Hi Chris
The very first Dometic I saw is a newest model . The 2 in the boxes never worked from the outset .
From what I gather it's a raft of failures - incl compressors ......but it's the electronics mainly . The motherboards that control the compressor , the power circuitry & the LED display.
Apparently they don't test these things before they are packaged . Not only do they need to be tested - they need to be run for a few hours . ..... If the fan stops / doesn't work - the circuitry will fail . This is what has happened with mine.
