Choke coil buzzes loudly when the treadmill is under load
I have a ProForm 2500 (PFTL49720). You can't hear the choke coil unless you get on the treadmill. It then starts buzzing very loud. The treadmill does not bog down under load and keeps a constant speed. I have taken the choke out of the wiring and everything ran fine. Do I need the choke? Does the loud buzzing indicate it needs to be replaced? Can it be tested?

I would recommend that you replace the choke part# 185582 and also to lube the belt.
