Topic: Buzzing/Chirping from Power Supply

Does anybody else's power supply make a little buzzing/chirping sound when the printer is running? Mine makes a very faint sound intermittently while printing, like a tiny cricket inside. It sounds like a bad sound for a power supply to be making.

Re: Buzzing/Chirping from Power Supply

I don't know if its bad but it's not uncommon.  I can hear faint hums, chirps, and pops from most electronics or their power supplies.  The thing that bothers me is that the power supply gets incredibly hot.

Re: Buzzing/Chirping from Power Supply

My SD4 power supply does it all the time.  Its pretty annoying.  I'll probably buy a new power supply.  it sounds like the internal fan is failing on mine.

Re: Buzzing/Chirping from Power Supply

Ummm that sounds like a loose connection is arcing. This is not only really bad for the hardware in your machine but it's also a serious fire hazard! Increased resistance means increased heat!! You should replace your power supply immediately before it causes a fire or shocks the hell out of you.
