Elevated Fridge Temp Issue

1. You ARE level?
2. Your temps do not compute 0 in the freezer but only 60 in the refer?
3. Based on your temp readings, your Norcold should be in LOCK OUT(n or NO/CO)
4. I believe your temp readings from your last post, but the refer should be locked out.
5. Based on your temp readings, it would indicate a blocked Cooling unit. Your temp readings are exactly what a blocked cooling unit would do. But, I do not believe you have a blocked Cooling Unit.
6. You need an LP pressure test to verify the LP pressure is correct (11.5 inches w/c).
7. You need to operate on 120 and see what happens. Doug

PS, since the refer was removed for the repair, it is possible when they reinstalled, they caused some type of rear ventilation blockage or damaged the upper cabinet that seals off the rear top cabinet of the refer. Being in a slide room, the ventilation is critical, but as I stated, the refer should be in lock out mode.

Doug,

1. Thanks for your input. I verified trailer is level using the trailer levels and using a level on the floor in front of the fridge. The trailer is in it's normal concrete pad parking spot in our back yard parking spot.

2. I have switched the refer to ac operation to determine if this is a gas issue since outside temp is 78 at 6:00 AM. I only have 15A electrical service so always run fridge on L.P. when I need the A/C to operate. Will operate refer on generator if I need to turn A/C back on when the sun starts heating things up

3. The control panel on our Norcold only has two LEDs so it can only indicate faults by lighting the LEDs or flashing. There are flashing green LED codes for temp sense failed operating in backup mode, ac heater failed and fault with refer controls. Not sure if the last code is the same as the NC lockout code you mentioned.

4. With respect to L.P. pressure, What kind of gauge is used for measuring that and where would I find one? The range burner looked normal when I bled the gas line after turning on the tank valve in preparation for turning the refer onvbut don't know if that is a good indication. I am assuming that the regulator would be the most likely cause. I believe I have a spare dual tank auto switchover unit I can substitute if the electric operation test shows much improved refer temps. Is there a possible issue if you open the tank valve to quickly?

5. I will check temps in an hour (switched to ac around 5:45 AM)

6. This morning at 5:30 still operating on LP the refer interior temp was 49.7 the lower refer vent inlet temp was 81 and the upper panel exhaust temp was 118 deg so lower ambient temps helped but not near enough.

If it locked out, it will blink but you could not run the refer or operate the controls. You would have to turn it OFF for 10 seconds and back on to remove the lock out. BUT, if it did lock out and you turned on and off and restarted, if you did not find and fix the problem, it would lock out the 2nd time and the board would not function at all with out a board reset.
