Most driers have to be disassembled from the back and work your way forward. Try that.

I do not know your system but It sounds like a restriction forming in the system. It may be calcium deposits or a valve not closing properly.

call an assistance to your technician...

A power surge has occurred unfortunately. this surge has fried the control module and, you will need to replace this module asap.

I would check the motor as well. it may have took a hit as well. test the continuity of the element as well.

Looks like the printers internal electrical components have gone. if there is a tranformer in your printer then that is making that noise. or else even the motors might also be gone.

my strong suggestion take it to any authorized service personnel

Hi, There are usually 1 or 2 fans inside the TV's. Could be worn bearings, or fan blade interference. Sorry, without my electric ear working, I can only guess.

The power surge has caused a failure of an internal component. If it is making this noise it is possible the line output transistor has failed. I would advise calling a service repair centre & have someone there take alook at it. All being well this may be the only problem. Power surges can sometimes cause other faults.
