I am replacing the synchronous motor in this tower fan model and have found a suitable replacement. However, the original motor has a white plastic arm attached to the motor by way of a hollow metal pin running perpendicular to the motor shaft.

How is this white plastic arm removed or where can I get a replacement?

Portable Air Conditioners: How to Disassemble Sharp Air Cooler PJ-A200TV-B? Pump Replacement

Wed, 04 Mar 2026 19:03:48 -0700

I own a Sharp air cooler (PJ-A200TV-B) and the water pump has failed, most likely due to our Malaysian water quality causing mineral buildup over time. The fan still works fine, but without the pump circulating water, it’s basically just blowing normal air.

I’ve removed every screw I can find on the unit, including the obvious ones at the back and bottom, but I still can’t fully dismantle it. It honestly feels like this thing was designed never to be opened. I don’t want to force it and risk cracking the plastic clips or damaging the casing.

Another reason I need to take it apart is to properly clean the internal fan, as there’s quite a bit of dust buildup inside. I can only clean the exterior and filters, but the fan blades themselves are hard to reach without opening the unit.

I’ve searched online for a teardown guide or tutorial video but couldn’t find anything specific to this model. I did find a Facebook post from someone who replaced the pump before, but he hasn’t responded to my message. Maybe he’s no longer active.

I’ve already sourced a compatible replacement pump from Shopee, so I’m ready to fix it myself. I just need guidance on how to properly open the unit and access the pump without breaking anything.

If anyone here owns the same model or has experience taking apart Sharp air coolers, I’d really appreciate any advice, photos, or step-by-step tips. Thanks in advance.
