Lawrence Smith Posted May 5 Share Posted May 5 Todd have you ra this fan with a kilowatt or other measuring device connected? the emerson fans will run the correct way in 2 of the 6 combo's one way is wrong & causes heat & too much amp draw. your fan should run under 1 amp on high speed at line voltage. for a guideline , I would test this before sending off the speed coil.

Lawrence, thanks for the tip! I unearthed the Kilawatt device I had, and plugged the fan into that. On all three speeds, it’s drawing approximately 1.65 amps; isn’t the amp draw supposed to be different on each speed? I copied the wiring layout the way it was before I messed with the wires.

Roger Borg Posted May 5 Share Posted May 5 Have you checked all connections at the coil? I imagine if there's a bad solder connection, it could be causing extra resistance?? Quote Link to comment Share on other sites More sharing options...
Lawrence Smith Posted May 5 Share Posted May 5 You need to trace your wiring, that’s too high amp draw . Quote Link to comment Share on other sites More sharing options...
Todd Adornato Posted May 5 Author Share Posted May 5 I pulled the switch out of a running 29646 and wired it up to the 19666, and let it run on Hi for about half an hour so far. The steel plates around the coil are lukewarm to the touch, and the Killawatt amp readout on Low is 1.10, on Med is 1.17, and on Hi is 1.48. Will the readouts normally be higher using the 29646 switch as opposed to the 19666 switch? The cycles rating shown on the 19666’s motor tag is 58, and it’s 60 on the 29646.

The red coating on the top of the coil made a mess and is sunken into the wiring, so it’s going to be tough to trace the wiring without removing the stuff. It also stinks when current is passed through the switch, so at this point I’m leaning toward sending the switch out for a rebuild. All the advice given so far is much appreciated!

The steel plates around the coil are lukewarm When you run the fan on high you're bypassing the coil's purpose to slow the fan. High speed is full wall current. Test the coil on low speed up to 1/2 hour checking the coil/laminations for overheating frequently. Edited May 5 by Russ Huber Quote Link to comment Share on other sites More sharing options...

Check your 19666 tag again to see if the number 58 is stamped for WATTS, not cycles. Your 29646 motor tag will not sport a wattage stamping. Below is my quote made on the first page of this post. I was in my stash today and peeked at a 21666 and 19666 12" 6-pole BIG motor types. Both had 65 Watts stamped in the motor tag. I then checked two 12" 4-pole small motor 24646 models that had wattage stampings in the tags. One was 60 watts and the other 64 watts. There you go. It would be logical the 21646, 27646, 29646, 73646, etc. 12" small motor 4 pole type numbers either oscillating or stationary types would be operating at similar wattage as the 24646 models. ~ Russ Huber Quote Link to comment Share on other sites More sharing options...
Todd Adornato Posted May 5 Author Share Posted May 5 My bad, the 19666’s tag does state “Watts.” I let the fan run for a half hour on low using the 29646 switch, and the plates got hot to the touch, though I could still keep my fingers in them. The coil was a bit cooler, though the black insulation was starting to come off on my fingers. Probably not the way I want to go with this fan 😉 Quote Link to comment Share on other sites More sharing options...

Probably not the way I want to go with this fan 😉 The coil is going to get warm running on low speed with a rewind or a 29646-cheater coil. My advice to you before you get a rewind is think about becoming a member, I have seen you post more than once. Number two, as a member you can meet up with another member in your area that may have more experience to help check your fan out thoroughly. It would be a bummer to have a coil rewind and have the same problem. Good luck. Edited May 5 by Russ Huber 1 Quote Link to comment Share on other sites More sharing options...

I mentioned the readings earlier in this thread: 148, 137, and 11 ohms. I thought the middle reading was too far from the halfway point between the other two, but I’m assured the readings are perfect. Quote Link to comment Share on other sites More sharing options...

The 2 lowest readings added together equal the highest reading. 11+137=148 Quote Link to comment Share on other sites More sharing options...

I had envisioned “hi medium low” to have ohm readings more or less equidistant from the center. Quote Link to comment Share on other sites More sharing options...

The wires are for the start winding, run winding, and a common. 1 Quote Link to comment Share on other sites More sharing options...
