Speakers quit when furnace comes on
I've had my 2019 Globetrotter for two months now. My problem is that when the furnace comes on my stereo speakers quit. The stereo (POLK Audio PA4A) stays on but I have to turn it off and back on to get the speakers working. If I leave the speakers off, they will come back on when the furnace comes on.
I previously had an issue with the furnace not coming on at all but the dealer replaced the main board on the furnace and it has run flawlessly since then.
Any help will be appreciated. Thanks!

Hmmmm. Speakers cut off when Furnace comes on and return to normal when Furnace cuts off. Is that correct?
Then if you turn Polk head unit off while speakers are not working (Furnace still on)
And then back on the speakers work?
So problem only occurs when stereo is playing and furnace comes on?
Hmmmmmm. Please confirm, I’m thinking this one through.

Speakers come on or go off when furnace comes on as long as the stereo is in Auxiliary mode. No change when the furnace goes off.

Speakers coming on
EMI induction from the furnace starting up somehow causing a false signal ?
Or the furnace electric is some how providing a ground or a hot feed?

That was my thought. Loose ground, hot to Ground or Electromagnetic interference.
Did it happen with the original furnace board?

You have purchased a haunted trailer. Time for an exorcism.
