SOURCE: I have a Randell 5ft

This unit uses Thermostat/Solenoid Valve Combination's to control the temperature

1. Rail 2. Bottom Storage

The way it works is the thermostat senses the need for cooling and energizes the solenoid valve. This allows refrigerant flow which cools the area it is controlling. Once the thermostat is satisfied the contacts open and the solenoid is de-energized closing the valve. If the solenoid is bad, the valve remains closed, no refrigerant flow, warm unit.

Test the solenoid coil (two wires) to see if voltage is present either with a volt meter, or remove the coil off the valve and place a screwdriver (insulated) through the coil hole and you should feel the pull like an electro-magnet (what a coil is).

go to this web site and check out the manual. It has some general info that can get you started on narrowing down just what is happening.
If it has been filled with freon 2x, there is an issue. Either it has a leak and it has not been found yet, or the amount of freon in the system is incorrect.
Usually, adding a timer is for defrosting purposes. Is there a frosting up issue?
It could be a thermostat issue but it is not set by the PSI, but by actual temperature. If it is a control that you have to set the PSI, an experienced refrigeration tech should know what to set it at.
Let me know if I can be of any further help.

The temp says 14 and 8 but should be -21 and 3? Can anyone help


Controlling the Freezer temperature
The freezer temperature can be set between -14°C (8°F) and -25?C (-14°F) to suit your particular needs. Press the freezer button repeatedly until the desired temperature is shown in the temperature display. Keep in mind that foods like ice cream may melt at -16?C (4°F). The temperature display will move sequentially from -14°C (8°F) and -25?C (-14°F). When the display reaches -14?C (8°F), it will begin again at -25?C (-14°F). Five seconds after the new temperature is set the display will again show the actual current
freezer temperature. However, this number will change as the Freezer adjusts to the new temperature. The top and bottom guards in the freezer of this model are the two star sections, so the
temperature in two star sections are slightly higher than other freezer compartment.

Controlling the Fridge temperature
The refrigerator temperature can be set between 7?C (45°F) and 1?C (34°F) to suit your particular needs. Press the fridge button repeatedly until the desired temperature is shown in the
temperature display. The temperature control process for the Fridge works just like the Freezer process. Press the fridge button to set your desired temperature. After a few seconds, the Fridge will
begin tracking towards the newly set temperature. This will be reflected in the digital display. The temperature of the freezer or the refrigerator may rise from opening the doors too frequently, or if a large amount of warm or hot food is placed in either side. This may cause the digital display to blink. Once the freezer and refrigerator return to their normal set temperatures the blinking will stop.
If the blinking continues, you may need to "reset" the refrigerator. Try unplugging the appliance, wait about 10 minutes and then plug back in.

The refrigerator does not work at all or it does not chill sufficiently.
• Check that the power plug is properly connected.
• Is the temperature control on the display panel set to the correct
temperature? Try setting it to a lower temperature.
• Is the refrigerator in direct sunlight or located too near a heat source?
• Is the back of the refrigerator too close to the wall and therefore keeping air from circulating?

My pizza prep-table freezes everything. I think it might be the thermostat. Could I be right


Hi

Sounds like you are correct, unless the door seals are not in good order, air leaking in can fool the thermostat.

If it has a top section that the pans for pizza ingredients sit in check that the airways are clear and that the tins and lids fit properly.

Why is there water pooling in my sandwich make up table? My reach in cooler, also?


During the cooling/freezing cycle condensation forms, this drips into a pan and then is evaporated by a heating element.
One of two things could be wrong.....
Your drip pan is clogged
or
your evaporator unit is bad

Hope this helps

All refrigeration equipment has some sort of temperature control, either a temperature control knob(1,2,3,4 or A,B,C,D settings) or the unit has a pressure control to control the box temperature. The pressure control would be in the bottom of the case with the compressor.
