1) Kemet 5% 1uF plasic Can cap ( i think this will fit on the other side of the motor, just above the relays)

2) Kemet 5% 3.5uF Metal Can cap. This will go where the original went

3) Kemet 0.22uF 100Ohm RC networks. Will replace all 4, BUT all 4x have had their wires cut in my unit.. ??

4) There are a large 0.1uF and 0.5uF black caps that are split open, will replace these.

Not thouching anything else..

See data sheets if any body else wants to try these AFTER i test it..ha
4) were cut because EVERY Rifa/Evox/Kemet molded paper capacitor is more or less defective out of the factory gate and will fail sooner or later, so this would have been a known problem with a previous repairman having prevented it in the most lazy way.

Make sure to replace 3) and 4) with polypropylene equivalents where possible. Especially boycot Kemet molded paper capacitors. They should have ended production of those 30 to 40 years ago when better products became available. Do a forum search on Rifa for more information.

The replacement types you found for 1) and 2) look allright to me.
