If the Portable Power Watchdog Surge Protector # HU87FR was limiting the voltage running to your RV then it's most likely a bad control module and you'll need the Replacement Surge Module for Power Watchdog Surge Protector with Emergency Shut Down # HU58FR. These modules are model specific so you'll want to ensure you're purchasing the correct one for your model. I've listed the modules and their compatible systems below incase you have a different one.
The # HU38FR fits the # HU47FR
The # HU48FR fits the # HU97FR
The # HU98FR fits the # HU67FR and # HU77FR
The # HU58FR fits the # HU87FR and # HU27FR
