Hello everyone. I have a Jandy LT heater on my pool. I recently replaced an ignitor and flame sensor, which fixed one problem thanks to this website.
This was the first time I had turned the heater on in a few months. Once it came on and the gas ignited, I noticed a loud vibration when the exhaust fan was engaged.
I suspect it is simply the fan bearings are beginning to go, but could there be another cause? I read something online about a switch of sorts causing similar problems so thought I would check with the experts. The vibrations occur only when the fan is going.
Thanks in advance.
