Norcold issue once again

Well, here we go again! Norcold 1200LRIM frig on the blink again. Cooling unit replaced in February 2011.

Recall box installed at that time. Recall overheat sensor failed summer of 2013 and replaced under warranty with Norcold revision "E"!

Now I have mh in shop for blinking light on frig again, they changed the overheat temp sensor and running frig today, said it is working correctly. Called later today and said failed, think control board is bad, troubleshooting it tomorrow.

When is enough enough...and just put a residential one in...already out $2000 for the cooling unit 2 1/2 years ago now.....?

You said the LED on the recall box is "blinking"? I have NEVER seen the recall box LED blink. It is either ON(failed) or OFF. You do NOT replace just the Overheat sensor, you replace the complete kit with new recall box. Hopefully they did replace the complete kit not just the sensor. IF failed again at the shop, then the odds are you have either a failed cooling unit(leaker) or the ventilation is blocked. The normal operating temp of the refer is about 350 degrees. The Overheat sensor does not trip until over 700 degrees. So, if NEW recall kit installed and the new kit tripped, the system DID ITS JOB. It is not a false trip. Doug
