Randell ph120e2 make table, compressor running hot and not pulling down

Your compressor may have a internal leak caused by a bad high side valve. If the box is not cooling well and the compressor is very hot you may need a new compressor.

2 DOOR RANDELL. HOW TO REPLACE EVAPORATOR.

If you were told to replace the entire compressor unit (condensing unit), the person diagnosed the compressor is most likely bad. Depending on the age of the unit, it is hard to tell if this is a good decision. Overall condition plays a role in the decision process as well.

could be bad condenser fan motor or bad start components for compressor

First check to see if the fans are running in reverse because on there way out they sometimes do that ,also check to see if the coils are dirty ,that goes for both condenser and evaporator.

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).

Your system uses R-134a refrigerant.

If the compressor is running but it's not cooling, you probably have a refrigerant leak or possibly a restriction in your evaporator.

Unfortunately, refrigerant leaks are not DIY friendly, so my advise would be to call a competent repairman.

I searched till I found a Randell vendor in our state. They had the answers I needed.

should be on compressor

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.
