Blowing Fuses 12V Coleman Thermoelectric

Cut the wires as attach it to ur inverter wires or run it to another fused system. Ended up having to do this as mine kept blowing fuses and melting the plug. Its worked like a champ sense then that was 2 years ago. I added a toggle on off switch to the setup also.

Cooler ended up dieing here a few months ago and ended up getting a factory fridge.

 

It's the Truck lol.

I used to Slipseat
The Truck I originally had the Cable didn't get hot and melt the plug all the time.
On some of the Trucks the cable/plug had a tendency to get HOT really hot and eventually melt, as well as blow the fuses.

So..Not sure why/how but for me it only seemed to happen on some.

 

Try a new plug/wire assembly, and maybe a different socket.

This is just a fact of life with these 12v coolers.
I try to use a plug that has an led on it so I can look over and see its still running. I've even added an led to a few of the coolers I've had.
Too often they blew a fuse or died and I didn't notice for hours. Food got warm.
If you hit a big electronics store like frys you can even find a 12v fan that has some leds built in, for less than ten bucks. These are for pc case fans for gamer types, but you can usually find one that will fit and work.

 

Maybe the replacement fan they sent you is defective? To me, that's not hard at all to consider as a possibility.

 

I'm not an electronic expert, but I had the Coleman 40oz cooler and the fuse burned out and melted inside the adapter.
I said screw it and bought an Igloo 40oz Iceless cooler a few months agao and it's been working fine. It's only about $100 if you just want a less expensive one. I haven't been able to invest alot of money in one of those $600 coolers yet, maybe one day. They must be ###### costing that much.

 

When a fuse blows,it is caused by drawing to many amps not a voltage spike. The fuse is a safety device for your protection. It prevents really expensive damage to circuit components. Replacing a fuse with a much higher amp fuse can lead to an electrical fire. If a fuse keeps blowing there is an electrical problem with the unit that needs to be fixed.

 

Glad to see I'm not the only one who had trouble with melted plugs on these coolers.

I finally cut the wire close to the cooling mechanism, used 12ga wire, put, an "eye" end on both power and ground wires and hooked them to their respective studs on my inverter, coming off battery. Used 20 amp inline fuse at the inverter stud.


Been working fine for 4 mo now.

 

I have removed all the cig plugs from my burton stove and igloo cooler and went to Anderson power poles .
I have a power source right from the batteries ( fused of course) with the power pole connector on it both work better since the switch and no more hot plugs !
I am in the process of upgrading the fans on the cooler as I type this so it should do a better job of moving the air inside and out !

 

One thing I found after I melted the an inverter plug a few times. Take a cable tie or a plastic fork tong and slide between the plug and the connector. Sometimes the plug will slide out a hair or two and have an "air gap", causing it to draw more current. Hence the melted plug syndrome.
