L1 OP Code on Norcold Fridge--Help (Norcold Recall Issue)

1. IF you have REV E, then the likely cause is a false trip OR a leaking cooling unit. Older REV's could be tripped by 12 volt fluctuations.
2. The RV tech should do a thorough check of the burner area especially around where the recall temp thermistor is mounted for yellow residue. The past few that I have seen, that is where the leak was.
3. Are you positive the ventilation is clear from bottom to top? Doug
