan made a huge difference to the cooling efficiency.
Suddenly the fridge was cooling much better.
After reading many post on the internet I read
that many people have had success with putting a fan inside the
fridge to help with air circulation. I originally had a tiny 40mm
fan in the fridge but it was too small to do anything, so I replaced
it with a 80mm version. This fan sucks cold air from the bottom of
the fridge and circulates it around the fridge. The small wires go
through the water flow pipe opening to the back of the fridge and
connect to the other two fans. This fan seems to help with reducing
the water in the bottom of the fridge and also stops the cooling
fins from icing up and maintains an even fridge temperature. This
also helps with things being frozen overnight.
All fans are wired via a 90 degrees Celsius
thermostat cable tied to the evaporator tube about 75mm from the top
of the heat unit. The idea was the fans would go off when the fridge
cycled off. It may never do that...I have also put in a switch to
turn the fans off if need be. All 3 fans are 'silent', and are dust
and waterproof and draw a total of 0.35 amps. Thatís around 8.5 amps
per day, but itís a small price to pay and easily replaced with the
solar panel. All three fans have a guaranteed life of 100,000 hours
at 40 Celsius. All you hear is a very slight hum which is hardly
I also installed a Fridge Switch which disconnects the 12volt supply
when travelling after three minutes of Ďnon movementí. Helps
draining to main battery rather than relying on the battery
Original fridge ĎAuto cableí wiring in front of
Fridge Switch. Replaced with 6sqmm cable.
The fridge is running on 240 volt at the moment
and is maintaining between 2 and 4 degrees Celsius. Fridge
thermostat is set to half. The freezer is holding -15 Celsius.
Ambient temperature is currently 30 Celsius. I also have two 500ml
bottles of water I froze and placed in the fridge. Helps get
temperature down initially and although thawed helps it recover
quickly when opened. It should do better on gas.
Total cost around $200 for the three fans, thermostat, Fridge Switch
and associated wiring.
