Bathroom light switch cuts off radio

We have a 2018 Big Horn Traveller picked up 3 weeks ago brand new. When we turn on the Jensen sound system radio in the living area and then turn on the bathroom light switch it shuts off the sound to the radio. Shut off light - sound comes back on. Any ideas how to fix? Waiting for dealer to get back to us but they are very slow at responding to issues we have. Thanks.

LED lights in the bathroom? If so radio interference, probably kills TV also.

Our used to cut off all TV reception, when we turned our bedroom lights. Never did fix the issue, just learned to not watch TV and leave the bedroom lights on. Some type of RF interference was being generated by the lights somehow.

Like others have posted, this is probably a case of Radio Frequency Interference. Sparking bathroom fan motors and digital dimmers/drivers for LED lighting systems have all proven to be culprits. You need to filter out these radio frequency transmitted signals as near the source as possible. You might try one of these ferrite choke filters on each wire going to/from the LED controller switch: https://www.ebay.com/itm/5pcs-3-5mm...539743?hash=item23a9acf4df:g:f0sAAOSwVH5bkjrZ

Also, soldering in .001 mfd ceramic capacitors between the hot and ground wires on each side of the switch will make a radio frequency (but not DC) "short" that will attenuate the RFI signals. https://www.ebay.com/itm/10-NEW-RAD...012488?hash=item590d869288:g:Li4AAOSw4WRbEYHx

The wires to/from the RFI generating devices act as transmitting antennas.
