Question about Thetford Norcold N323 1.7-cu ft 3-way Built-in Refrigerator

1 Answer

I have a Norcold 323 Refrigerator in a camper that will not cool when operating on AC but does work on gas, ( I cant test the DC as I dont have a 12 volt power sorce). After running in on gas for a while I whitched over to AC and it appears to be running. What could be the problem? The unit is only used a couple times a year since it was purchased in 2005 and hasent been used for the past year. Does the unit require a jump start with the gas after sitting unused for long peroids of time

The unit runs on gas(LPG) so the unit is operational
by ac I take it you mean mains power and by dc you mean 12 volts it being a 3 way cooler
you cannot "jump start" a gas system so I am a bit lost with that statement
check the heating element in the unit for continuity as both the mains and 12 volt power only heat and element that boils of the coolant liquid in the system the same as the lpg flame does
it could be a relay problem for the electrical part

SOURCE: DE0061 draws power when not cooling

Hi captstu,

I'm Harvey th Master Plumber.

Your question is: Can you install an auxiliary thermostat on the DC power feed to stop the power draw when cooling is not required?

I understand your frustration. I live on a boat. Since the fridge thermostat is reducing the amp draw when the compressor is off, just remember to turn off the curcuit when you leave the boat and emptying the fridge. You are probly doing this already. Since any modification to a new unit voids the warranty I wouldn't go down that path. The unit should have been tested before installation. Water under the bridge. I agree with the manufacturer. I would tear it out and get a warranty replacement. Sorry, Norcold is right, this is the least painfull way out. It is beter than the cost of repair.

Feel free contact me again!

I shut down the fridge. Not getting any power to it now. I have checked breakers and fuses. There is power to 110 outlet where it plugs in. No power to gas valve. What do you think the problem is?


Your Norcold refrigerator is powered by 12V DC, not 110V AC. You need to check input power at the power board. If the fuses are good and you have good 12V to the refrigerator, check to see if you are getting 12V past the 5amp fuse on the board. If not, you may have a bad board.

Norcold fridge in my motorhome


Norcold fridges are now part ofThetford one of the largest suppliers of mobile and marine products. You do not quote the model so not sure if a 3 way (gas/mains/12v) or AC/DC. The most common problem with all mobile fridges is the heater unit is faulty. Thetford have discontinued spares for a large range of norcold models. Information can be obtained on the Thetfold.com website.
Good Luck

Sounds like the unit may not have enough DC power. See the manual.

Will not run only on gas but will not cool


If it works on gas and NOT electricity then the heating element is not getting power or the heating element is open. The heating element is located on the tubing just aft of where the pilot flame is on the bottom of the copper tube. You should check for power to the heating element and with power off perfom a continuity check on the element. I really do not at this time think you have a heating element problem.

There is a 120VAV element a AND a 12VDC element. The chances of both of these failing at the same time is pretty slim.

There is a note in the manual:
If the gas only pushbutton is depressed the
lamp will illuminate green and the refrigerator
will only operate on the LP gas mode, even if q
120 or 12 volts are available.

Another significant change in the third
generation A.E.S. system is how the 12 volt
heating element mode operates. As with the
first and second generation series, the 12 volt
heating element circuit is energized by the
ignition lock terminal. This terminal receives
its DC voltage from a wire that runs from the
run side of the vehicle’s ignition switch to the
refrigerator’s ignition lock terminal. This
allows the 12 volt heating element to be
energized only when the RV is traveling down
the road.
When the ignition lock terminal is energized
by the ignition key, the printed circuit board
must see at least 13.3 volts DC for a period of
40 seconds before the system will activate the
12 volt DC heating element.
If 13.3 volts is not achieved in this time frame,
the electronics will light the LP gas burner and
the refrigerator will operate on the LP gas
mode.
LOWER THAN 13.3 V.D.C. =LP Operation

If the battery voltage remains low after the
delay cycle, the automatic controls will light
the refrigerator on the LP gas mode and stay
on the gas mode until the printed circuit board
sees approximately 13.3 volts DC to the
terminal block.

For proper cooling on the AC mode, the AC
voltage to the refrigerator should not vary
more than 10 percent from the voltage rating
on the heating element. Heating elements used
in Dometic refrigerators could have a rated
voltage of 110 volts, 115 volts or 120 volts AC.
Because of this, the power requirements for
each differently rated heating element will
vary. For example, if a heating element is
rated for 100 volts, the acceptable power range
would be between 99 to 121 volts AC. If an
element is rated for 115 volts, the acceptable
power range would be between 103.5 to 126.5
volts AC. If the heater is rated for 120 volts,
the acceptable AC power range would be
between 108 to 132 volts AC.

The unit to operate on either AC or DC must have 13.3 volts to the unit. I think this is where your problem lies in that the battery voltage is less than 13.3 VDC


If all of that checks good just repsond here and I will help you. There is still more that can be checked.

Thanks for choosing FixYa.

I know this is a vague question. (trying to help out hubby) I am currently at work, however, our norcold elect/gas fridge/freezer in our mallard camper stopped working properly. the lp gas light is lit,...


Don't be despirate.

You need a little more knowledge ... I'm here to give it.

Your RV refrigerator requires 12 volts to operate; on gas or on electric ... it needs 12 volts - period.

Now then, your frig will get 12 volts from your 'power converter' AND/OR your battery. You do have a battery in your unit, correct? If not - why not? Get one. (Your power converter cannot provide all the 12 volts you potentially require in all circumstances. It is there to charge the battery, which CAN supply all the 12 volts you require. The converter can probably put out 15 amps - your battery can put out 100 amps or more (@ 12 volts DC). Relying only on the converter for your 12 volts will cause over heating and will eventually destroy the converter. Batteries are about $100.00 - converters are about $300.00.

As you know, your frig will run on gas if you are plugged in or on generator ... that allows your frig to get the 12 volts required to run the controls.

What about electric operation? If you are plugged in or on generator, you can run on electric because your Norcold has 12 volts from the converter and/or battery.

Whats going on? Your absorbtion type refrigerator requires a heat source to boil the ammonia mixture to create "heat removing" (you can't really cool anything ... only remove the heat from it!) You can heat the ammonia with a flame or with a electric CALROD. However, the control panel that drives the whole operation runs of 12 volts.

You have a battery and generator and are plugged in and it still doesn't work? You will find a fuse on the control panel in the compartment accessible from the outside of your unit. Check/replace the faulty fuse and you will be back in business.

I hope this helps you and hubby with your Norcold Frig. Thanks for your interest in FixYa.com. If you found this solution to be helpful, please vote. Thanks

Will work on ac but not dc. I checked that it has 12 vdc on the wire leaving the boat fuse panel.


Wiggle element out of sleeve and lift up while wiggling. Once element is out, attach to 12vdc from battery or other source and see if it heats up to touch, if not, replace it. Careful, may get real hot to touch.
