Norcold N611 Fridge 5 flashes

Doug, this unit is in a Jayco 30JTX, the reefer is not in the slide portion. I have investicated more and was going to try the suggestion you proposed next weekend when I get back to my trailer. I do not have an amp meter to test how many amps the heater is drawing but will try to get one for next weekend to confirm if the heater is within spec. Do the control boards go on these often?

Connect the 120 element to an extension cord and run for 24 hours. This bypasses the controls. IF it does not cool correctly, the Cooling Unit is bad. The NO CO (5 flashes) is a cooling unit protection. Is this refer in a slide room? Doug

I have leveled the trailer, do you think the cooling unit is faulty because after a reset it works very well, I can even make ice? I removed the roof vent cover and the vent is clear.

Was it level before?

Having it trip after 4-6 hrs.......resetting and then tripping again sounds like blockage. Unit turns on..begins cooling but due to blockage is finally reaching a point of no cooling detected so it trips.

Off level operation causes a slow down in fluid to vapor to fluid and begins to crystallize which builds up.........effect is accumulative

Vent is clear.......how about the air flow from lower vent across backside of cooling unit to roof vent.
Any obstructions OR excessive gaps/areas (dead air spaces)?

That is a 'no cooling detected' fault
Means you have an ventilation obstruction, excessive off level operation OR the biggy.....cooling unit fail
