We live on a boat in France. Last year while plugged in to shore power, there was an electrical surge which tripped our on-board main fuse switch and everythig seemed to be fine after re-setting including our fridge with the green light showing power on. The next day, however, we found that the fridge was no longer cooling. We switched to gas and it started working again.
Which parts are likely to be the problem and how can they be fixed?

Re: Fridge not working on 12V or 220V
Hi simon, i would say your ac heater is gone bad. it could have open up and no longer heating when you have a power surge . these heating elemenent are also located in the gas generator. you have to replace this heating element.

I would be checking the main breakers on the panel to insure one didnt trip when you added generator electric. is there a breaker on the outside line at the box you may be missing? Also keep in mind, although uncommon, breakers do BREAK and need replacing. are you competent enough to use a volt meter to check the hot leads on the box and at your unit breaker box to insure you are getting power into the unit? In some older units the switch between land power and generator power was to manually throw breaker switches but automatic processors have replace them now... I would say start at the residential plug in and verify power is where it should be along the route of the supply cord...from the meter forward... if you have a converter plug, say from the 220V 30 amp that you are probably drawing down to 110V household, stick that on the meter and plug in your toaster to insure there is power coming in....IF YOU DONT HAVE A METER AVAILABLE... otherwise...test test test... your generator probably broke a circuit somewhere... now just to find it..
Ez test to determine if stator wiring is ok. This test works on generators that have two sets of 115v plugs and 220v plug. Use a 12v, 1amp ac power supply ( smaller ac power supply should work ok ). With generator not running, apply 12v to one of the 115v outlet plugs. Now verify 12v output voltage with meter at another 115v outlet on generator. Also verify that there is about twice the voltage at the 220 v outlet plug (should be about 20v - 24v) . If the adjoining 115 v outlet plug has no output or very little voltage or if the 220 volt plug has no output, most likely stator is damaged or breaker is off. If the stator is shorted voltage reading will be very low and power supply will heat up. If stator is open, there will be no voltage at second 115v plug or 220 v plug. If voltage is ok at the other outlet plugs as per test above then most likely problem is with voltage regulator, or brushes not making contact or armature winding open or just needs to be energized. Unplug the 12v power supply after test to prevent it from overheating. Most generators have two 115v windings that together power the 220v plug. When you energize one of the windings with the 12v power supply, the second 115v winding will be energized also and give you a voltage reading about equal to 12v. You will not damage the generator with this small voltage being input thru the plug. Good luck
You might unhook the battery and with the camper plugged in to shore power the 12v lights should work. If not check the breaker that goes to the inverter. If that is not tripped then check the power output at the converter. I would expect the inverter is shot. I replaced the one on my Jaco two years ago with (Progressive Dynamics 60 Amp Power Converter with Charge Wizard and the remote pendant)
Not by plugging it in direct!
You will need a transformer, or a more modern equivalent 'box' which will take the 220v supply you
have now and drop it down to 110V.
Try your local hardware or electrical store or look in your telephone directory under 'electrics'- hopefully you should find one from one of them ;-0)
Most likely reason for 'ticking' sound is one or more FET(field effect transistor) have shorted . Any electronics shop can fix ,but, repair may approach cost of replacing . The parts themselves are not expensive but labour may be high .
Consider getting an inverter designed for solar installs with proper automatic 'shore power' switching and never worry again .
if this is a new problem that suddenly occurred, then trust the fuse box...the frig has a problem. Most likely a compressor motor that has been electrically damaged...could have been power surges from utility or lightening or unknown. It also could be a wiring problem in the house...mice have been known to chew through wire insulation...they feel the warm wires and are fooled into believing the wire is a live food source and start chewing. A test of this wire problem is to remove the frig and plug in something that will demand close to the same current...(should also contain a motor)...read the frig's label on back of unit.
