What is the right type of MOV converter capacitor as it blowed up?

I bought Keurig K- Elite from Costco and took back to Singapore. The converter capacitor/ varistor blowed up with mistakenly plugging 220v directly.

Can anyone help advise on the replacement part number as no clear marks can be distinguished from this burned one? Thanks.

BTW. I already bought a 110-220V converter to be ready after Keurig fix.

Answer this question I have this problem too

Is this a good question?

Hi,

What are the voltage (V) and power (W) specifications as printed on the model label on the machine?

This will help to determine what value MOV is required.

What is the full "board" number of the board in your pictures? I can only make out 2628 Rev A.

Maybe searching for the "board number" online may give results. Worth a try anyway.

Also hopefully you meant a 220V -110V converter?

Thanks. The spec of the model is 120V 60Hz and 1470W

The board number is PT0000002628 REV A . Which unfortunately I can not Google out anything.

Yes the converter is 220-110.

The part number you need is Littelfuse Inc. / V150LA5P . I had the same problem and I was able to get info off of my cooked varistor. I used #3 helper glasses, a clip on #4 magnifier, and a magnifying glass to read most of the numbers. I was able to find my part at Digi-Key parts on line. The part is 60 cents and shipping was 5 bucks. Hope this helps you.

Hi,

I couldn’t find any information about your coffee maker and I’m not a circuit designer but I think that this MOV -example only would suffice.

It has an AC cutoff rating of 150VAC which is about 20% higher (which is usually what is specified for MOVs) than the supply voltage of 120VAC. It also has a current rating of 25A so if it does operate to suppress any surges it will be able to handle enough current for a short while anyway before it fails. Your machine only uses 15A but I thought that getting a MOV with a current value of 15A was cutting it a bit fine and the next value is 25A.

Unfortunately I cannot find a supplier that supplies less than 5 pieces. You may have better luck. Alternatively go to your local electronics parts store (or electrical parts store) and ask for a MOV that has the specifications of 150VAC, 200VDC and 25A and that will fit on the board.

Also be aware that there may be more problems with your coffee maker. Hopefully the MOV did its’ job and operated before any damage was done to the other components on the board and not after.

I guess that you will find out.
