Welcome to the forums and one of the most debated subjects, even though you put (Not residential). By using the advanced post option you could have made it
(Not residential) but doubt even that would help.
Unfortunately I have spent more time than most on my 1200 partly because I forgot to turn it off when parked in our fairly steep driveway the night before leaving on a trip. By vibrating the coils when it stopped working over the next three years I was able to keep it working BUT not as cold as you really need. Finally replaced the cooling unit with a Armish cooling unit which has helped a bunch.
The Nocold recall/bandaid is a
POS and you should have Revision D of it... yes there were A,B,C and D can be reset with a strong magnet because they turn off the reffer so often when there was not a over heat (800 degrees) in the burner area. The problem comes when it actually did it's job (not in your case) and someone resets it without monitoring the flue temps or smelling for ammonia behind the unit.
I've added a smoke alarm and a auto fire system behind my unit (before putting in the Amish cooling unit) as I've seen too many rigs that burned because of a fire that started behind the reffer and most were 1200.
This morning I'm going to install this
MOD which is a much better way of protecting your reffer (and your rig) than the NoCool recall box. It is a thermal sensing unit that mounts on the boiler in the flue and shuts the unit off at 300 degrees and would have saved my unit from damage when I parked too far out of level. Yes I had a recall box on my unit at that time. This unit will restart on it's own once your unit cools down and the display lets you know it shut your unit down.
OP, at this point I feel the ARP mod is what I would spend my money on to protect your 1200 as it's not a dumb bandaid like even the Rev D.
