when i bypassed the thermal fuse, it started turning on. I haven’t tried the 15 min, 1 hr test yet to see if it heats up. once i get the replacement part, i wonder if i will be able to repack it in that compact space !
Its a 3-speed switch. With switch in any of the on position, it does not show any resistance reading in the multimeter across the plug pins whereas my other working fans show a value of about 185-190 Ohms.
Thanks. I will go through the above suggestions. Just to answer the question - yes, its my fan(not curb find). It has been running slowly for years but here in California, we don't need to use the fan, so wasn't bothered other than cleaning the dust and trying. (My other fans which were slow...
Cleaned up the front and back of the bearings, put some 3-1-one machine oil drops, gave a good spin. Assembled it back. Tried with new capacitor, original capacitor or lastly bridging out capacitors. Nothing helped. No movement, no sound. I checked the new capacitor in the new capacitance...
I just bought a multimeter kit for $ 30 a week ago or so...and it does not have capacitance testing...Since I am within the return window, i think I will swap it out to the one with capacitance (whether I need it for this project or not).
I will re-check the shaft rotation. In my first round of testing, I felt it was smooth. If the bearings jam up, wouldn't I hear a humming sound ? Also, is it safe to short the wires cut off from the capacitor (for testing) ?
I have never repaired a fan but thought let me try. I thought the capacitor may have gone bad as the fan was running slowly and eventually completely stopped working. No humming noise.
It had 5.5 uF 250VAC. Got a new one 5 uF 250VAC. Tested new capacitor for continuity test, didn't hear a beep...
