Those who were at Hedlow would remember my Waeco Fridge/Freezer giving up the ghost while I was up there. Just to give everyone the story.
Put the fridge on 240 volt power at home and cooled it down to 2 degrees and filled it full of everything I was taking with me and kept it at that temp overnight before I left. Placed it in the car and plugged it into the 12 volt system and away I went.
Arrived at Rockhampton about midday and bought the meat to take out to Hedlow. Got back to the car and noticed the fridge temp was 7 degrees. Thought that was a bit odd and headed out to the camp.
Set up the camper trailer (yep Skip, it easy for one person

) and went to pull the fridge out of the car and now at 9 degrees. While watching it a small error light was flashing about every 5 seconds or so. Couldn't get it to run properly so had to scrounge space in others fridges and eskis for all my stuff. Pissed off to say the least.
On arrival home plugged it into the 240 volt power and away she went. Cooled off to -2 in no time. Plugged back in the battery and nothing. Read the Waeco documentation and all indicated that there was low voltage. Weird so tried it on three different 12 volt sources and still the same.
Rang Waeco and told them the story. Guy on the other end of the phone was very helpful and his diagnoses was that there was low voltage. Told him all that I had done and his response was they would need to have a look at it.
Nearest agent was just down the road at Browns Plains so dropped it off there. Five days later received a call that it had been repaired. On pick up I naturally asked what the problem was. They told me it was the
poly fuse
. Hmmmmmmmmmmmm, what's a poly fuse, I asked as I had never heard that term before. It is a small fuse soldiered into the circuit board. Looks about the size of a postage stamp and a little thicker.
Ok, what caused it to blow? Was told that, like a lot of equipment manufactured these days, they put in the very minimum they can get away with. Great, so it's going to blow again sometime and I will never know when.
Nope, says the guy, we put in a bigger one as we always do.
Sooooooooooo fridge is home. Filled it up with cans and cooled it down to -1 degrees on 240 volt power then switched it over to 12 volt and run it on that for 2 days and all is going well.
Did a search on Google for 'Waeco Poly Fuse' last night and guess what? Common problem.
Overall though it was repaired at no charge to me so thank you once again to Waeco. They have been pretty good to me over the years.
