Check the thermistor by unplugging it from the main circuit board located at the back of the refrigerator. It will be the harness to the left that has only two wires in it. Unplug it and allow the refrigerator to run for 24 hours. If it does not cool after that then you have a bad cooling unit.

Make sure the thermister is attached firmly to the fins in the back. The boards on a Norcold can be reset a service center familiar with this process is your best bet. It takes disconecting the board and then shorting it out best to leave it to some one who is familiar.

SOURCE: Norcold Fridge will not work on LP gas while traveling.

One of two problems. The auto switch is bad or the lower circuit board is not doing its job. You can call norcold technical or take the board to a service center and have it checked with the tester they should have. The lower board retails for 176.00. I looked at my tech file and it is a little vague on your particular situation. If I were repairing your fridge I would take the smart route and call technical. Hope you get your problem solved. If you need more help please feel free.

Yes. LP is direct heat to the exchanger. The thermistor operates through the control to the electric heater.

It sounds like your cooling unit is going out. Here's a couple of things to check. Do you smell any ammonia when you open either one of the doors? When you look at the rear of the fridge, do you see anything that looks like rusty water that has run down any of the metal tubes and dried up? If the answer to either one of these is "yes", then youll need to start looking for a new fridge or replace the cooling unit on the one that you have.

SOURCE: Our Dometic RM2193 cools on gas but does not work on electric

It could be as simple as a blown fuse at the fridge. Also check to make sure you have turned on the electric switch that allows the fridge to run on AC. Note, you can only operate the fridge on EITHER gas OR electric, but not both sources at the same time, thus, you have to turn off the gas switch before you can run on electric.

When this unit is running on electricity, it has to have the thermostat set for it to run.

Here's a link to the Dometic manual for your model.

Just follow the steps for running on electric and you should be OK.
Hope this helps.

Dometic RM2652 was working fine then stopped - no lights at the control panel above the doors.

Usually there is a short in the system when fuse is blown. Check the cord as sometimes mouse can damage the cord. It is a posibility.
Check power to the electronic board.

No electricity while using battery power

You will not have electricity while on battery power. Two different systems. Electric is 110VAC and battery is 12VDC. If on battery power the lights will work, the furnace will work (LP gas and 12v blower motor), the refrigerator will work (LP gas and 12v power for circuit boards) and the water heater will work (LP gas and 12v power for circuit board). The only way to have electricity while on battery is to install an inverter but you will need extra batterys and still will not have enough power to run the AC for any extended length of time.

I turned ON my LP gas detector in my Fleetwood '97 RV and left it turned ON. Three days later I noticed that my detector light was out. I toggled the ON/OFF switch and got nothing. I checked the fuse...

First I'd remove screws and pull detector out to see if perhaps any loose wires that may have touched each other or a ground. Second, check for any bad connections as well at solenoid on propane line feeding system. Being how it says it's a Motorhome, the propane detector usually has to be on to activate solenoid to open gas flow to appliances etc. If all connections appear good, you may have a bared (+) wire (short) that you need to look for. Area around wires coming from propane solenoid is a good place to start, seeing how they are usually exposed to the elements, more than interior wiring. You may end up having to disconnect one or the other or both to start with, and then re-attach one at a time to determine which way to go, As in a wire running to fuse box, or wire running from solenoid below at propane tank. Can't rule out shorted solenoid as well.

Electric and battery working fine but gas will not come on. It keeps clicking and then the red light comes on


Assuming this is on a travel trailer / RV, correct?

The red "check" light indicates that the fridge was not able to detect the presence of a flame from the burner area. This could be due to low LP gas pressure (causes different flame size), no LP gas (tanks are exhausted / turned off), damaged wiring going to the igniter / sense electrodes, defective gas valve, or damaged igniter / control board.

Last year my dometic rv fridge would run fine on propane then up and quit cooling, the freezer would warm up and the pilot light was still on. When I turned it off for 1/2 hour it started to cool with no...

Here is an interesting possible problem to look in to

First a bit of background on LP gas

Your LP system operates on 1/2 lb of pressure Not much more than a breath of air. Keep this in mind for a minute.

A lot of RV's have been built over the years using rubber hoses to connect LP gas to water heaters, furnaces, and refers.
Over time rubber and LP gas create an oil, if you have a low spot in your rubber line that oil will collect in the low spot - - Remember the 1/2# of pressure from earlier? Does not take a lot of oil build up to over power the 1/2 # of pressure and now you are not getting LP gas to your refer.
This is one possibility. The lines will need to be removed from the refer and other low setting items like the water heater and furnace also from the LP tank regulator and the using NO MORE THAN 10 pounds of air pressure blown out. BE VERY CAREFUL this oil is some really nasty stuff - cover the ends of the lines with a cloth in a plastic bag with some holes poked in the bag and rubber band it on.

But first lets look at some other options

Your refer has to have 12 volt power to it to operate
90+ % of all 12 volt issues are grounding problems.
Make sure you have at least 12 to 13 volts to the refer and that you have a good ground.

Next Are you getting gas flow to the burner?
If you are getting gas try changing your thermocouple They run a couple of buck and is an easy test.

If you have 12 volt power and gas have you noticed an ammoina smell?

This model has been known to lose the cooling unit
Hope this helps

Propane refrigerator?

Yes , when the refer needs to cool it will fire up only with the LP. In the electric selection it will work the same way. Do not fret , it is working ok.

Dryer not heating

  • There are two house circuits/fuses in an electric dryer's circuit.
    If one of them is tripped/blown, the drum may turn, but the heater will not operate. Reset the circuit breaker or replace the house fuse.
  • Outlet wired incorrectly.
    Have a qualified electrician verify that the supply voltage is correct.
  • Gas supply valve to a gas dryer is not open.
    Open the gas supply valve. See Installation Instructions for details.
  • LP gas supply tank is empty or there has been a utility interruption of natural gas.
    Refill or replace the LP tank. Call your natural gas utility company.
  • Dryer does not have enough air supply to support the gas burner.
    The dryer needs space around it for proper ventilation. Do not stack or place laundry or throw rugs against the front or back of the dryer. See Installation Instructions for details about installing a dryer in a closet or alcove.
  • Incorrect cycle or temperature has been selected.
    If the Air Fluff cycle or temperature is selected, the dryer will tumble without heat. Each cycle ends with a Cool Down period during which the load tumbles without heat. Check the location of the indicator on the Cycle Selector knob.
