    What to do if there is extreme condensation in my Hoshizaki EF2A-FS?
    • J
      Julie BuchananAug 13, 2025
      Extreme condensation in your Hoshizaki Refrigerator can stem from several causes. The cabinet thermistor might be loose or improperly installed, so ensure it's securely in place and correctly installed. The refrigerator door may not be shutting completely due to a defective gasket or misaligned hinges; adjust the door gasket or hinges as needed. The location of the refrigerator could be inadequate, so consider relocating the appliance. High relative humidity (over 75%) in the environment can also contribute to condensation; try to reduce the humidity levels in the room.

    How to fix evaporator frozen up in Hoshizaki Refrigerator?

      Edward StarkAug 17, 2025
      If the evaporator is frozen up in your Hoshizaki Refrigerator, start by cleaning the evaporator. Check the evaporator fan motor for binding fan blades and fix any binding. If the fan motor is defective, replace it. A defective control module or compressor relay could also be the cause, so consider replacing them. Additionally, check the refrigerant charge and lines for low refrigerant or component restrictions, and address accordingly.

      If there is no illumination in your Hoshizaki Refrigerator, first check if the light switch is in the “OFF” position and switch it to “ON”. If the light switch has an open contact, check and close it. If the light switch is defective, replace it. Also, the control module program could be the reason, so reset the control module.

      If your Hoshizaki Refrigerator isn't cooling, several factors could be at play. Start by checking the power supply—ensure it's properly plugged in, switched on, and that no fuses are blown or circuit breakers tripped. Especially on three-section receptacle boxes, confirm that the top receptacles are powered. Also, inspect all power connections and cord connections for looseness. If the power supply isn't within the correct specifications, make sure it is. Furthermore, the control module might be in alarm, in which case you should reset it, or it could be defective, requiring replacement. Other potential causes include a door switch that isn't engaged or is defective, faulty fan motors, a dirty condenser, loose or faulty wiring, a defective compressor relay, issues with the compressor exter...
