These fans are hardy but they can still fail. After running nearly 24/7 for 10 years it blow a fuse and my home has not electricity for 2 hours.
Thankfully Mel was resourceful in keeping the kids occupied on a Sunday night while waiting for TNB repairmen to arrive.
Getting replacement fan was another tough one. First having to determine the model, then a Shopee seller didn’t send out till I had to request for refund and switch seller.
Lastly the wiring was tricky. Thankfully I took snapshots before I disconnect, so I can just follow the wiring after that.
