Power Interruptions - Transfer Switch?

Our 2021 Montana 3121RL Legacy edition is outfitted with the generator prep kit which includes a transfer switch. We have not had any problems in three months of use and now we have intermittent complete 110V power failure in the trailer and can hear a clicking sound. This fifth wheel is also equipped with the power surge protector from Keystone's Vendor.
I have a meter plugged into the wall - it shows voltage present some of the time. We hear a clicking sound from the storage compartment when the power fails and it seems to try to reset because the voltage meter has a reading for a minute and then it goes dead again - not sure what to do except ask the experts here at MOC. I am a novice at this - is there something I should check?

There have been a LOT of the combination transfer switch/surge protector unit issues in the last couple of weeks. It sounds like we can add you to the list. So far, it sounds like Progressive Dynamics is doing a good job of standing behind their product. I’d be making a phone call to them in the morning to see what they have to say. 269-781-4241 They also have a troubleshooting guide on their website. progressivedyn.com
