It will not turn on.

Try looking on side of the chimney / flue for a rewritable thermal fuse. Will have two wires coming out of it, reset button between them. Press button to reset. If still inop, use a test light and probe across the wires. Clip onto one and probe the other. If the reset button was pressed, and test probe light is on, then you have a bad thermal fuse.

If the thermal fuse resets, take a hard look at why it may have tripped. Operating off level, operating in high temps, blocked ventilation, leaking cooling unit.

More information required
does the compressor run ? It's the black round object behind the fridge if it's not running check the defrost knob on the bottom rear corner of the fridge sometimes they get stuck

It doesn't sound like you have AC going to the Refrigerator. Is that possible? If you do, then check the fuses located in the rear of the fridge on the electronic board. I hope this helps. ArctiCold Refrigeration We keep it cold

This refrigerator is equipped with a control system, which can automatically select the most suitable energy source which is available, either 120 Volt AC or LP gas operation. The refrigerator can be operated in either the AUTO mode (thermostat factory preset below the safe food storage temperature) or MANUAL mode (continuous operation - no thermostat control).

NOTE: Under certain cool weather conditions, the food in the lower portion of the fresh food compartment may freeze if operated for an extended period of time on the MANUAL mode.

A. A 12 volt DC supply must be available for the electronic control to function. The refrigerator will work down to 9.6 volt DC.

B. Press the main power ON/OFF button (1) to the DOWN position.

B. In AUTO mode operation, the temperature is controlled by a single temperature setting, on the energy source selected by the control system. (See Auto Mode)

C. In MANUAL mode operation, the refrigerator will run continuously on the energy source selected by the control system. (See Manual Mode)

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.

First thing to check is that the control switches are in the proper position, since some RV fridges require a particular placement for the fridge to operate on different power souces.

Check your owner's manual for troubleshooting steps for your specific fridge, beyond that, here's link to a site that provides a step-by-step troubleshooting guide complete with active links for each potential issue.

Here's a copy of the manual for your fridge model that you can download and print for free, just in case you don't have yours handy.

Hope you found this very helpful and best regards!

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,

You need to unpush the gas button on the front control. If the gas button is pushed in, then it is trying to run on gas and with the tank empty, it is unable to light. That is why the check light is coming on. If you turn the gas side off and have it on auto, it should switch to the AC side and work fine.

Hope this helps,

Jeff

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.
