This page covers the follwing topics:
It has been reported that the Norcold recall false trips a majority of the time. This is evidenced by the 800degF set-point stated by Norcold ( Click here to understand the need for the ARP Control & why 800F is just too hot for Norcold recall trip point ). As a result of false triggers for the Norcold recall, operators get into the habit of resetting or bypassing the Norcold recall. This is a bad habit, if there is a failure of the fridge and one bypasses the recall, or turns off the ARP Control, a dangerous situation may occur. Thus, it is the responsibility of the user to know and understand all safety necessary to make the decision that the cooling unit has not failed before taking any reset or bypass action.

RESET: The figure to the left is a Norcold recall found on the 1200 series fridges. Our customers have informed us that these recall kits can be reset if there is a fridge off or not working situation. If your fridge is off, the first step is to see if the red LED is turned on? If so, Norcold recommends paying a service technician to inspect your system for leaks. If you are camping remote, and you are qualified to know the cooling unit does not have leaks, see next section. We state this because the most common cause of these recalls turning off is water on one of the controller parts.
LED ON: If the red LED is on, some of these kits have been reset by Norcold users when they can not get into a Norcold repair facility. Our customers have identified the area above the LED where a strong magnet may be applied to the box to try and reset it, we recommend having a qualified Norcold technician perform all repairs. We are told if one does not have a strong magnet, the cover can be removed by compressing the clips identified in the image to the left. Please use this link to identify the area to apply the magnet: Norcold 1200 Series Recall.
PLEASE NOTE, the Norcold control can be reset if and only if the boiler has cooled. Restated, the Norcold temperature sensor is not hot. It is possible to disconnect the temperature sensor plug found between the +12VIN and +12VOUT wires and put a jumper between these wires in order to fool the control. A strong magnet held for greater than 5 seconds should reset the control. Please contact Norcold to have your recall box replaced and have your fridge checked when you can get in for an appointment.
WARNING: Norcold dealers are not allowed to stock these controls so be prepared for a wait.
LED FLASH FAST (On/Off ~2 or 3 times per second): A Norcold service technician stated (not confirmed) that this could mean that the sensor is not connected to the recall kit. Or, the sensor that can be identified by red and yellow wires has an open circuit. Remove the plug found between the +12VIN and +12VOUT wires put a jumper between these wires. If the light quits flashing you found your problem.
LED FLASH SLOW (On/Off ~once per second): A Norcold service technician stated (not confirmed) that this could mean that the voltage supplied to your fridge is too low. In some documents the low voltage for a typical RV fridge is 10.5VDC, but this is just a rule of thumb. Customers have stated that the low voltage threshold is 9.5VDC on the Norcold recall. Use your volt meter to find the connection that has high resistance or charge your batteries. Also, failed inverter charging systems can cause problems. In this case, disconnect your rig from shore power and make sure your batteries are fully charged to continue searching for a high resistance connection that can lead to a voltage drop in your system. Please start at the RV source of power, which should be a fuse block.
The second drawing shows how power gets from your RV to the Norcold refrigerator control via the Norcold high temperature kit. Please use following link to see where the ARP Control can be with respect to these wires: Norcold 1200 Wiring.
If your fridge is not working, please start by checking your fuses and circuit breakers. If the Norcold kit LED is turned on, it can be assume that there is power to the kit. We are told that Norcold service personal will connect the red wire from the coach power supply to the blue wire to the Norcold fridge control to test the fridge function. If the fridge turns on, then the Norcold recall box has failed and a Norcold authorized service department should replace the recall free of charge according to our clients.
Please use the following link if a Norcold not working situation arises:
It is clear by

that the recall cannot
protect the boiler of your fridge
in order to help prevent failure.
As stated above, the recall leaves you stranded if it trips due to any other reason than a true failure
of the cooling unit. This is another reason to install the Fridge Defend by ARP, if someone bypasses
the recall -- as is reported to us often, you are left without protection.
