Hello,

I have an Engel fridge that no longer work's on 240v. I lent it to a family member who had it running of a geny. Apparently something went wrong with the generator and it put out to much voltage.

Now the fridge doesn't work with 240v, it doesn't however work really well on 12v.

Does the fridge have some kind of internal fuse? Any ideas what damage might of been done?

Many Thanks!

Perhaps the person who borrowed it might be able to fix it.....

As for joc. Ask the "borrower" to get it fixed.

Shame. Every time I lend something my wife kicks me. Now you know why.

Chris,

There is an in-line fuse in the 240 volt patch lead that may have blown, although if it no longer works very well on 12 volts, something else has probably "cooked".

If the fuse did not protect the circuit then the damage ought to have stopped at the inbuilt inverter. If twelve volts is running the heat pump then it may be a thermostat problem too though you dont say what sort of problem with the 12 volt side.

In the instructions Engel specifically say NOT to run it directly from a Generator but to charge a battery with the gene and run the Engel from the battery.

My guess is that the inverter board that switches from 240 to 24 and from 12 to 24 is damaged.
Labour costs being what they are it probably needs a new inverter pack.

My question qwould be "Did you tell the borrower not to run it from a generator?" If yes he should pay, if no it is hard earned experience.

Thanks for your replies.

It should of read "It does however work really well on 12v"

I really shouldn't write things that late at night!

Probably about 6 years ago Engel released their new fridges with a sticker on them declaring "Generator compatible" this,as I found out from Engel was a ploy to equal the same statement from a rival company who were stealing sales off Engel. Subsequently people went out and bought the $99 GMC genny's to run their Engels...the generators being 2 stroke & not sine wave inverted caused damage to the fridge motors due to current spiking etc...this is the info I received from an Engel Tech when I phoned up Engel in 2004...he told me NOT...NEVER run an Engel off a 2 stroke Generator or straight off any other form without it being sine wave equiped. SO. If I were you I would phone Engel & organise repair of fridge. What you do with your equipment is your business. I never lend anything like chainsaw,Engels, mowers or my cars to my adult children because if they break them they have not got the $$$ to pay for the repairs. So endeth the lesson!!

2Stroke gennys defininitly are sine wave. Always run with a 100w globe & make sure engine Rpm is correct. Never had any trouble running Waeco fridge or switchmode chargers of GMC 2 stroke genny. Daryl

OREJAP,
That's interesting, the Engel tech effectively told you not to run an Engel fridge off an Engel generator!

The Engel generator is a square wave output and it's stated as such on their website if you are prepared to dig right down into the fine print!

The fridge should be run direct off the battery. The battery can then be charged by a proper battery charger powered by the generator.

dbish (Daryl): Orejap mentions sine wave output; also the voltage level is important, whether the wave pattern is a sine wave or not; also, the frequency is important, whether the wave pattern is a sine wave or not.
I have checked the GMC website after reading your comment: GMC make no claim about their 650 and 750kw gennies being sine wave, they specifically say these models do not have AVR (automatic voltage regulation) and they make no mention of the frequency control parameters. GMC say you should not use these models for 'sensitive electronic equipment'.
You may be right that SOME 2 stroke gennies have a sine wave output (Scorpion claim this), and SOME 4 stroke gennies may have a sine wave output.
But the sad reality is that a large proportion of gennies on the market do not have a sine wave output, do not have proper voltage controls and do not have proper frequency control.

Geoff, I am aware that the Engel is a square wave & also the motor is supplied by Honda Japan. The first reason I would never buy an Engel Genny. I am only relating my conversation with the Engel Tech approximately 6 years ago. I always charge my battery in camper via a Projecta 15amp via the Genny. I run my fridge off the battery. FYI.

From memory i think there is a fuse on the 240 board that might be worth a check. They arent real hard to pull out to check. Cheers marn

There is a double pole relay in the power supply module of the fridge, it is used to change over from 12/24 to 240 volts. This may be your problem.

I guess the first thing i would do is try and confirm the power cord isnt stuffed

Thank you for all the replies.

To provide some feedback.

I found a company in WA that could supply me with a replacement power supply for about $300.

Apparently there is an on board fuse however it is soldered on and to remove the board from the power supply requires more tools than I have.

I have taken the power supply to a local appliance repairer to see if they can fix it.

Thanks again.
