Daryl, welcome to IRV2 glad to have you aboard.
As far as I know the led is just an indicator that its on. Never had a problem with it other than a snowy pic if its off so amp is off.
If you post down in the RV SYS AND TECH SECTION of forum you may get a answer also. Lot of people that know more on this than I. welcome again and enjoy the forums.
