Norcold Safety Question
Hi all, Have a Norcold question. We have had the fix (heat block sensor) as part of the recall a few years ago.Have there still been fires after the recall fix? Is the problem when hooked up to shore...

The recall should address the main safety concerns.
As I understand it, the problems had to deal with the metal fatiguing and cracking in the cooling unit due to excessive heating and cooling around the electric element (and possibly poor manufacture/materials). If a crack developed and the fridge was running on propane, the ammonia refrigerant under the wrong circumstances could be ignited and cause a bad fire. The recall fix prevents this by containing any fire and shutting off the propane if the temperature gets excessively high in the burner area.
The fridge should be reasonably level while running when not en route to ensure proper coolant circulation by gravity. (While driving, the movement of the vehicle helps keep things moving.) Generally speaking, if things are reasonably level for human use--if the shower drains properly and the cabinet doors don't all want to swing to the same angle and eggs stay in the middle of the frypan--then the fridge is more than sufficiently leveled.
Well covered......
Couple of points.
Recall Box is a high-high temp sensor. Shuts down all 12V DC power which turns fridge OFF (no control circuit) whether on electric or propane
OFF level........fastest way to KILL an absorption fridge. Due to no compressor they rely on gravity for ammonia solution to flow back down to absorption tank (bottom of fridge). IF off-level overheating can occur which causes the anti-rust inhibitor to crystallize, plate out of tubing, cause blockage..more overheating ......damage is accumulative and permanent.
Just 20 mins of off-level operation can cause this issue.
