Seeking advice on replacing a capacitor to the compressor in an dehumidifier. The capacitor in question is a CBB61 3 wire 7uF 450V one, made New Tech. It is also rated at 50/60Hz
I have searched all over the internet to try to find one which is of the same ratings, with 3 wires to allow for a straight swap, however 3 wire capacitors do not seem that common, especially at the above values. I am instead now looking to swap it for a 4 wire capacitor or 2 wire capacitor and was hoping for some advice on how to go about doing this. The capacitor has one wire from the dehumidifier’s main board which connects into it. 2 wires, a red and white then lead away from the capacitor to connect to the compressor. Any advice would be greatly appreciated! thanks in advance J. Edit: Extra photos of the ID sticker of EasyHome dehumidifier and the capcitor at a different angle
Hi @vishsapa, Having the circuit really helps. If you have an Ohmmeter, disconnect the two red wires from the 7uF capacitor and then measure across the two terminals where the reds were connected on the capacitor. I believe they’re the same point and you should read a short circuit between them The circuit shows a red wire into the capacitor and then a red wire from the same point on the capacitor into the compressor but obviously in reality the red wire runs from a different terminal connector, but is the same point. Here’s a supplier -example only of what you need. Just connect the two red wires to one end (they should be the same point in the capacitor) and the white wire to the other end leaving the terminal next to the white wire spare. There may be other suppliers that suit you better. Just search for CBBI 61 7uF 450V capacitor to get results. The only other CBBI 61 7uF capacitors that I found have wires coming from them and not quick connect terminal connectors which would mean that you would have to solder the two red wires to the wire at one end and the white wire to the wire at the other end. If you decide to do this then use heatshrink tubing to cover the soldered connection to provide good electrical insulation as electrician’s tape can come undone after prolonged use.
@vishsapa there would most likely not be a ground to a plastic case and a plastic mounting base. We really need to see the whole capacitor. A third wire is unusual and we really would need to see all of your cap. I would go and use a capacitor like this to make it work.
