Frequently Asked Questions - FS90 Gamko

How do I set the temperature on my Gamko FS90 fridge?

Locate the thermostat dial inside the fridge compartment. Turn it to the desired setting: typically, '1' is warmest and '7' is coldest. For normal operation, set to '3' or '4'. Allow 24 hours for the temperature to stabilize.

Why is my Gamko FS90 not cooling?

First, check that the power cord is plugged in and the outlet is working. Ensure the thermostat is not set to '0' (off). Verify that the door closes properly and the door gasket is clean. Allow the fridge to run for 24 hours after initial startup. If issue persists, clean the condenser coils at the back.

How do I defrost the Gamko FS90 fridge?

The FS90 features automatic defrosting. Ice buildup on the rear wall is normal and will melt during defrost cycles. If excessive ice forms, check that the door is not left open. Manual defrosting is not required.

How should I clean the fridge?

Unplug the refrigerator. Remove all food and shelves. Wipe interior surfaces with a mixture of mild detergent and warm water. Rinse and dry thoroughly. Clean the door gasket with soapy water. Avoid using harsh chemicals or abrasive pads.

Can I reverse the door opening direction?

Yes, the door is reversible. Refer to the user manual for step-by-step instructions. Typically, you need to remove the door, transfer the hinge components to the opposite side, and reattach the door. Ensure the refrigerator is level after reversing.

What should I do if there is water inside the fridge?

Water can accumulate if the defrost drain is clogged. Check the drain hole at the back of the fridge interior; clear any debris with a cotton swab or soft wire. Also ensure the fridge is level so water flows to the drain.

Why is my fridge making unusual noises?

Normal sounds include a humming compressor, gurgling refrigerant, and clicking of the thermostat. If you hear loud rattling or banging, check that the fridge is level and not touching walls or cabinets. Ensure items inside are not vibrating against shelves.

What to do during a power failure?

Keep the door closed as much as possible to retain cold. A fully stocked fridge will stay cold for about 4 hours. If power is out longer, transfer perishable food to a cooler with ice. Do not refreeze thawed food unless it still contains ice crystals.

How do I replace the door seal/gasket?

Purchase a compatible replacement gasket from Gamko or an authorized parts supplier. Remove the old gasket by pulling it out of the groove. Clean the groove and press the new gasket firmly into place. Ensure it seals tightly all around.

What are the installation requirements?

Place the fridge on a level, sturdy surface in a well-ventilated area away from heat sources and direct sunlight. Allow at least 10 cm clearance around the sides and back for airflow. Connect to a grounded power outlet. Do not use an extension cord.

Connect the machine to a suitable power supply.

When connecting the machine, ensure hands are dry and the socket is switched off

Connect the machine to the power supply only after having verified that the mains voltage corresponds to that on the serial number plate on the rear panel of the appliance.

(On page 10 of the manual)

maximum voltage variation tolerance allowed is ± 10% of the rated value.

It is recommended that the machine is installed with its own isolator switch as all pole contact separation.

All cables and isolators must be sized according to the rating indicated on the serial number plate. (On page 10 of the manual)

al start up

Prior to using the machine.

1. Ensure that the machine has not been damaged during transport

2. Remove any items from the ice bin

3. Clean inside the container with a damp sponge with warm water and a little sodium bicarbonate; rinse with clean water and dry carefully

Warning: When switching on for the first time or after a prolonged period without use or after cleaning, the tray in the evaporator area must be filled with water (Fig. 2). In order to carry out this nation, lift the door, slide back the curtain and pour clean water into the evaporator tray. Subsequent cycles this will not be necessary.

Check the connections to mains water and electricity, open the water supply tap. To start the machine, press the illuminated switch (Fig. 3). It is recommended to not use the first five cycles of ice.

ice maker is equipped with a thermostat inside the ice cabinet (Fig. 4), which stops the machine and the production of ice when the sensor comes into contact with the ice accumulated inside the cabinet. Never switch off the water supply when the machine is on, do not obstruct the intake ducts.

Note: After removing ice, free the control bulb from any ice residue to ensure that ice making restarts swiftly (Fig. 4).

Cube adjustment

Cube dimensions can vary depending on varying conditions. To adjust the size of the cube, rotate the adjustment screw (fig.5) clockwise to increase the sizeant anti-clockwise to decrease the size.

Malfunction

In the event of a Fault, it is recommended to disconnect the electrical and water supply

1. Check that the water supply tap is on.
2. Check that power, that the plug is correctly inserted, and that it is switched on and the fuse has not failed
3. Check that there are no abnormal vibrations.
4. If there is a water leak, stop the machine first before making any adjustments.
5. If ice production is low, check that the condenser is clean, check for the build up of limescale accumulation of the sprayer nozzles.
6. To Check that the cabinet sensor is working: rest an ice cube on the bulb inside the container. This should stop ice production within 1 minute, when the cube is removed. Ice production should restart within 1 minute.
7. Between summer and winter the cabinet thermometer may vary the maximum quantity of ice in the cabinet, in order to adjust this value, contact an authorised installer.

Cleaning and maintenance

Disconnect the electrical power supply from the appliance to perform maintenance and cleaning operations

Use a cloth dampened with a specific chlorine-free product for stainless steel to clean the case.

Cleaning the air condenser.

To maximise the efficiency and life of you machine, the condenser at the front of the machine must cleaned periodically (Fig 6)

Do not use wire brushes or blunt objects to clean the condensor, use a soft brush or vacuum with a suitable nozzle. Where a condenser requires cleaning with a cleaner other than a brush or vacuum. This should be out by competent engineer.
