In the morning, I repaired a Haier power board and got a strong response from everyone. These units were also ready for repair. In the afternoon, I went to pick up some dry goods. Another Haier power board arrived, which is more classic but was damaged badly and not easy to fix, as shown in the photos. The components C35, C36, and C37 were burnt or cracked, with electric leakage. U1 1377 was damaged, V2 W10NK80Z had a breakdown, and FUSE1 6.3A was open. According to the schematic, C35 and C36 are 102/1KV, and C37 is 472/1KV. I replaced C35 and C36 with 681/3KV capacitors, and C37 with a large reverse capacitor of 4700P. This replacement worked well without needing further changes. These are peak absorption capacitors, so their power rating is sufficient. V2 W10NK80Z was replaced with K2968, and U1 1377 was directly replaced. This made the board functional again.
Let me talk about online shopping again. I usually buy accessories from both physical stores and online platforms. For washing machine parts, I tend to go to local stores, while electronic components are mostly ordered online. It's like finding hidden treasures. From 2008 to now, this is my V4 level experience. I once bought something for someone else and added 10W to the cost. Everyone likes online shopping because it’s cheap, convenient, and easy. My trick is to check the seller’s positive feedback rate—preferably over 99%. A high rating means better reputation and fewer issues, which helps avoid returns and bad experiences. Now, most products are in good condition, and there’s no need to return them within 7 days. That’s consumer protection at its best.
I recently purchased a 681/3KV capacitor from two different sellers. The picture showed a big size, but the actual product was small. I didn’t ask for a refund and left a negative review instead. Just for your reference.
