I have a Thetford 3 way fridge. For the second time in three weeks I am sitting in a caravan park waiting to have it fixed because it won't work on gas. If I stay in a freecamp and run it on battery overnight it runs the battery right down (I have two 80 watt solar panels and 120 watt house battery. I have spoken to a couple of people who have Engal two way fridges and they can freecamp for three days on battery on less power than I have available.
Are 2 way fridges built to use less battery power? My fridge is still under warranty (six weeks old), but so far it has cost me over $600 in caravan park fees waiting around for it to be fixed. If it plays up again I'm wondering if I should change it for a two way Engel or similar.
I would appreciate some advice as to the best way to go.
A three way fridge can not be run on battery when parked,it does not cycle so it is like leaving the headlights on in relation to the power consumed, & dont work very well on 12v.
A compresor fridge works like a house hold fridge, it cycles mmeaning it will run till it reaches preset temp & then switch off untill temp rises enough for the thermostate switches it back on for another cycle.
Janno, running a 3 way fridge on 12 volts will use more power than a 2 way running on 12 volts.
You may also find running a 2 or 3 way fridge on 12 volts over lengthy periods and recharghing through solar panels, can actually boil your expensive batteries.
Using gas on a 3 way is the best way to go when no plug in is available, I have a Dometic 90 litre fridge, a 4kg gas cylinder lasts 7/9 days depending on temperature.
A common cause of fridge failure is parking on uneven ground, I had this problem a few times. So chock up and level up first.
Thanks everyone for the info re the difference between 2 way and 3 way. I feel much more informed now.
Even when dead level my fridge won't work, so hopefully tomorrow it will be fixed. If it continues to give me trouble
I will think seriously about getting a 2 way.
For some reason I thought we were on a primus but now I see its not so my post is irrelevent the the post .
