Refrigerator problem Pilot 30 II
I have a 2004 Mainship Pilot 30II with the top loading refrigerator. I usually keep a few drinks and condiments in the fridge, and keep the AC Outlets switch on constantly when I'm away from the boat to keep the fridge running on shore power, and keep the drinks cool. In the past the fridge worked so good that it could freeze drinks at less than half way up on the dial. Recently I noticed a little defrost water in the bottom at the same temp I usually run. I tried turning it up, thinking perhaps the heat of the Summer was causing it to struggle to cool. Now it seems it barely cools, even at almost full on the dial. I can hear a hum near the bottom, so something is running, but it's just not cooling much.
Can these be repaired, or do you just replace when they go out?
