Broke the 12v DC plug on our Rubbermaid/Vector Thermoelectric cooler. Can't find a specific replacement plug. Any specific specs I need to look for in a replacement?
Re: Broke the 12v DC plug on our Rubbermaid/Vector...
A generic plug should work...just be sure to size the fuse correctly to protect the unit. Most thermoelectric units draw about 4 to 5 amps...so a 10 amp fuse usually works.

Did you accedently or spark power wires? These have a tendency to blow the diode if that happens. Also check fuse in plug of cooler. Take it apart an look sometimes the wires break.
Your Peltier is most likely shot! You can fix it for less than $10 in about 30 minutes.
Take the back of the fridge apart and remove the fan and aluminum heat-sync. Sandwiched in between the heatsync you'll see the Peltier pad with two wires coming off it. That's what you need to replace. The peltier has a make and model number on it. I would recommend ordering the same make and model. The specs should be 12v DC and less than 5amp and 60 watt draw. Your wine cooler's power supply can only output 5amp and 60watt max power. When you install the new Peltier you'll need to spread new thermal compound on both sides of the Peltier. I recommend Artic Silver Ceramique. You can buy this at your local Radio Shack or any computer store where they sell motherboards and CPUs. Ceramique Thermal Compound
You should get the number from the bottom of the cooler and then call Rubbermaid at 888-295-2110 and ask for the replacement part. I'm looking for the same thing, but am away from the product for the number so I was told to call back.
Thermoelectric devices (or modules) require direct current (DC) for operation. Alternating current (AC), the form of electricity found in wall outlets, causes a thermoelectric device to alternate between heating and cooling, rendering it effectively useless. "Ripple" is the AC component of DC current and occurs when a power supply does not completely convert AC current to DC current.
You just might want to find out why the AC is not turning to the DC required, This could be a matter of chaning outlet plug or maybe the Ower pack that coverts the AC to DC.
you should see if theres a DC voltage going to the plate or not. it should noticeably heat up instantly with proper voltage applied. if power is there and it doesnt heat then the thermoelectric device needs to be replaced. also you should be able to measure a resistance of the plate. Should not be shorted or open. it should be a relatively low resistance. like a few ohms. and it may read different depending on which direction you connect the leads.
I think you've actually diagnosed your problem. Get that fan moving and you'll probably make this go away. Rubbermaid has a website and decent customer service. If you're in warranty...go there first.
