What to do if the condenser fan is working but the compressor doesn’t operate in my KoolMore Freezer?
- C
  Cheryl HallJul 29, 2025
  If the KoolMore Freezer condenser fan is working, but the compressor isn’t operating, it could be due to a few reasons: * The plug of starter or heat relay might be loose. In this case, install the starter or heat relay. * The compressor itself might be defective, requiring a replacement. * The voltage could be outside the normal range (lower than 97V or higher than 130V). Using a voltage stabilizer can help.

  Sherry PrinceAug 3, 2025
  If your KoolMore Freezer is operating continuously, it could be due to several reasons: * The temperature inside the cabinet might be too high. Try to open the door as little as possible. * There might be too much storage inside. Remove some of the items. * There could be a leakage of refrigerant, which requires repair at a qualified service center. * The temperature inside the cabinet might be too low. In this case, change the thermostat.

The KoolMore Commercial Glass Door Display Cooler is a refrigeration appliance designed for commercial use, specifically for displaying products. It is available in models KM-MDR-1GD-8C and KM-MDR-1GD-10C.

Function Description:

This appliance is a commercial glass door display cooler, primarily intended for indoor use to store and display items while keeping them chilled. Its design emphasizes visibility of contents through an elegant, hollow glass door, making it suitable for retail and catering environments. The cooler operates efficiently within a broad voltage range and is equipped with a well-matched cooling system to perform optimally even above room temperature. High-quality polyurethane foam insulation ensures the interior remains chilled and conserves energy.

Important Technical Specifications:

Voltage Range: The appliance operates within a voltage range of 97V~130V. For appliances over 500W, a voltage stabilizer is recommended if the supply is below 97V or above 130V to protect the compressor.
Electrical Connection: Requires connection to a dedicated single-phase socket with a reliable earth connection. It is incompatible with inverters.
Refrigerant Class: A3 per ANSI/ASHRAE 34.
Noise Level: The sound pressure level of emitted noise is below 60dB(A).
Temperature Control: Features a temperature control knob for adjusting the interior temperature. Settings range from "COLD" (for less cooling) to "COLDEST" (for maximum cooling).
Climate Class Parameters: The manual provides a table detailing various climate classes (0-8) with corresponding dry bulb temperatures (°F), relative humidity (%), dew point (°C), and water vapor mass in dry air (gr/lb). This indicates the environmental conditions under which the cooler is designed to operate efficiently. For example, Climate Class 0 is 68°F with 50% humidity, while Climate Class 8 is 104°F with 70% humidity. The performance and energy consumption are influenced by the water vapor mass in dry air.

Usage Features:

Site Selection: Exclusively for indoor use. Should be positioned on a completely flat surface, well-distanced from heat sources (including direct sunlight), and not near ventilation systems or open windows and doors. A minimum gap of 10 cm from the wall is recommended to prevent limescale deposits and ensure adequate air circulation, especially at the back.
Leveling: Crucial for optimal performance and to prevent ice build-up due to poor condensation drainage. The appliance should be leveled using a spirit level, adjusting the feet as needed.
Temperature Adjustment: The interior temperature is adjusted via a control knob. The knob should typically be positioned upright for standard temperature settings. If stiff, a coin or similar tool can be used to turn it.
Operational Recommendations: To save energy and maintain efficiency, avoid frequently opening and closing the door. Allow sufficient time for the appliance to reach the desired temperature before restocking. Limit operation in the MAX (coldest) setting to no more than 24 consecutive hours, then return to a normal setting.
Storage Restrictions: Do not store combustible, acidic, corrosive substances, or items with flammable propellants (like aerosol cans) inside the cooler due to risks of deterioration, pollution, and explosion. Only use manufacturer-approved electrical devices inside the cooler compartments.
Safety: Ensure clear ventilation openings are maintained. Do not use unapproved mechanical devices for defrosting. Avoid damaging the refrigerant circuit. The appliance should not be operated by children without adult guidance.

Maintenance Features:

Cleaning: For optimal performance and hygiene, the cabinet should be cleaned with warm water mixed with 5% neutral soap. Glass parts should be cleaned with specific cleaning products, avoiding water that contains lime. Internal plastic parts should be cleaned with a mild soap solution mixed with water, avoiding harsh chemical detergents that could dull the finish or warp the plastic. Strong chemicals should not be used on metallic surfaces to prevent paint damage and compromise sanitary conditions.
Defrosting: Allow for a periodic defrost cycle to maintain efficiency.
Power Disconnection: Always disconnect the unit from the power source before cleaning or when exchanging parts. If the cooler is not in use for an extended period, disconnect it from power and perform cleaning maintenance before reuse.
Cord and Plug Care: Inspect the power cord for damage before use. If damaged, it must be replaced by the manufacturer or an authorized service agent. Never remove or modify the grounding prong. Detach the power cord by gripping the plug, not by tugging on the cord. Avoid using extension cords; if the cord doesn't reach, seek professional installation of a nearer outlet.
Servicing: Any servicing or repairs, including refrigerant handling and component replacement, must be conducted by certified technicians with valid certificates from an industry-accredited assessment authority, following manufacturer's guidelines and safety standards. Only manufacturer-approved components should be used for replacement.
Disposal: Dispose of the appliance in accordance with local environmental regulations, especially if it contains flammable blowing gases. Remove doors to prevent children from becoming trapped.
