External unit on my walk-in cooler will not shut off. Seems to be due to the Ranco Pressure Sensor. How do I fix or adjust?

External unit fan runs constantly this year.

You may have a Freon leak at the compressor. Running this unit at low pressure will only make it leak that much more. Have a technician check it and refill is there is a fill port available.

@50/300 I assume it's a med. temp R-22 pump down walk in. Head pressure sounds a little high, probably been overcharged to compensate for a restriction in the metering device (or malfunctioning TXV). Check the solenoid (if pump down), metering device, and filter driers first. If that fails, lineset restriction or non-condensables/water in the charge would be next on my list.

How can I adjust the temp. on a norlake walk in cooler?


There are many variations for a Norlake system
I assume the cooling coil hangs from the ceiling of the cooler and the condensing unit sits on the top?
The temperature is controlled by a control that is located in the condensing unit on the top of the cooler. This can be either;
\ a digital thermostat. You will need the progam key to get in
\mechanical thermostat. Adjust the dial setting
\ pressure stat. Adjust the dial setting

Probably best to get a technician in

Wine cooler #ULN-75BWC-00 motor seems to have shut off and no longer cooling. Please advise possible issues & parts to be replaced. Unit about 7 yrs old.


the motor could be defective or it could be low o refrigerant causing the pressure switch to not kick on the fan. Could even be wires have come loose from the fan. If the fan does not work it won't cool. however it mould most likely cosy you more to fix if you take it to a shop to have it repaired if you have the tools to test it with I can help you so let me know if you have a test meter volt ohm meter and I can tell you how to test the system.

I just bought a wine cooler not sure where to start to fix it. Fans will not turn on


Hi there.........i take it this is a used / second hand wine cooler......if so you've probably discovered why its been discarded........problem could b due to a faulty compressor unit....the fans are usually wired through the compressor...and run in conjunction with it........if the compressor isnt running then the fans are out .........if the comressor is running then check that there is nothing impeeding the fans rotation.....check for broken or damaged wiring.....check for tampering by someone else....check continuity of wiring through fan coils.........check for faulty starter unit on compressor

The unit has a temperature swing adjustment screw located behind the thermostat plate.If you remove the knob and the face plate you will see it,It can be adjusted there.It may also be the thermostat bulb is going bad or touching something and giving a false signal to the compressor.

Refridgerator Not Cooling


If top is compleatly warm it is probley the fan motor, lot of failures on them. Replacement one will be a different looking motor. Verify motor is not turning, located in the back of the freezer in the top middle, behind small grill. Will see fan blade pointed up, should run whenever compressor is on.
