What you are actually seeing
- Lights and display flicker together
- The display is completely dark but the cabinet is still cold
- Buttons do nothing, or one button in a row does nothing
- Not this fault: A code that appears only after a defrost cycle
Ranked causes on a Comptree Inc refrigerator
- Moisture in the control housing — Ranked here because: the compressor cabinets in the range use the same short rear drain as every other compact
- Display harness loose at the door or hinge — Ranked here because: importer cabinets carry the tightest clearance requirements in the compact class and are the most likely to be built in without any
- Marginal or interrupted supply voltage — Ranked here because: several units in the range run through an external supply or adapter, which is a discrete failure point
- Control latched in a fault state after a power event — Ranked here because: boards fail far less often than the sensors and supplies attached to them
- Demonstration, showroom or sabbath mode left enabled — Ranked here because: how the machine is loaded and dosed changes its behaviour more than most owners expect
What to check, and in what order
- With the display faulty, move the door slowly through its full swing and watch for the panel changing
- 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
- Unplug the cabinet for five full minutes, plug it back in and watch the panel come up — Tools: none — Estimated time: under ten minutes
- 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

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
