New Member with Electronic question about 26BH
First time posting, just joined this forum today.
The wife and I own a 2012 Jayco 26BH.
We first noticed a sharp whistling sound emanating from below the fridge (where the breaker panel is) when we turned on the TV, or radio.
Since then I have done some testing and it happens when we turn on the interior lights, or the furnace is running. Haven't tested the microwave or when the fridge is on.
When turning off the first breaker from left to right on the breaker panel, the whistling stops. When I turn off the 3rd breaker from left to right the whistling stops. All other breakers do NOT stop the whistling when turned off.
Any idea what could cause such an issue?
