Testing variable speed blowers

[bmac]

I'm wanting to get a tester for variable speed blowers. Can anyone give me thje scoop on what's available? Is there one that works on everything? Thanks.

Check out www.thedealertoolbox.com for information and such on variable speed motors. They also offer a tester there that works on most, if not all, brands.

I have the GE Tech Mate Pro. Easy to use and I picked it up from Totaline. I have the pdf file you can read about testing those motors but it is to large to post it is 2.4 meg. It is the book that came with the ECM tester. I found it on the internet here

Zebra is the way to go but they have yet to get the Model 13 adapters in to our supplier so the new version motor can be tested.

We bought the zebra. First one we used it on, we needed an adapter that didn't come with it. Just picked up both adapters(had to order) so we'll be ready for the next one. I think they should include the adapters with the kit.

Don't forget to ohm out them motor windings once you seperate the module form the motor.

I've found DOZENS of the G.E. motor windings in the last few years where they like to rub and short together. (Kind of like cap tubes rubbing and leaking in a Goodman Heat Pump). I think quality went down the past few years on them motors

Check them like a 3-phase motor. You should have almost the same ohms from pins 1-2, 1-3, 2-3 and NO continuity to ground.

If the ohms are really low on one pair of pins then the windings rubbed together internally and are shorting form one to another.

I've actually seperated the shorted windings and put a new module on for temp repairs before.

what kind of money are we talking about for the zebra?

[bmac]

I think it was about $180.00?
