Our 2018 FOREST River Legacy Class A 50 AMP has a Precision Circuits Inc. touch panel screen. When open you can turn on the propane, the air conditioners, the lights, check the power control such as AMPs to the unit etc. An electrical issue seems to be occurring so we took it to Camping World (CW) for a diagnostic. Their final decision was that our surge protector was bad. So, we had them install a unit direct in the shoring compartment. Only to get home and find that we still have the same issue.
Intermittently the power panel shows “Brownout” on one line or the other. Nothing in the coach stops working though. Electric seems to work and no breakers appear to flip. Its difficult to know when this occurs because nothing changes in the coach. Lights still work, fridge still works, both air conditioners still work. You have to keep checking the Power Control on the Precision screen. This is the same control we check when we shore to a 50 amp service to be certain we have 50 AMPs at our location. We look at it from time to time, maybe a couple times a day. The “brownout may show on either line or both and may occur with two air conditioners, lights fridge running or with only the fridge and nothing else running. Before taking it to CW we turned everything except the fridge off and the power panel showed we had 50 amps of service with 1 amp being used on one line. The next morning we had “brownout” shown on both lines.
The CW techs plugged the unit in and ran it for two days with everything on. Brownouts occurred. They checked the shoring line and transfer switch and they appeared fine. The battery inverter seems fine. Quite frankly both techs seemed puzzled and didn’t know what else to check. So they decided it was my surge protector causing an issue. Even though, when running the unit they plugged into their service with and without my surge protector and both had the “brownout”message at some point. They installed a direct line surge protector, all was working well so we headed home. Within a couple hours of being home, plugged to our 50 AMP, one line showed “brownout”.
I am not mechanically inclined but apparently neither were the techs at CW. Does anyone have a similar Precision Circuit Inc screen and have you had any of the above mentioned issues?
