I had the same problem. I installed a pancake fan above the monitor and removed the insulation around it. This is a common problem with the older crt monitors.

Norcold 1200 lrim 

It just so happens that I have the norcold cooling setup that I removed to install the jc refrigeration unit. First $100 plus shipping gets it.

Catapillar fault code 151 has to do with engine coolant temperature high, possibly low coolant level OR a clogged DPF, depending on where your google search leads you.  Fault code 102 fmi 4 relates to the intake manifold pressure sensor. I lean towards a clogged Diesel Particulate Filter causing your problem. I don't know much about the Cats, but on my Cummins with a DPF problem, I can do a manual regeneration to (hopefully) clear the problem up. Good luck!

https://wackoproducts.com/ provides the silencer for coleman and duo-therm ac units. I used the duo-therm on mine. It took about a hour b/c I was taking my time.

Dometic, sorry

No but I did install the Wacko silencer on my unit. Qiuted it down such taht you almost have to listen for it to hear it run.

I have a recently removed system from a norcold 1200lrim. It was working fine when I took it out. Pm me if you’re interested. I’ll give you a fair price
