My OEM Winegard RV-7542 failed in March with visible corrosion. Replaced it and the new unit has failed 6 mos. later with the same issue. RV dealer says the corrrosion might be due to a leak in the wall of my 2007 FR Wildwood with aluminum lap siding. Does this sound right?
We run a dehumidifier 24/7 inside set at 55% RH to keep it dry. This summer we also set the A/C at 83 deg F to keep the interior cool. Trailer is located in the deep woods of No. Florida where rain and humidity are always a problem.
Question: How do I troubleshoot if there is a leak in the wall? Do I need to add silicone caulk to the lap edges of the siding in that area? Keep in mind that this power supply is located above the kitchen countertop/sink and below the cabinets above with limited wall access.
Worried. Left a VM for FR Tech Support help yesterday and got no call back. Any suggestions from other owners appreciated.
