How to fix a loud humming noise in my Waeco CoolMatic MDC-90?
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 causes a motor start error in my Waeco CoolMatic MDC-90 Refrigerator?
A motor start error in your Waeco Refrigerator can occur if the rotor is stuck or if the differential pressure in the cooling system is too high (greater than 5 bar).
What to do if the cooling capacity drops in my Waeco CoolMatic MDC-90?
If the cooling capacity of your Waeco Refrigerator is dropping and the interior temperature is rising, here's what you should check: The vaporiser might be iced over, in which case you should defrost it. Also, high ambient temperatures or insufficient ventilation can cause this issue; move the cooling device to improve ventilation. A dirty condenser can also reduce cooling efficiency, so clean it. If a fan is installed, ensure it's working correctly; if it's defective, replace it. Finally, check if the battery capacity is exhausted and charge the battery.
Why does the compressor run constantly on my Waeco Refrigerator?
If the compressor in your Waeco Refrigerator runs constantly, it could be due to a few reasons. Check if the thermostat sensor has proper contact with the vaporiser and secure it if it doesn't. The thermostat itself might be defective and need replacement. Also, there may be a short circuit in the thermostat line.
Why does the electronic unit of my Waeco CoolMatic MDC-90 Refrigerator shut down due to thermal overload?
The electronic unit of your Waeco Refrigerator might shut down thermally if the cooling system is overloaded or the ambient temperature is too high, causing the unit to overheat.
What does it mean when the RPM is too low in my Waeco Refrigerator?
The RPM in your Waeco Refrigerator might be too low if the cooling system is overloaded, preventing the motor from maintaining its minimum speed of 1900 RPM.
Why does the fan in my Waeco CoolMatic MDC-90 shut down due to overvoltage?
Your Waeco Refrigerator's fan might shut down due to overvoltage if it's consuming more than 0.5 A on average or 1 A peak values from the electronic unit.
Why does the battery protection shut down on my Waeco Refrigerator?
The battery protection in your Waeco Refrigerator might shut down if the battery voltage is outside of the set range.
Why is the compressor not running on my Waeco Refrigerator?
If the compressor of your Waeco Refrigerator isn't running, several factors could be at play. First, ensure the connection between the battery and the electronics is solid; if it's interrupted, establish a connection. If there's a main switch installed, check if it's defective and replace it if needed. Also, see if an additional supply line fuse has blown and replace it. If the battery voltage is too low, charge the battery. Check for loose cables or corrosion affecting contact and re-establish connections. A battery with too low capacity should be replaced. If the cable cross section is too low, replace the cable. High ambient temperature or insufficient ventilation could also be the cause, so move the cooling device or clean the condenser. Finally, if a fan is installed and defective, re...
