My Norcold Fridge will not operate on AC

Based on the information provided, it seems that the Norcold N611R fridge in the travel trailer is experiencing issues with cooling on AC power. The green and yellow LEDs are blinking, and the fridge stops cooling after running for a random number of hours. The gas cooling seems to be working fine, and the fuses, AC/DC power, and power board have been checked and replaced.

One possible cause of this issue could be a faulty heating element. To check if the heater is working properly, you can use a multimeter to measure the resistance of the heater. The resistance should be between 44 and 52 ohms. If the resistance is outside of this range, then the heater may need to be replaced.

Another possible cause of this issue could be a problem with the thermostat or temperature control system. If the temperature control system is not functioning properly, then it may not be able to maintain a consistent temperature in the fridge, which could cause it to stop cooling after a certain amount of time.

It is also possible that there is an issue with the wiring or connections in the fridge. If there is a loose or damaged wire or connection, then this could cause intermittent cooling issues.

In order to diagnose and fix this issue, it may be necessary to consult with a professional technician who has experience working with Norcold fridges.

When gas is leaking, first fridge will stop working, than the freezer. I hope you dont have gas leaking. Is the compressor running all the time?

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 You do not quote the model so not sure if a 3 way (gas/mains/12v) or AC/DC.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

you can reset the control board . to do this you must ground the # 15 terminal with a jumper wire to ground. this is usually the terminal next to the white & violet wire. check diagram.

There should be a code appearing on the display. If you are not getting any 12V to the Fridge your fridge will not function. You may also want to check for any blown fuses inside the electronic board assembly. ">

The N611 will flash 3 times as an AC heater fault. If your AC heaters are ohming out properly (48 ohms of resistance), then you have a bad power board. If the AC heaters are not showing around 48 ohms of resistance, replace the AC heater. It's going to be one of the two. Here is an article on it:

Try to unplug it from the battery a few hours and then plug it back in and see if you are now able to select the AC or LP mode. There has been a recall on the 1200LRIM, The defect is a potential cooling unit leak caused during AC electric mode operation. Click on the link below to read more:

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

Most of the time if the unit has lost a/c gas and 12 volts which puts the unit into a defrost mode so there is a simple reset that can be preformed by unplugging the a/c cord from the back of the fridge and the 12 power going into the control box. leave them disconnected for about 15 mins and then reconnect them in the reverse order and check the inside frezzer at the back and fins on the rightside of the inside of the fridge to see if the unit gets cold
