Try cleaning thermocouple (sits just above flame like a probe) with a small piece of steel wool, especially in area where flame would touch underneath it. If that doesn't cure it, I'd replace thermocouple. If you have a multimeter, you can check voltage at board where thermocouple connects,,reading connected to board should be between 25 and 35 Milli-volts. Any less than 20 will cause problems at gas valve.

Freezer gets cold frig is hot. I replaced theromister.did no good


If your Dometic refrigerator is a tri-power model (12V, 120V, lp gas), check all modes. It is not uncommon for these units to fail to cool adequately in 12V mode, as that mode is only for KEEPING things cold while on the road.
If the failure exists only in 120V mode, replace the 120V heating element. If the failure exists only in lp gas mode, replace the burner and make sure that the jet is clean.
If the refrigerator does not get cold in ANY mode, verify that the door seal is making good contact all the way around and, if it is, you'll need to replace the coil assembly. (They are available on eBay and Amazon at a fairly reasonable price.)

Model# BWH30NLTB


Unit goes under sure heat name also.
My unit emitted unburnt gas smell the minute pilot started,
and was annoying during burner operation.
I discovered they built unit with primary pilot that had 2 ports.
They used LP and sealed off natural gas,instead turning lp/nat
knob on back activates second pilot for natural gas use.
This means natural gas goes thru LP pilot orifice and burns
slightly off during normal natural gas use(by design).
The unused natural gas orifice has 1 air mix hole and the LP orifice
has 2 air mix holes.
I carefully plugged 1 of the holes in the LP orifice and suddenly
pilot gas flame seated correctly on orifice port.Gone was the
unburnt odor of natural gas.
The typical flame in a flame appearance now was exhibited by
the small pilot,secondary pilot remained consistent with manual
picture.
Of course, to use with LP I would have to open blocked air mix
hole in addition to the other changes per manual.
Hope this helps someone with similar condition.

Our Dometic RM2652 RV frig has 2 yellow lights on which are indicated to be alert lights. The frig/freezer seem to be working fine.......????? Is something about to go out on it?


The 2 yellow lites... if you would... Is there and indication by description of what those 2 lights are?

Here are the modes:

OPERATING MODES

AUTO MODE

Press the AUTO/MANUAL mode selector button (2) to the DOWN position. The AUTO mode indicator lamp (A) will illuminate.

When operating in the AUTO mode, the AUTO mode indicator lamp (A) will illuminate. The control system will automatically select between AC and GAS operation with AC having priority over GAS. If the control system is operating on AC energy and it then becomes unavailable, the system will automatically switch to

GAS. As soon as AC becomes available again the control will switch back to AC operation.

If 120 volts AC is not available, the control system will automatically switch to GAS operation. Within 45 seconds the burner should be ignited and operating normally. If unsuccessful, the CHECK indicator lamp (B) will illuminate.

To restart an ignition attempt with the CHECK lamp illuminated or to clear (turn off) the CHECK lamp, press the main power ON/OFF button to the OFF and then to the ON position. The control system will attempt a new 45 second ignition sequence.

On the initial refrigerator start-up on gas (120 volts AC is not available), it may take longer than 45 seconds to allow air to be purged from the gas line. If the refrigerator has not been used for a long time or the LP tanks have just been refilled, air may be trapped in the supply lines. To purge the air from the lines may require resetting the main power ON/OFF button (1) three of four times. If repeated attempts fail to start the LP gas operation, check to make sure that the LP gas supply tanks are not empty and all manual shutoff valves in the lines are open.

NOTE: DO NOT continue to reset GAS operation if the CHECK indicator lamp continues to be illuminated after 3 or 4 tries.

If 120 volts AC becomes available while the CHECK indicator lamp is on, the control system will switch to 120 volt AC operation, The CHECK lamp will not turn off until the main power ON/OFF button is pressed to the OFF then ON position.

In AUTO mode operation, the temperature is controlled by a single temperature setting.

MANUAL MODE

When operating in the MANUAL mode, the AUTO mode indicator lamp (A) will be off, and the refrigerator will run continuously on the energy source selected by the control system.

NOTE: The food in the lower compartment may be frozen if the refrigerator is left on "MANUAL" mode.

STANDBY MODE . .

This control system contains a feature that will continue to operate the cooling system in the event of a failure of a major operating component. If the control cannot read the temperature sensor and operate at the preset temperature, then the control will run the cooling unit like the MANUAL mode.The refrigerator will continue to operate in this mode indefinitely or until a new sensor is installed and the
system is reset.

I posted the above information from the contents of the service manual. I can help you but... at the moment for sure I have come to the conclusion that ONE of the lights your seeing is the CHECK light. The mystery is... what is the 2nd light your seeing? Manual of Stand-by?

I am pretty sure we can sort this out but... we need to really communicate clearly and well. In our posts here.

Thanks for choosing FixYa,

Dometic RM3801. Propane ignition failure.


The older units has a 3 VDC glow coil the newer units have a 12VDC igniter.

Fromwhat your described above the next paragragh is your ignition system.

The igniter control voltages in the newer SPARK type igniters are (+) = 12VDC, (L)= high voltage lead (Spark plug voltage! I.e ruin your meter type voltage), (-)= Ground L is the lead that passes the HV spark from the control unit to the ignitor plate. The L lead should pass one heck of a hit if is workng correctly.
If not look at the HV lead to see if it is grounding out somewhere.

If the gas safety valve is not sensing gas pressure... you will not have 12VDC to the + terminal of the ignition moudule.

With the gas on and you have 12VDC at the ignition module + terminal then most likely the ignition module is bad.

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

Dometic rm2652 frige just stopped working, gas nor


Check 12V supply and fuses on lower board. If display functions okay, then look for yellow residue on back of refrigerator near burner. If yes, then cooling unit has leaked and needs to be replaced. See if recall kit has been installed, and check for 12V at both sides of limit switch. If no power on either side, then thermal link has blown, and need to be replaced, If 12V on one side, but not the other, than limit is tripped, and needs to be reset, by pushing button, or if not resetting, then replace, Check for obstructions to the bottom and top vent to make sure they are not blocked, On models with top side vent, check cooling fan for proper operation.

Dometic rm 2607 makes a gurgling sound when started in a/c or lpg . no cooling, in fact the inside of fridge heats up.help ? thanks


If your cooling unit is gurgling, then you have air in the system or a bad cooling unit. There is a process known as "burping" that should help repair this. It is a rather lengthy process and will require two people.

1. Access the rear of the refrigerator. Turn off the LP gas to the unit. Remove the LP Gas line and the 12Volt supply. Unplug the fridge.
2. Remove the screws in the rear at the bottom and then remove the screws from the inside.
3. Pull the fridge out and lay it down on it's right side for 8 hours.
4. Flip the fridge on it's top for 8 hours
5. Now the left side, then back to normal.
6. Reinstall the fridge and turn gas back on.

Hope this helps,
