Your possibly getting a DC voltage interuption Your convertor can be over heating causing a temporary drop. You can chech this by turning everthing dc supplied on and watch to see if the check light comes on then. Primary is electric and if no electric then it is suppose to look for gas.

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

SOURCE: Light stays on check

Here's some info regarding the check issue you're experiencing:

Problem. Unit controls go to "check"
There is a common problem with, Dometic RM2807 or RM2811 and most later model Dometics with upper controls. The refrigerator's "check light" comes on or the refrigerator just shuts down seemingly for no reason. Another common problem occurs while on 120v. The refrigerator might switch to gas or just shut down even while you have a good 120v supply.

Answer. Dometic RV refrigerators with the push button upper control boards have a problem with the main power boards. The power board components are encased in yellow epoxy, reducing heat transfer. This tends to cause them to run too hot which in turn can often cause the power board to fail completely or cause problems such as listed above. We have found the only effective repair is to replace the power board. We do not use the Dometic replacement as they too can fail. The Dometic replacement also requires you to rewire the board and gas valve. The only board we recommend is the P-711. The P-711 not only will fix these problems but does not require the rewiring. It uses all the standard wiring. See Power Boards

Hope you find this helpful and best regards!

Chimes constantly. How do you turn them off?


Fridge keeps beeping or buzzing: The following is for Frigidaire models but others can be addressed similarly.

Several Frigidaire refrigerator models have an electronic control panel on the freezer door the owner can use to adjust the internal temperature, dispense ice and water and receive notification about issues such as the need to replace a water filter. The refrigerators also emit a beep for various actions and as an occasional alarm. Determining what causes the beeps necessitates some troubleshooting.
Temperature Controls ·A Frigidaire refrigerator's display panel blinks when the control panel is touched to set temperature controls. After pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, press the arrow buttons within five seconds to increase or decrease the desired temperature. If you do not press the arrow buttons within five seconds after pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, the refrigerator beeps to indicate the current setting will stay in place.

Door Open ·When you leave the refrigerator or freezer door open, the refrigerator beeps. Also, the "Door Ajar" indicator illuminates on the appliance's display panel. Shutting the door and pressing "Alarm Reset" stops the beeping and turns off the "Door Ajar" indicator light.
·The Frigidaire refrigerator has a control lock feature that prevents use of its control panel or dispensers when the unit is locked. When the control lock is active, a beep sounds when a keypad or dispenser is pressed. Release the control lock by pressing the "Control Lock" icon for three seconds. A beep will sound, and the icon's light will go out.
Power Reset ·A power reset is occasionally necessary if the Frigidaire refrigerator's control panel does not work normally or a reset function on the keypad does not work. A power reset involves disconnecting power to the refrigerator by unplugging its power cord from the electrical outlet, waiting 30 seconds and plugging the power cord back into the electrical outlet. When the control panel resets, a beep sounds. If the refrigerator beeps even after a power reset and the beeps' source is not known, contact Frigidaire.

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.

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.

My dometic 2611 dosent want to operate correctly. Check light consistantly comes on. I'mm connected to ac power all of the time. AC sometimes works for a day or so then it might switch to gas for no...


If your unit is automatically switching from AC to gas for no reason, then you either have a problem with the power supply or the lower control board. On the outside of the fridge, there is a black box located in the lower left corner, this box is the control unit. The control unit senses the incoming power source and automatically switches it to LP if no AC power is available.

Turn the refrigerator on and set it to auto. Let it run until you notice that it switches to gas. Immediately go outside and check for incoming 120VAC power at that lower board. If you have power there, then you have a bad board. If you do not have power, then you have a power supply problem. Check the electrical plug and outlet in the fridge compartment and also make sure that your GFCI's throughout the coach are ok.

Hope this helps,

Jeff
