Hope someone can help, this is my first post on this group!
I'm having bother with the above trailer fridge, a Thermoking Spectrum sl, when switching the unit on all I got was every lcd on the display coming on, no background light and that was it!! I have checked all usual connections and fuses and thought the problem lay with the micro/control panel, I robb the micro from another trailer and plugged it in, switched it on and it immediately started cranking the engine for a few seconds, sometimes it will light up the screen, sometimes it will crank the engine and sometimes all or some of the lcd display will come on!!
Now when I fit the micro back to the original trailer the same problem occurs....
I now have 2 trailers down both with similar faults, 1 tries to crank the engine when switched on and the other just lights up the lcd and does nothing!
I'm really stuck and hope some of you guys can help, thanks in advance, Tim.
