Fridge is leaking refrigerant, do I have to buy a new one?

Tell your dealer to go back in their records and check to see if the problem may be related to a "recall" that Norcold had out on some of the frigs a few years back. You could luck out and have it replaced under the recall program. The recall goes by what Serial# the frig is so they should be able to check it rather quickly. If I recall it was related to a leakage problem.
