bjphillips Posted April 23, 2007 Share Posted April 23, 2007 My fridge in my Laika does'nt appear to be getting very cold when on the 12 volt system,any suggestions what it could be or is it a workshop job for the experts. If so who's the nearest to spalding who tackles this type of problem ? :D Link to comment Share on other sites More sharing options...
Guest JudgeMental Posted April 23, 2007 Share Posted April 23, 2007 If a 3 way - gas/230v/12v fridge? the 12v side is for when travelling and I believe has no thermostatic control? if a 12v compressor model sorry Xspurt help required :-D Link to comment Share on other sites More sharing options...
Clive Posted April 23, 2007 Share Posted April 23, 2007 If its a normal absorbtion type (Dometic or Thetford) then firstly confirm that the light comes on the fridge front when the engine is running. If this is confirmed then perhaps the 12 volt element may be deficient. As has already been pointed out there is no thermostat in circuit for 12 volt operation. If you measure the current taken expect something between 8 and 18 amperes depending on the size of fridge. If you have no visible indication that the fridge is operational when the engine is running then its time for some fault finding. This sketch may help.

On the point of thermostatic control while on 12V supply, Dometic claim their current MES and AES fridges are so controlled. Earlier ones, and the basic model of each size, are not so controlled. However, I believe the stat is shared between 12V and 240V supplies, so doubt the stat is the culprit. Check operation of the 12V supply relay?
