Loud humming in your Waeco Refrigerator can stem from a few sources. A component of the refrigerant circuit might be touching the wall, restricting its movement; carefully bend it to create clearance. Alternatively, a foreign object might be lodged between the cooling device and the wall; remove it. If a fan is installed, the noise may be from the fan itself.
What to do if the compressor does not run on my Waeco CoolMatic MDC-50 Refrigerator?
If the compressor of your Waeco Refrigerator isn't running, several factors could be at play. It might be due to an interrupted connection between the battery and the electronics, a defective main switch (if installed, replace it), a blown fuse in the supply line (if installed, replace it), or a battery voltage that's too low (charge the battery). Also, check for loose cables or poor contact due to corrosion and ensure they are properly connected. The battery capacity might be too low (replace the battery), or the cable cross-section may be insufficient (replace the cable). High ambient temperature, insufficient ventilation (move the cooling device), a dirty condenser (clean it), or a defective fan (if installed, replace it) could also be the cause.
Why is the cooling capacity dropping and the interior temperature rising in my Waeco CoolMatic MDC-50?
If the cooling capacity of your Waeco Refrigerator is dropping and the interior temperature is rising, the vaporiser may be iced over (defrost it). Other potential causes include a high ambient temperature, insufficient ventilation (move the cooling device), a dirty condenser (clean the condenser), or a defective fan (if installed, replace it).
Why does the compressor run constantly on my Waeco Refrigerator?
If the compressor in your Waeco Refrigerator runs constantly, it could be because the thermostat sensor isn't making contact with the vaporiser (secure the sensor), the thermostat is defective (change the thermostat), or there's a short circuit in the thermostat line.
How to fix unusual noises coming from my Waeco CoolMatic MDC-50?
Unusual noises from your Waeco Refrigerator can stem from a few sources. A component of the refrigerant circuit might be unable to move freely because it's against the wall (bend the component carefully). Alternatively, a foreign body could be jammed between the cooling device and the wall (remove the foreign body). The noise may also be due to the fan, if installed.
Why does the compressor run for a long time in my Waeco Refrigerator?
The compressor in your Waeco Refrigerator might run for a long time if a large quantity of items has been frozen in the freezer compartment.
Why does my Waeco CoolMatic MDC-50's battery protection shut down?
The battery protection shutdown in your Waeco Refrigerator occurs because the battery voltage is outside the set range.
What to do if the compressor does not run often on my Waeco CoolMatic MDC-50 Refrigerator?
If the compressor in your Waeco Refrigerator doesn't run often, the battery capacity may be exhausted. In this case, charge the battery.
Why does the fan overvoltage shut down occur in my Waeco Refrigerator?
The fan overvoltage shutdown in your Waeco Refrigerator happens because the fan is consuming more than 0.5 A on average or 1 A peak values from the electronic unit.
What causes the thermal shutdown of the electronic unit in my Waeco CoolMatic MDC-50?
The thermal shutdown of the electronic unit in your Waeco Refrigerator occurs if the cooling system is overloaded or the ambient temperature is too high, causing the electronic unit to overheat.
