JANDY LXI250N blower won’t start

[matiusmatt]

Strange problem. Blower motor gives a little turn along with the humming sound, then stops. Maybe 20 seconds later it tries again. I can see the blower start to turn a bit. I changed the capacitor in hopes that was the problem but no luck.

Below is a link to the start up

Any advice is appreciated.

Sounds like a bad motor. Can you turn the blower wheel by hand?

I can turn it by hand. Turns quite well. Last week it even started up. Then ran and even started up a few times after that. I experienced the same end of last season.

When it was running the blower casing was too hot to touch which seemed a bit strange to me.

Under normal conditions, most motors run too hot to touch for long, especially inside a pool heater.
The only way to truly tell what the issue is is to isolate the fan connection and see if voltage is being sent to the motor. If so, bad fan. That's what it sounds like from 3000 miles away.

Many thanks for you replies.

I’ve just purchased a multimeter. Have done a few basic tests around the house but not sure how to approach this. Attached a wiring diagram of the motor (or you can see the full on page 24 https://www.royalswimmingpools.com/JandyLXiManual.pdf) Any idea what I should be testing?

Secondly, is it practical to have these motors repaired? Surprisingly I do have an electric engine repair shop just down the road.

Update: it was the blower. Had a technician come in and check it and there was power to the motor but no action. Now replacing the blower.
