ApplianceLinc V2 2456S3 dead, repair advice please?

[adambuild]

Hi all,

I have an old ApplianceLinc that is now dead. Would love to repair it. Tore it down and have a bad Licon capacitor at C2 on the circuit board: 470mfd / 35v. Can anyone please give advice as to what it should be replaced with?

Thanks very much, Adam

I had a few go bad myself. One was On and started to pulse on and off at about a two second cycle. Mine was a green cased NOVER brand cap.

It is not a high frequency supply. It is a half wave circuit. 30 cycles on the cap. Not like what was in the PLM and another few Insteon modules.

I just got a good quality Panasonic 470mfd/35V designed for power supply use. Panasonic EEU-FC1V471 but any good brand should be OK. They where taller but still have room to close the top cover.

This is the Icon version of the V1.4. The V4.? used the same capacitor just a 100% different design. I have used that capacitor in a V4 and my V1 modules. In the V4 it is sideways parallel to the board and has some component glue holding it.

I took another look and the Licon brand was in my 4.? versions.

If it is a 4.? with the cap parallel to the board. You should sill be able to use the original sized 470mfd/35V. I had one of the 30 volt Zener diodes short. Under the cap. I got lucky and replaced it and the cap for good measure.

Since it is around a 30 volt supply. The 35 volt cap should be fine. Depending on size a 50 volt would also work with a larger voltage tolerance but probably a larger size. Longer or fatter depending on what you try to use.

I agree with Brian that Panasonic capacitors are good replacements.  I did see that the model Brian used is out of stock at DigiKey.  I did do a search at DigiKey and they had six ones that had outstanding specs:

One of those parts, Cornell Dubilier / Illinois Capacitor #477KXM035M had a great lifetime rating and a high tolerance to ripple current at 120Hz.  it only cost ~ a buck.
