Powered the machine in wrong voltage
How to repair the machine if i plug the machine in 220v?
Hi @tom97 ,
That’s a MOV (metal oxide varister) or surge suppressor if you like. (the board designation for the component is MOV1). It protects the equipment from overcurrent situations by shunting it away, but if you apply too much voltage (assume you plugged 240V into it) then it will blow as this is too much
The hard part will be to get the correct value replacement.
Maybe try very gently to see if there are any component markings left on the side of the MOV closest to the C14 capacitor that it is next to. Do not touch it with your fingers as sometimes they rub off easily.
If there is nothing left then here’s a link that may help to get you out of trouble. You could try the MOVs as suggested and see how it goes. Hopefully there is nothing else amiss and it is only the MOV that failed
It’s just a matter of unsoldering and removing the old and soldering in the new. They are not polarity dependent. The worst that could happen is that it blows again but I assume that you will have the coffee maker connected to the power via a suitable step down transformer this time ;-)
What is the model number of the coffee maker?
Hopefully you have only blown a surge suppressor and a fuse on the circuit board.
You will have to open the coffee maker and inspect the circuit board for any obvious damage to the components.
You don’t state the model number so here’s a link to some of the ifixit Keurig Coffee Maker Repair which may help if your model is amongst them.
If there is damage or even if you’re not sure post some close up pictures of the circuit board where the power is connected to (both sides of the board if possible - take pictures of the connections before removing the board from the device so you know how to reconnect it).
Here’s how to do this. 在已经存在的问题里加入图片
Also do you have a DMM (digital multimeter) and know how to use it?
