PROTECTOR (FAN) error message - what next?

Hi, I have limited tech knowledge, but my unit is displaying the above error message when I turn it on. I am unable to use it. This is a US model but I live in the UK which means I can't get it repaired by a Sony dealer. Instead I'm looking for some advice that will allow me to ascertain the seriousness of the problem and whether it will be cost effecient to get it fixed. Many thanks! James.

    I have the same problem, but after a year, it seems that there may not be a solution available on this site. If you do actually have a solution, please forward it to I have done nothing to resolve the problem because I have no advice about the nature of the problem. All I can tell you is that nothing works when I get this message and it does not go away.

Look inside the unit. There is a fuse you can replace in the rightmost front of the unit. 125v 3.25A, I believe.

Turn the product power off, wait at least 30 seconds, and then turn the product power on and wait for it to initialize.

Drum will not spin

While most Samsung dryer component failures will generate a trouble message on the display, a failure of the hi-limit thermal protector won't. If the hi-limit thermal protector has opened, it directly interrupts power to the drum motor. As a result, you can start a cycle using the buttons, the 'brain' will turn on the relays controlling the motor ( the faint clicking sound ) and run the cycle timer, but the motor can't actually run. And without drum rotation being sensed, the burner won't turn on either.
Solution is to replace the hi-limit thermal cutout, which is located on the 'nose' of the blower assembly next to the dryer temperature control thermistor ( which is slightly larger than the hi-limit thermal cutout ).
Also note that the usual cause of a hi-limit thermal cutout failure ( or a thermistor failure ) is ducts restricted by lint ... both the burner exhaust duct as well as the blower intake duct. Both should be disassembled and thoroughly cleaned while you have the dryer apart.

Waher shows c1 what is my problem

Error code C1 indicates problem with drive motor-thermal protector-or motor controller
Overloading may also cause the problem.
Press( stop/cancel) to clear the display.
If that does not help then, "C1 = Average current limit Or Instantaneous current limit."
If a status signal comes back from the motor controller that a current
limit has been breached, the unit will return to standby mode and
display either CA for average current limit trip or Cl for
instantaneous current limit trip.
Average current trip occurs if there is a 2 second average of current
draw greater than 5.55 amps at the motor windings
Instantaneous current trip occurs if there is a spike of 26 amps
instantly at the motor windings.
This may signify problems with the drive motor, thermal protector, or motor controller. Over-loading the unit may cause this problem.

I have a ca code what does this mean


Thanks for using FixYa. Error code CA means Average current limit. This error code will display if the load of clothes is more then the normal load. Also if current limit breaches then status signal comes back from the motor controller. The unit will return to standby mode and display CA. Average current trip occurs if the current draw at the motor windings is greater than 5.55 amps in 2 seconds. This error occurs if there is a problem with the drive motor, thermal protector or motor controller. Over-loading the unit may cause this problem.

Please do rate the solution and revert for further assistance.

Error code - protector

Try disconnecting all the speakers from the back and turn the unit back on. If the "protector" display goes away, turn the unit back off and reconnect one speaker. Turn it back on and check for "protector". Repeat.

If you find that one of the speakers causes "protector" to appear, you either have a bad speaker cable or bad speaker. Try swapping each of those out to see what happens.
