Norcold 962 fridge giving error code; dc voltage too high

[Cheryl_B]

Here I am in a campground, finally able to plug in my rig and enjoy the relaxation that comes from shore power and all the other niceties. I get an A8 code. I look it up and it says the dc voltage is too high. I check the converter and fuses (cause I read that it could be a bad converter) and couldn't see anything wrong.

The light in the fridge wouldn't come on although the display was still visible on the door and it wasn't beeping at all, just showing that A8. But I started noticing the temperature slowing beginning to rise and it was getting into the upper 40's, so I unplugged from shore power, went back on LP and she's fine again.

Well, I want to plug the dog gone thing back in. I'm paying for this electricity and these comforts, so if you can help me to figure out what could be causing this, I will try whatever you say. I have researched and done my homework and even sent an email to the "norcold guy". Waiting for his response.

Got the power turned off at the pole and got the temp turned all the way down on the fridge to get it as cold as I can get it before I plug back in, a few hours from now. I will need the power to run the furnace. I'll have to shut the fridge off for the night and just keep the doors closed.

Is this really "living the dream"? Or is it just me?

Thank you for that. It's not a high temperature code, it's a "dc voltage too high" code, but I'll check your instructions and see if I can do anything with them. I'm no electrician and that seems pretty involved. I appreciate your input though.

How to reset the refrigerator high-temp switch (L1-oP error code)

1. Leave the refrigerator turned on.
2. Access compartment door on the outside of RV.
3. Locate the black plastic recall kit box. Confirm that the red LED is lit and not flashing. (If it's not lit or it's flashing, you have a different problem, so these instructions don't apply.)
4. If the recall kit box is not easily accessible, pull on it gently to remove it. It's held on by a simple spring clamp. Use caution as some of the wires leading to the box may be short, and you don't want to damage the circuit board by pulling on them too hard.
5. Slide your flat-blade screwdriver into each of the three clips that hold the box cover onto the base to open the clips. Lift the cover off the base. Do not detach any of the wires attached to the circuit board--the board needs to be powered to reset the switch.
6. Touch your hand and your magnet to the metal interior of the compartment to discharge any static electricity.
7. Locate the 'reed switch' on the circuit board. It's directly above the lit-red LED. It looks like a small black rectangular component, about 1/2" long and 1/8" wide. It says "SWITCH" next to it although your circuit board may look different as there are different revisions of the recall kit.
8. Touch a magnet to the right end of the reed switch and hold it there for about 5 seconds. (Avoid touching any other part of the circuit board.) Simply moving the magnet around the switch won't do it; it takes prolonged contact at the right spot. When the switch resets, you may hear a faint click, and the red LED will go out.
9. Go inside and verify that the refrigerator is on, stopped beeping, and the front panel display shows no messages.
10. Wait 15-20 minutes to be sure that the refrigerator continues to operate normally (there some reports of the switch tripping again after a reset; maybe due to residual water on the circuit board)
11. Line up the three clips on the recall box base with the cover, and press the cover into place so that the clips snap shut.
12. Re-clamp the recall box in its original location. Ensure all the wires are firmly connected to the circuit board.
13. Replace the refrigerator access compartment door.

NOTE: this is for informational purposes only. although this worked to reset my error code, use this at your own risk.

120V AC voltage range-----108V AC (min) to 132V AC (max)

12V DC voltage range -----10.5V DC (min) to 15.4V DC (max)



Do you have a voltmeter?
DO you know how to use one?

Measure/verify WHAT the 120V AC voltage is AT the power pedestal receptacle
High AC voltage WILL cause converter to put out HIGH DC Voltage

Have CG maintenance measure their receptacle AC Voltage


If good..
Then measure Converter DC OUT right on fuse dist panel (need to disconnect battery POS cable at battery so you get just converter DC Out and no battery voltage)

Either CG power pedestal or your converter is problem



YOU can use fridge display panel for Information
Press/hold TEMP & MODE buttons at same time for 10 seconds
7 info screens available....use MODE button to step thru the screens
Screen 5....displays AC Voltage
Screen 7....displays DC Voltage (decimal point is implied ie: 126 is 12.6V DC)


To exit.....press/hold TEMP & MODE buttons for 2 seconds

Well it says the voltage is too high. Is it?

You may be able to run the fridge on propane while connected to shore power.

Do you have a volt meter?
