Short Answer
Your 2006 Newmar's Norcold refrigerator door has a common failure where the plastic hinge pin housing has cracked and broken away, causing the lower right door to fall off. Since you just invested in new $3,000 cooling unit components for 12V and propane operation, the most cost-effective solution is to either epoxy and reinforce the existing plastic hinge housing or replace the entire door assembly. Given that your other door is showing the same cracking pattern, you'll likely need to address both doors soon to prevent total failure.
Understanding the Problem
This is an extremely common issue with older Norcold refrigerators, especially in the 15-20 year age range like your 2006 unit. The plastic hinge pin housings are made from ABS plastic that becomes brittle over time due to constant temperature changes and the stress of door opening and closing. The lower right door typically fails first because it bears more weight and stress from the door swing.
The fact that your upper door is showing similar cracking means the plastic throughout your door system is reaching end-of-life. Since you've recently invested $3,000 in new cooling components to get both 120V and propane functionality, replacing the doors makes much more sense than replacing the entire refrigerator. The cooling system you just installed should give you many more years of reliable service.
The hinge pins themselves are usually fine - it's specifically the plastic housing that holds the pin that fails. This creates a cascading problem where once one door fails, extra stress is placed on the remaining door connections, accelerating their failure as well.
What You'll Need
**SAFETY WARNING: Before beginning any work, disconnect electrical power and shut off propane supply by closing the tank valve and waiting for the system to purge completely to prevent accidental operation during repair.**
For a temporary epoxy repair, you'll need JB Weld plastic epoxy or similar structural adhesive, small metal plates or mesh for reinforcement, sandpaper, and acetone for cleaning. If you decide on a permanent fix, you'll need replacement door assemblies.
Norcold door assemblies for your vintage unit typically run $150-250 per door depending on size. You'll need the correct part for your model (verify with dealer) from inside your refrigerator to ensure proper fit. Given your location in Temecula, CA, Camping World in nearby San Diego or RV supply stores in the area should be able to order the correct parts.
Basic tools needed include a drill with small bits, screwdrivers, and possibly a Dremel tool if you need to clean up broken plastic edges. You might also want to have some wooden shims handy to support the doors during installation.
Since both doors are affected, consider ordering both door assemblies at the same time to save on shipping and ensure you have matching components.
How to Fix It
For a temporary repair while you source replacement doors, clean all broken plastic thoroughly with isopropyl alcohol (avoid acetone as it can weaken ABS plastic) and sand the surfaces. Mix JB Weld or similar structural epoxy and build up the hinge pin housing area, using small metal plates or mesh as reinforcement embedded in the epoxy. Allow full cure time (24 hours) before reinstalling the door. This repair might last several months but isn't permanent.
For the permanent solution, remove the broken door completely and take detailed photos of the hinge mounting points before disassembly. Order replacement door assemblies with the same hinge configuration. Most Norcold doors from this era mount with screws into the refrigerator cabinet frame.
Installation involves positioning the new door assembly, ensuring proper alignment with the refrigerator opening, and securing with mounting screws torqued to manufacturer specifications (consult your Norcold service manual for specific torque values - be careful not to over-tighten as this can crack plastic components). Check that the door seals properly around the entire perimeter and that the latch mechanism engages correctly. You may need to adjust the strike plate position if the new door sits slightly differently.
Test the door operation thoroughly, checking that it opens and closes smoothly without binding and that the seal compresses evenly when closed. Given that you have dual functionality with both 120V and propane, verify that the door closure doesn't affect the operation of either cooling mode.
Leave It to the Experts
Given your location in Temecula, CA, there are several RV service centers that specialize in appliance repair. Camping World locations in San Diego or Desert RV Service in nearby areas have experience with Norcold door replacements and can ensure proper installation.
Professional installation typically costs $100-150 per door in labor, plus parts costs. This might be worthwhile given that you've already invested $3,000 in the cooling system upgrades. A professional can also assess whether any additional refrigerator components need attention and ensure your new 120V/propane system is operating optimally. Professional evaluation is recommended before attempting DIY epoxy repairs to determine the best approach for your specific situation.
Some mobile RV repair services operate in the Temecula area and can perform the work at your winter location. This is particularly convenient if you're staying in an RV park or have limited tools available. They can also check the upper door that's showing similar cracking and potentially prevent a future failure.
Professional service makes sense here because they can ensure proper door alignment and seal compression, which is critical for maintaining the efficiency of your newly upgraded cooling system. Poor door sealing can significantly impact the performance of both your electric and propane cooling modes.
