After 3 1/2 months of getting advice from the great members on this forum, the Norcold N.300.3 fridge/freezer in my 2002 Six-Pac Camper — is now repaired — and working better than when new.
Much was learned along the way — and I will share a little of what I learned, diagnosed, and discovered —
With the gas control valve set at # (3) of the 5 positions — the fridge now cools down to 40 degrees for a few days — or as long as I keep it running. I switched over to A/C this morning — just to check all systems.
Next, the shop manual diagnostic box procedure was helpful to eliminate possibilities as I went through the next/next steps, in order.
Ended up purchasing some parts — likely not all were needed — but now I do not need to worry about something that I may have tried to “get by” with.
Purchased (2) parts from the NorcoldGuy — prices were high — and his response to my emails for advice on next steps was “0”.
Purchased a new pair of wires that connect from the interrupter to the selector switch and gas valve.
Purchased a new interrupter.
Purchased a selector switch.
Purchased a thermocouple.
Purchased a new regulator for the gas system.
Purchased a complete gas valve assembly.
Replaced the burner tube and the orifice.
Spent about $400. A New unit would have been $850, delivered to my house from Adventure RV, the lowest price.
Prices for factory Norcold parts on Amazon — were approximately 1/3 to 1/2 less than going through the NC Guy, or Norcold.
All parts were sealed original Norcold parts.
Everything was completely cleaned of the crud and mud wasp infestation — plus, mesh screens were installed underneath the roof mounted chimney cap, and also on the (3) vents on the side exterior access for the rear of the fridge.
I will try to add some photos to this post using the procedures that Old Crow helped me with. We will see how that goes.
Thank you all — for all of the help and advice.
Project completed.
Best Always,
Fred
