What you are actually seeing
- The display is completely dark but the cabinet is still cold
- Buttons do nothing, or one button in a row does nothing
- A code appears and the cabinet keeps running
- Not this fault: A dark display and no cooling at all
Ranked causes on a Contoure refrigerator
- Marginal or interrupted supply voltage — Ranked here because: a coach appliance can be fed from shore power, a generator, an inverter or the battery bank, and a supply that is present but weak produces faults that look like component failures
- Display harness loose at the door or hinge — Ranked here because: a few hundred miles of road vibration loosens connections, fasteners and plumbing joints that would never move in a house
- Control latched in a fault state after a power event — Ranked here because: the converter and the transfer switch sit between the appliance and whatever is actually powering it, and both fail in ways that look like a dead machine
- Moisture in the control housing — Ranked here because: a door latch and gasket that has been slammed by road motion is a routine finding
- Demonstration, showroom or sabbath mode left enabled — Ranked here because: coach appliances are used intermittently and stored for months, which produces its own fault pattern
What to check, and in what order
- Confirm the outlet with a lamp or a tester, and plug the cabinet directly into it with no extension lead
- Unplug the cabinet for five full minutes, plug it back in and watch the panel come up
- Look up the button combination for demonstration and sabbath mode in the owner manual and check whether either is set
Steps you can safely do yourself
- Look up the button combination for demonstration and sabbath mode in the owner manual and check whether either is set — Tools: owner manual — Estimated time: a few minutes
- Put a thermometer in the middle of the compartment for an hour and compare it against the display — Tools: appliance thermometer — Estimated time: about an hour
- Press every button on the panel in turn and note which respond — Tools: none — Estimated time: a few minutes
- With the display faulty, move the door slowly through its full swing and watch for the panel changing — Tools: none — Estimated time: a few minutes

When to call a technician
the panel is confirmed dead with good supply and no mode set, because board diagnosis needs the service manual a code points at the defrost circuit, since that means a heater, a thermostat or a timer in the sealed area there is any sign of moisture, corrosion or a burnt smell at the board
