How to repair a Motor Control Unit for a Whirlpool Washing Machine

My scenario pretty much the same. Those 3 green resistors. Anywhere to order them or a substitute maybe? Seems a lot I do find they want you to buy them by the thousands. I found one same specs, but it turned out to be some tiny one like maybe goes in a cell phone, watch, etc.. And that one was $10 I had to eat.. lol .. Thanks in advance..

If you read above, @schnittker gave a Digikey part number:  Digikey VMP-R050-1.0-U, 50 mΩ, 3W resistor, $1.73 each

I also found a similar resistor at Mouser, but a lower power:  Mouser TLRP2H20WR050FTE, 50 mΩ, 2W resistor, $0.74 each

Hi,

Did you find the correct chip? I have the same chip burned on my board. Thanks.

The main chip that often blows is Power Integrations LNK304GN. I replaced with LNK304GN-TL. Digikey 596-1022-1-ND

The three sense resistors that often blow are 0.05Ohms size 5025. I replaced with Isabellenhuette VMP-R050-1.0-U  Digikey 4423-VMP-R050-1.0-UCT-ND

The little resistor next to the switch is a size 3216 labeled 1R00 which is 1Ohm. I used Vishay CRCW12061R00FKEAHP Digikey 541-1.00UCT-ND

Thank you so much for the links to digikey. That made finding parts way easier. I was curious about the capacitor next to the sense resistors. I think mine has been damaged, but when I pulled it off my board and measured the capacitance, it measured .23nF. I can't find a 500uF cap anywhere. Do you happen to have the part number for that one, too? Thanks again.
