6400 displaying OVERHEAT message while in RX

I have a Flex 6400 that is showing the OVERHEAT message and says that I need to reboot the radio.

  • This is in RX only - Radio was turned ON and after ~5 minutes in RX, it showed the message. NO TX had been done!
  • Removed the cover and found no accumulation of dust, etc. Used a blower to get out what wasn't seen.
  • Fan is working (at least it seems like it. No weird noises and it's moving at the right speed)
  • This is occuring more and more often. The ambient temp is around +25C to +28C while in RX. Never had this problem for several years and now we are seeing this.

For now, we can get out of this problem by rebooting the radio.

Any suggestions?

    Hi Bruno, I would submit a help desk ticket. Be sure to include the information in your original post.
