Frigidaire intermittent vibrating noise

[iliiinieis]

Frigidaire CRER7900AS1 Dryer. It heats, it dry's and works perectly. The problem is it has this vibrating noise every so often. It just started after 7 years.

So, I bought a Maintenance Kit and replaced the following:

Rear bearing (the metal ball, plastic cup, little ball bearing and new grease)
New belt
New tensioner pulley
New upper and lower felt
1 knob

All of these were worn out so I felt good putting it back together. It spins great! Heats good. still vibrates, its almost a humming vibration and it will start soft, then get really loud and then stop all of a sudden. Movign the dryer seems to have an effect although I can't seem to get any one particular movement to make a difference. I even leveled it out. I watched the heating element to make sure it s not happening only when heating or not heating and there is no pattern. Help! What could it be?

Maybe you have something in the blower housing doing that.

I vacuumed it out. I figured it would be gone if it was in there. I will take that apart tomorrow and look. I thought maybe there was some type of solenoid that was sticking and making the noise. that is what it sounds like. Like the starter solenoid of a 79 Ford F150 351W that is gone bad. lol

My wife has a load of luandry init now and its pretty steady now. Its a loud humming/buzzing. Would a recording of the noise help? Not sure how I will get it but I can try.

Yeah record the sound

Ok, I tried to record it but it won't come across in the recording. Ironically most of the noise is gone now except certain times. Its so weird. When it gets really warmed up it seems to fade. This thing is posessed!

I like to work on them at my shop precisely because of that. I toss my clothes in there and do my laundry. Let that baby go till it smooths out and act all propah.LOL
