    Default Engel fridge not working

    My standard fit Engel Fairline galley has stopped working. The light comes on so it's got power but the compressor isn't starting. Any ideas? Knackered thermostat?

    Are those fridges dual 220/ 12 v in your case ?
    Reason
    If so the switch thingy which is automatic and prioritises mains might be knackered .So itís actually running on 12 v .House batts it may have a dead batt / flattening protector , which cuts the comp below a certain batt V in order to protect them
    Light comes on but comp is off .

    To diagnose ^^^
    Gets a bit tricky, you basically need to isolate every bat load , ie switch off if shore bound and let the charger attempt to recharge the house batts ,or go for a long run on the engines .

    Thereís another sinister reason ......
    Chargers decaying
    They just donít pack up right a light bulb they slowly decay in terms of output .You just assume they are not kicking out much because they donít have the demand , but all the time the house batts on shorepower are depleting until below fridge voltage comp cut out .The V regulator may have been knackered a while and the fridge running on house batts masked this .

    We had the identical issue a fridge with light on but seemingly no comp .Intermittent.
    It turned on with a run out - alternators , for a while , seemed on immediately after hooking up in a marina then switched off
    .Turned out the 40 ah charger was only giving out 4 ah max , so unable to keep the house batts tops up with normal marina usage , hence the fridge felt it first .
    So
    Faulty 220/bat controller - take boat for a long run .
    Faulty charger - ditto
    Weak house bats - struggling to hold charge - test them with a basic voltmeter I think you are looking for over 12.7 ?
    Our boat sparky did the diagnostics.Replaced the fridge V regulator and the charger - bigger 80 ah after he did some calcs .

    Once all this tests through, go shopping for a new fridge .

    Fingers crossed its just a corroded connection on the back of the control box on the fridge.
    Pull the fridge out of its' housing so you cab get at it - unplug/isolate the mains supply to it first.
    On the control box there are usually about six connections, +12v 0v, 240v 240V, thermostat 1&2, fan (if fitted) possibly a couple more. They can get covered in condensation etc and the connections rot away.

    With a multimeter first measure the +12v supply -usually the fat red and black pair of wires disappearing back into the boat. Should be the same as the boat battery voltage. If it's within 0.25V that's fine otherwise could be a dodgy connection at the circuit breaker end. Go check that out.

    If the 12v supply is OK carefully pull off the push on connectors one at time and examine them - fingers crossed one or more of them has failed. If you can identify the thermostat connections (2 thin wires) disconnect them both and use your multimeter to measure continuity through the thermostat as you operate the thermostat. The thermostats are just bi-metallic switches. When its closed (on) you should see 0 ohms, open (off) infinite ohms.

    If all the connections are OK and the thermostat is OK its either the compressor or the control box. Its possible to measure the output voltage to the compressor but I can't remember exactly what it is (24v AC?) - set the multimeter to 250 AC volts and see what's coming out when the thermostat is on (closed) and the +12v DC supply is on.

    good luck

    if you have the wiring diagram you can link across thermo terminals to check out if duff, Make sure it is switched to on to test!

    Turn off 240 and see if it works

    Mine only works on 24v supply as the change over for the 240 is dead ( turn on 240 and it stops working) . This cause no practical issue and changing the module is all but impossible given its location

    The odds are it is the same fridge
