My Norcold Refrigerator signaled "no co", I turned it off and back on, it ran for several hours and "no co" came on again. I went out and took the vent cover off, saw "lime-green" residue, AMMONIA. Called Norcold of course my refrigerator was not on a recall. Talked to a man in Indiana he had a new cooling unit for $900.00. Talked to **** Albritton RV about installing a Residential Refrigerator. I found a Whirlpool 21 cubic foot that would fit where to Norcold was. I now have frozen ice cream, not soup like in the Norcold. More important I eliminated a FIRE HAZARD. Friends lost their motorhome 2 years ago due to a Refrigerator caused fire. I helped put out a MH fire in Florida last March caused by a Refrigerator. The adjuster that investigated that fire had 3 more to go to. I have RVed since 1965, have had Gas/Electric Refrigerators with no problem. The last 4 or 5 years there has been a lot of fires caused by leaking ammonia. They must be making the refrigerators cheaper, because they are not holding up like the older ones. **** Albritton installed 2 residential refrigerators this week, including his own.
