Norcold controls

I'm trying to figure out the controls on my campers fridge.

I can't read the model on the label, but can read that it is 3 mode. I have the original documentation provided with the camper, and the fridge manual says it is 874EG2, 874EG3, 875EG2 or 875EG3.

GAS vs ELECTRIC is pretty strait forward. The 'ignition' switch on the right is pretty strait forward. The brown switch on the far right, according to the manual, should be AC up and DC down. Mine is instead labeled 'ON' up and 'OFF' down.

If I'm running in GAS mode and have the brown switch to OFF/DC, the fridge appears to run on gas with minimal battery impact. If the switch is set to ON/AC in GAS mode, it runs my battery dead in about 6 hours (but gets VERY cold); this test done not on shore power.

If I plug into shore power and set the switch to ON/AC and the dial to ELEC it appears to run on 110v.

So what I can tell:

Brown switch ON I run on power, whether or not I'm in GAS or ELEC on the dial. It seems to detect if its 110v or 12v?

Can anyone clarify if that's right (which doesn't really make sense to me) or if I'm missing something?

Revisiting this (because someone PM'd me about it).

When the knob in 'electric' and the brown switch 'off' it runs in 110V mode. In the absence of shore power I can flip the brown switch 'on' and run in 12v mode. Which slaughters my poor house batteries. Will probably never use that. 😉

Due to a potential safety defect, Norcold has voluntarily recalled the smaller gas/electric refrigerator models, built from Jan. 1987-May 1995, listed above.

If your refrigerator model's serial number is above, it requires immediate service. Refrigerator model and serial numbers can be viewed by looking on the inside right of your refrigerator cabinet.

Continued propane gas mode operation of a refrigerator under this recall could result in a fire.

If you own an affected model:

1. Immediately switch your refrigerator's controls to AC power (or DC power, if available, while in transit). No LP gas power operation should occur because it could create an unsafe condition.

2. Contact a Dealer/Service Center to arrange a service date soon. The gas valve in your refrigerator will be replaced at no charge.

Call Norcold at 1-800-667-3005 with any questions.



N600 and N800 Series Models
1082 Free-Standing LP Model
Norcold has voluntarily recalled N841, N821, N641, N621 and 1082 gas/electric refrigerators built in 1999. Affected models have a cooling unit serial number (found on the solution chamber and viewed through the refrigerator vent door outside the RV) from 1038000-1099000.

The defect is a potential cooling unit leak caused during AC electric mode operation. If a leak occurs, the refrigerator's cooling performance will deteriorate and a yellow powder residue will be evident at the cooling unit's heating element. Because extended operation of a leaking cooling unit in the AC electric mode may result in a fire, immediate replacement of the cooling unit is required.

Some customers have previously had a heater element in your cooling unit replaced - we now want to replace the entire cooling unit in your refrigerator.

We regret any inconvenience this may cause, we do want to assure your refrigerator provides you years of safe, reliable and dependable service.

An affected refrigerator without a leak must still be serviced to have its cooling unit replaced to prevent any potential future problem.

Persons owning one of the affected models should:

1. Immediately switch the refrigerator's controls to the manual mode and select LP gas as its method of operation.

2. Open the outside access panel and unplug the electric cord from the refrigerator.

3. Contact a Dealer/Service Center to arrange a service date as soon as possible. The cooling unit will be replaced. There is no charge for parts and labor.

4. Call Norcold at 1-800-767-9101: with any questions; to obtain the location of the nearest Norcold Service Center; or if the Dealer/Service Center fails to, or is unable to, remedy this defect without charge or within a reasonable time.



1200LR and 1200LRIM Series Models
Norcold has voluntarily recalled 1200LR and 1200LRIM model gas/electric refrigerators built from 1996 through March of 1999. Affected models have a cooling unit serial number (found on the solution chamber and viewed through the refrigerator vent door outside the RV) from 700000-1008700.

The defect is a potential cooling unit leak caused during AC electric mode operation. If a leak occurs, the refrigerator's cooling performance will deteriorate and a yellow powder residue will be evident at the cooling unit's heating element. Because extended operation of a leaking cooling unit in the AC electric mode may result in a fire, immediate replacement of the cooling unit is required.

N260, N300, 322/323 Models
Norcold has voluntarily recalled three small gas absorption/electric refrigerators, primarily used in folding camping trailers, which potentially could have a safety defect involving stress corrosion cracking in brass swivel nuts on the their pressure tap components. A significant crack could potentially cause propane gas leakage during gas operation of these units:

Models – Built – Serial Numbers (found on the ID Label inside the refrigerator)

322/323 – August, 1992-August, 1999 – lower than 734882

N260/N260.3– April, 1998-August, 1999 – lower than 738527

N300/N300.3– April, 1998-August, 1999– lower than 738626

Persons owning one of these models should:

1. Turn the manual shut-off valve to OFF and operate it only on AC or DC power until the defect is repaired. (No gas leak can occur during AC or DC operation.)

2. Contact a Dealer/Service Center to arrange a service date as soon as possible. A remedy kit, and the labor to install it, is free to the consumer.

3. Call Norcold at 1-800-767-9101: with any questions; to obtain the location of the nearest Norcold Service Center; if the Dealer/Service Center fails or is unable to remedy this defect without charge or unable to service the refrigerator within a reasonable time.

Good thought on pulling the switch, will do so tomorrow.

I saw that recall, I intend to contact Norcold tomorrow with my serial number to see if it has been done or not. Two owners ago this camper was very well maintained, and then the owner prior to me beat it like a baby seal.

Hard to know if it was done or not.

To me it looks like the original AC/DC switch has been replaced with a toggle switch/plate........just doesn't look OEM.

Couple of issues.
With mode selector switch in 'gas' no electric heating AC or DC should occur
With mode selector switch in 'electric' AC heating (with shore power) should occur when AC/DC switch is UP. DC heating (from battery power) should occur when AC/DC switch is DOWN.
With mode selector switch in 'OFF' nothing should heat (gas, AC or DC)

I would remove AC/DC switch with plate........pull complete plate out with switch......and check which contacts have AC voltage and which have DC voltage.
And check that NO voltage flows thru switch when mode selector switch is OFF or on GAS

One other thing........those models of compact fridges built between 1987 and 1995 had a recall on the gas valve. Recall involved replacement of gas valve. LINK
